Micro:bit - Using the radio function - Barclays Code Playground
Key Stage: Key Stage 2 Coding Language: Micro:bit Resource type: Lesson plan + teacher guide
Resource overview
One of the Micro:bit's features allows the devices to communicate with each other through radio signals. Use these resources to introduce this function to the class and challenge them to find creative ways of using the radio.
-
Key resource information
- 1. You will need: Laptops or desktop computers, BBC micro:bits (one per computer), https://microbit.org, At least one set of walkie-talkies and a basic radio (digital or FM/AM is fine) or an online radio feed
-
Teaching assessment opportunities
- Have the children play out the activity from the lesson
- Swap over roles so that the students get a go at both. Remember to re-programme the micro:bit
-
Lesson length
- 45 minutes
-
Pupil objectives
- "I can use the micro:bit radio feature to communicate between two or more micro:bits”
- “I can design and construct models and explain my solutions.”
- “I can demonstrate a range of basic problem solving skills by building simple programs to carry out a given task, using an appropriate language.”

Introduction to variables - Micro:bit
In a program, data values can be constant or variable. If data values are variable they can be changed by the program and the user, for example, when the user is asked a question like their age. Variables may change during program execution. In this lesson use variables to track the score in the project using inputs on the micro:bit

Using the accelerometer - Micro:bit
Lots of modern devices are able to tell what position they are in using built in accelerometers to measure their precise orientation. The Micro:bit's accelerometer can be used in the same way so you can use it as a controller or a sensor to start or interrupt your program. Use these resources to help your class learn the basics of how to use the accelerometer.
