Hello, welcome to today's lesson.

Today is lesson six of your design and technology lessons where we're exploring reactions and control in design and technology.

My name is Mrs. Mee and I am your design and technology teacher, and if you remember, if you've been with us previously, you'll remember that we've explored quite a lot.

We've looked at electrical systems, we've looked at mechanical systems, we've then looked at the need for control in design and technology, and we started programming in micro:bit.

And then if you remember back to lesson four, I gave you a design brief.

Do you remember what that design brief is? That's right, you are being asked to design and make a smart device that's suitable for young children to encourage them to recycle.

So that is your design brief.

And if you remember back to lesson four, we actually explored how to create a design specification and we explored the problem and we looked at some smart devices and then we came up with some really good ideas on how we could solve that problem.

We then looked at developing our idea in our last lesson and we actually selected a final idea.

Do you remember how we selected our final idea? That's right, we evaluated our ideas against our design specification to judge which one was the best idea, and Mrs. Mee chose her idea three.

And do you remember how we demonstrate how did we communicate our final idea? What did we use? That's right, we used an exploded view.

So we used an exploded view to show what? What were we trying to show? That's right, we were trying to show how the parts would separate.

So Mrs. Mee worked with you to create an exploded view and then we actually created a model of our final idea.

So we created a quick prototype model.

So we did that to explore how the parts go together, what it's going to look like in 3D, how it might stand up, and it allows us to see the product in a bit more detail to be able to evaluate it.

Now, because our product is a smart device that needs to attract young people to recycle, we've got a product that we've made that's suitable for young people and we've got a product that you can use to recycle, but is it a smart device yet? No.

So that's why in today's lesson we're going to explore building our smart product, and we're going to try and make a prototype of a smart product.

But before we do, we're just going to have a look at some examples of how smart technology and new and emerging technology is used in products.

So I'm glad that you've joined me today.

I'm just going to introduce you to the lesson and introduce you to what we're going to cover and then we shall begin.

Okay, so in today's lesson we're actually going to start looking at exploring the use of new and emerging technology and we're going to look at how it's used in products.

So let's begin.

Remember the rules.

Now today, we're going to look at building an electrical system, it's really important that you don't give up if something goes wrong, it's really important that you explore and experiment and have fun, try out new ideas.

You might come up with a better idea than me and I really hope that you do.

Be confident and make sure that you play safe.

So anything that you might be exploring with today, make sure you're playing safe at all times.

Now what you're going to need in this lesson is you're going to need some paper and a pencil, you're going to need your exploded view of your model or you might want your actual model, you're going to need a computer and access to the micro:bit website.

So if you pause your video, make sure you've got all of those things.

When you're ready, come back to me and we'll continue today's lesson.

Excellent! So hopefully now you've got everything you need.

So let's continue exploring the lesson.

Okay, so in today's lesson, you should have already completed the intro quiz.

We are going to investigate smart technology in a little bit more detail, and we're also then going to look at developing our electrical system that we're going to use to make our product smart.

And then we're going to have a look at annotating our exploded view.

So you do need your exploded view to hand.

So key words that we're going to look at this lesson, we're going to look at new and emerging technology.

Now this is a term used to describe new technology.

However, it may also refer to the continuing development of an existing technology, or when a piece of old technology is used in a very new way.

We're also going to use the word innovative and I'd like you to think about being innovative today, and this refers to the creation of new and original ideas.

Looking at the word input again.

So this is a component or action, which when operated initiates an electrical system.

And we're going to look at the word process, and this is the transfer of electrical energy from the input to the output, and it is the action taking place between the input and the output.

We're also going to be using the word output again.

So this is where a component or action that is activated after the process.

So before we start building our own electrical system, I thought it would be good to look at some examples of existing smart technology.

So we are going to be using a micro:bit and Mrs. Mee will get her micro:bit out when we're ready to use it.

But let's have a look at smart technology.

So what do we mean by smart technology? Is it a piece of technology that knows everything? Or is a smart technology is smart technology, sorry, able to connect, share, and interact with its user? And what does this link to, what have we already spoke about previously? That's right, a smart device.

Now we're making a product such as a container to contain recycled rubbish but we are actually making it smart.

So we're going to explore smart technology today.

So which option is it? That's right, it's option two.

It's a piece of technology that you can connect, share, and interact with its users and other smart devices.

