Lesson details
Key learning points
- Use external components to extend functionality.
- Control external hardware components using programs and GPIO pins.
- Use wireless communication to send and receive messages.
Keywords
GPIO pins - General Purpose Input/Output (GPIO) pin, is a programmable pin found on microcontrollers and other digital devices
Circuits - is a complete path that electricity can travel through. It’s like a loop that lets electric current flow
Wireless - the transmission of data between devices without using physical cables or wires
Common misconception
Sending and receiving radio signals broadcasts to all devices that have radio capability.
A radio channel can be set which means that only devices on that same channel will receive those broadcasts.
Equipment
Access to a device that connects to the internet to use the micro:bit makecode website. It would be beneficial for pupils to have access to two micro:bits, USB cable, wires and an LED.