So it's a term used to describe new technology but actually, smart technology might be using an old piece of technology but using it in a different way.

So using it in a new way, in a different type of product.

So an example would be a voice activation.

So I'm going to show you some examples of products so we can actually explore smart technology some more.

Now we looked at Alexa in the previous lesson, didn't we? So Alexa, what's the key thing about Alexa? What can Alexa do? Is it just a speaker? Does it just make noise and play music? What is the main piece of technology that is used? That's right, it's voice recognition, isn't it? So what's really good about Alexa is that we can talk to it, it's like having another person in your house, isn't it? And I actually really like that Alexa's got a name as well.

But it's not a new piece of technology, is it? It's been around for a long time.

But it's a very different way of using that technology.

And it's innovative.

It's a new inventive way of using this technology.

So Alexa is a great example of using new and emerging technology.

Another product that we looked at in the previous lesson was the Apple Watch.

Now, or a smartwatch, let's not use the word Apple Watch, you can get lots of different smartwatches.

Is it just a watch? Can you just use it to tell the time? What is the main piece of technology used? Touch sensitive.

So I can touch the watch and it will actually activate things on the screen.

Now that's not a new piece of technology, is it? That's been used for a long time, hasn't it? You might have a tablet or an iPad and this technology has been used in that for a long time, but it's quite new to use it within a watch.

So it's very innovative use of a piece of technology.

Now let's look at this one.

Has anybody seen this before? It's the Ring Doorbell.

Now you might have one, we've not got one.

Is it just a doorbell, right? So it just rings and alerts the user when someone's at the door? What is the main piece of technology used in a Ring Doorbell? What's made it so very popular? That's right, the camera, but also the remote access.

So if you have a Ring Doorbell, you can see who's at your door while you're miles and miles and miles away because it sends a signal from your doorbell all the way to your phone via Wi-Fi to tell you who's at your door, and you can actually speak to them.

So it's quite awesome, isn't it? So it's using kind of new and emerging technology and making, you know, innovative use of it.

So, what makes it smart? Use of new and emerging technology? The fact it connects, shares, and interacts with its users.

So bear these things in mind.

How are we going to get the users to interact with what really, we could call in my design, it could just be called a bin, couldn't it? How are we going to get young people to interact with a bin? So have you heard of the term smart home? That's right, so let's have a look at a smart home.

What I'd like you to do is I would like you to research smart homes and investigate all the ways in which new and emerging technology can be used to improve how a user interacts and connects with their environment.

Pause the video and research smart home, see what you can find.

Maybe your house is smart, my house isn't smart.

I don't like too much technology in my house.

But some people do.

So have a little research and tell me what you think it is.

Fabulous! Have you had a look? So a smart home is a home that interacts with the users.

So here are some of the ways it could interact.

So voice recognition.

So if I had a smart home, I could say curtains close, and my curtains would draw close.

Curtains open.

It senses movements.

So for instance, if I had a smart home and someone walked up my drive, the camera would sense that movement.

It senses temperature.

So your smart home can be set so that when the temperature gets too low, which it is at the minute in Mrs. Mee's house, the heating will come on.

Sound recognition.

So it turns on lights.

So I could clap to turn on my lights.

I could pair all of these smart devices with my phone and everything could be controlled by another device.

You can also set schedules of patterns.

So you can say, "At this time, "I want the heating to come on.

"At this time, I'd like you to boil my kettle "and make my coffee." So you can have lots of smart devices all throughout your home that uses technology which interacts with another piece of technology.

So how cool would that be to have a smart home? So a smart home is one that makes use of new and emerging technology to allow the user to connect and interact with the environment.

Is this true or is this false? Have a think and point to the screen.

That's right, it's true.

A smart home is a home that interacts, allows the user to interact with their environment.

So now that we've explored smart devices and we've looked at the use of smart technology, and we've looked at the use of old technology, and new and emerging technology, let's think about developing an electrical system for our model.

So you are going to now create an electrical system for your product to make your product smart.

So we've got to think about how we can develop it.

We are going to look at integrating new and emerging technology.

Now, you will not have the capability to put those components necessarily on your module, you will simulate it on screen.

So we need to think about how we're going to get our users to interact and connect.

So let's remind ourselves of what we know about the key parts of an electrical system.

What is the input? Is the input a component or action in order to get the circuit working? Is it a component or action that will be activated after the process? Is it the transfer of power between the input and the process? Or is it the part of the product that makes it work? Well technically, it's the component or action in order to get the circuit working, but that really is the part that makes it work, isn't it? So we could have gone for options one or four.

So can you identify the input process and output on this simple circuit here? Do you know what it's a simple circuit of? That's right, it's a simple circuit of a light.

Do you know the component's name? Yep, it's an LED light, well done! So can you identify where the input is? And there's no switch on there.

So what do I need to do to activate it? That's right, I need to connect the wires to allow for that flow of electricity.

So just connecting those wires, that becomes my input, and I could connect a switch there, couldn't I? The process is the transfer of electricity and the output, of course, is the component that is activated.

So we are now going to explore how we can use various inputs, outputs, and integrate them into a product to make it smart.

So take a look at your exploded view and make some notes about how you would like the user to connect and interact with it.

What would you like the user to do? Shall I show you Mrs. Mee's example? So here's Mrs. Mee's example.

Here's my exploded view, I've annotated it with initial ideas that I would like to explore.

So the first idea I've got, I'd like the eyes to light up in a pattern to encourage the children to interact with the bin.

So they could go, "Ooh, that looks exciting." I would also like to create a point system so I can get siblings within a family maybe, or within the same household to compete with each other.

So one child might want to dispose of more recycled materials than the other so they can get points.

I would like the user also to activate it using their feet.

So those are my initial ideas.

So pause the video, get your exploded view, make some notes on it to tell me what your initial ideas are and then when you're ready, resume and we're going to start exploring the electrical system.

Fantastic, are you ready to move on? Well done.

So what we're going to do now is we're going to explore how we're going to make our prototype smart.

Now remember, there's only so much we can do with our we've simulated it on screen to make it smart.

So we have to really kind of use our imagination a little bit.

But what we're going to do is look at some various inputs and outputs that you can use to make your products smart using the micro:bit, and we're going to use it on screen.

So here are some of the inputs we could use.

We could use a switch, we could use sensors, such as sensing sound, movement, light, and temperature.

The outputs that we could have are sound, we could make the micro:bit make a sound, we could make it make movement.

So we could make something move or we could actually make it light up.

So what I'd like us to look and what I'd like you to do now is I'd like you to quickly remind yourself and quickly explore how you can create a basic LED message-board using the micro:bit.

So how can you programme the micro:bit using the switches and inputs and the LED's display as an output? Now, Mrs. Mee has done a quick demonstration for you just to show you how you might do that.

So let's have a look.

So remember, you go to let's code, and you go to MakeCode editor.

And you go to New Project, and Mrs. Mee saved it so she can actually find all of her old projects as she is progressing.

So electrical system.

I'm calling it a prototype.

So this is my prototype for my electrical system.

So if you remember, you've got those key and loops already in there, start and forever.

So let's just put the start one back in there and let's just look at how it works.

So let's use the show LEDs.

Now Mrs. Mee's just dragged these show LEDs into forever and then I'm going to do another one.

And if you look on the left-hand side of the screen in a moment you should see the light simulator on the screen.

So I'm drawing numbers because if you remember, on mine, I want this to count.

So I'm just exploring what I can do.

So you can see it appearing.

So one, two, then it stops.

So now I'm doing a number three.

And then if I press play, it should count one, two, three and because it's forever, it goes one, two, three, again, one, two, three.

Now let's have a look at the other inputs.

So let's explore them.

So I want it to work on the use of a button.

So if I use on button A, it will go one, two, three.

So at the moment, it won't play unless I press on and I have to press the button.

So on the actual micro:bit, for it to work I've got to press the button, and it only does it to the end.

So it just says one, two, three.

So I'm wondering how can I get it to do it forever.

Now I'm looking in the basic icons and you see what Mrs. Mee is doing now? She's exploring, and that's what you need to do.

So what we need to use in order to keep that forever loop is we need to use the logic tool.

If mm is true, then mm.

So if A is pressed, then one, two, three.

So here we go.

So now I've controlled it so A is pressed one, two, three, and it won't do it again because A needs to be pressed.

So I have to press the button each time.

Okay? So that button is interrupting that flow, that process.

So the button is the input, the flow of electrical current is the process, and the output, of course, is the one, two, three, the LED lights.

So pause the video, have a go at doing that for yourself.

When you've finished having to go, resume the video and we will continue the next part of the lesson.

Well done, did you have a go? Did you see it on screen? And hopefully you had a bit more time, a bit longer than me to do that.

And hopefully, you can screenshot, you can take a picture of your screen by pressing Ctrl Alt and I forgot what it is on your PC, but on Mrs. Mees Mac it's Shift Alt and three and it takes a picture of my screen.

You should have a little icon that says Print Screen or PRT Screen.

Press the Shift and that and it should work.

So you can share that with your teachers.

Okay, so let's move on.

Now what we're going to do is we're going to explore the micro:bit a little bit further.

So how can we really make it smart? So pressing a button isn't very smart, is it? What do we want the bin to do? So when I go towards the bin, I want it to sense me or the litter.

So let's explore some of the built-in sensors.

Now, you're not going to have the answers necessarily at the end of today's lesson, but what you are going to need to do today is you're going to need to explore and experiment to find out how you're going to programme your product to interact with the end users.

So we're going to explore some sensors, we're going to explore movement, sound, and light.

So we're going to explore how that micro:bit can detect movement, sound, loud noises and light, and then we're going to stick with the light as an output.

But there are other outputs we could incorporate and that's something you can do, but I'm just going to focus it around this.

So again, I've got a short video which goes through how to explore with these inputs.

So go to let's code, MakeCode editor, New Project again, and then give it a name.

So when you log on to the micro:bit website, it automatically saves all your old projects.

You haven't got to go to File and Save, it just does it for you.

Really clever.

So Mrs. Mee's bringing over from the input all of the different options you've got.

So you can activate it on the press of a button, which isn't smart, you can activate it by shaking it.

So that's detecting movement, isn't it? And there are different ways you can set look.

So if you click on the drop down arrow, you can actually activate it.

So you don't have to rigorously shake it, you could turn it.

There are lots of other input options.

But remember, we're focusing on movement, sound, so on Loud sound do something.

And you can simulate that.

So you'll notice as I'm dragging in new icons, you'll notice on the micro:bit on screen, it's got the word shake and it's also got a bar and I'll show you how those work in a minute.

The next one we're going to use is light.

But to use the light one, we're actually going to go into the logic.

So I'm just going to show you what tool you'd need to use for lights.

So light needs to go in this toolbar.

So you need to set light level equal to, then it'll activate or less than or more than.

So you'll see here Mrs. Mee is showing you.

So this is more than, that is less than.

So if the light level is less than 100 then that'll activate it.

But still, I need something to make that work, don't I? So Mrs. Mee's dragging the if and it's still not lit up, why isn't it lit up? Because it needs to go in the loop.

So you can see now it's activated.

So if light level is less than 100, then, and I can get it to do something.

So we've got sound, movement, light level, three different inputs that you're going to explore.

Light level is less than, or more than, and you can change the value.

And that's something you'll need to experiment with.

How light is at 100, how light is 50? And then you can put your pattern in there so you can see it being activated.

So you can see there how I can drag that circle to change the light level.

So I'm just going to show you, okay? So if I move it up, look.

Move it down, sorry.

If I move it up, when it gets to 150, it will go on.

And it should turn off now.

And it's not quite turning off, I wonder why.

So technically, that should now turn off.

So what I'm doing now is putting the opposites.

So if light level is more than, it activates the one.

But then what I'm going to do is look at how I can change it so if light level is below 150, then that turns it off.

So explore and tinker and here we go.

Okay, so if light level is less than 150.

There we go.

So we should change it or you can have it blank, it's entirely up to you.

So you can see there's lots of exploring to do.

And even when Mrs. Mee is doing it, there we go.

So that two wasn't perfect at first.

So if light level is more than 150, on.

If light level is less than 150, display the number two.

And there's Mrs. Mee dragging the light level up and down to show you.

See? One, two.

One, two.

So that is how you use the input of sensing light.

Now what I'm going to do is show you how you would use the input shake.

So we're just going to add, I'm just going to add the existing show icon.

And if you remember, you click on the arrow, you can change the shape.

So I'm going to have big heart, little heart, big heart, little heart.

Flashing heart.

And then on screen, you can simulate it.

So with Mrs. Mee's micro:bit, you can physically shake it, but you might not have a physical micro:bit.

So you can see there, you can physically shake it on screen, which is really exciting, isn't it? So physically shaking it on screen, whereas if you had an actual micro:bit, Mrs. Mee will just grab hers out of her box, you could also physically shake it as well.

But if you remember, I won't work unless you've got battery connected to it.

So that is showing you, okay, how you can programme it to work with light level, programme it to detect movement, and then I've shown you now obviously how you can make it do that forever.

So here's my actual micro:bit what it remembers.

Oh look! Excellent.

So I've set a different programme in here.

So that is shake, it will shake, when you shake it, it will go big heart, little heart, big heart, little heart, and then if the light level comes up then it will change from number one if it's above 150, and if it's below it will change to the number two.

So this is something I want you to experiment with.

How can you activate different things? Now, I've got a challenge.

I need flashing eyes and a counter.

Hmm, and I either want it to be activated when someone puts a rubbish in, or by pressing this here.

So I've really got to think about what sensors I might use.

What do I want to sense? Movement, light? Hmm, sound? Could I have when someone walks by my bin, the eyes light up? So you see here with sound, look, on loud sound, show Hello! And you can see you can see the microphone there? You can drag it up and down to make a loud sound.

But if you were to programme that physically, here, you've actually got a microphone on here that could detect it, I'm just looking for my microphone icon.

The microphone's not on at the moment.

So it's not been programmed to detect the microphone.

So it's obviously wiped off that programme that I used.

So hopefully that gives you an idea.

So what I'd like you to do is I'd like you to pause the video, I'd like you to use the micro:bit online and I'd like you to explore with the different various inputs.

Now I've demonstrated movement, sound, and light, but maybe you could actually demonstrate and explore some more.

And there are some really good projects that you can use on the micro:bit website.

So please, if you want to do something, have a look and you can either search it by project or you can search it by input.

So hopefully, you have fun doing that.

Okay, so when you've finished, resume the video.

Excellent.

So have you had a go? Good! Let's move on.

So what I'd like you to do now so the microprocessor, sorry, the micro:bit is a microprocessor that has key components built in.

So what are the components called that sense the following? So we've sensed movement, sound, and light, but these components have certain names and you're probably not going to know these names.

So shall I tell you and hopefully you can show off and tell everyone else what you know? So the sensor that senses movement, you can use what we call a tilt switch.

So a tilt switch senses movement.

The sensor to sense sound is a microphone and then the one to sound sense light is called LDR, light dependent resistor.

So now that we've explored the electrical system, what I'd like you to do now is take out your exploded view and I would like you to apply what you've explored by using the micro:bit.

I would like you to think about how you're going to make your product smart.

So I'd like you to annotate your exploded view to communicate how you're going to allow your product to connect and interact with the end user.

So let Mrs. Mee show you hers.

So here's Mrs. Mee's exploded view, and I have annotated it.

So I will use LED display as an output that will be activated by sound, I will use the microphone as an input to detect sound.

So when someone creeps near my bin or someone comes into the kitchen, the lights light up.

And remember, Mrs. Mee is going to make four bins with four different faces.

So it might have different coloured lights for different bins to really get the children to go, "Ooh, what's that?' And then they'll realise then, that if they put recycled waste into those bins, the other LED display will count and it will count each time they add more litter into the waste bins.

Okay, so pause the video.

When you've finished doing that, resume and we will conclude today's lesson.

Fantastic, did you have a go? Well done.

I hope you've learned lots and I've hope you've really enjoyed exploring using the micro:bit.

So there's my exploded view and I hope you've had a go at doing yours.

So this lesson we've learned a lot, we've done the intro quiz, we've looked at investigating smart technology, haven't we? We've looked at smart homes, we've developed our own electrical system and we've explored some ideas for it at least and we've annotated our exploded view with a plan on what we might do.

So this is something you might want to explore further.

But if you'd like to share with us some of the ideas, maybe you want to share your screen, Print Screen and take a grab, take a photograph, and get an adult to share your work with us.

Excuse me, Mrs. Mee's got a the frog in a throat, I think.

Share your work with us via an adult @OakNational using the hashtag #LearnwithOak and I really hope you've enjoyed today's lesson.

I've really enjoyed exploring with you and I look forward to seeing you in next lesson where we're going to plan how we're going to make both our electrical system and our final and physical prototype.

Thank you, goodbye.
