Using Micro: bit Radio to Transmit and Display Sensor Readings

In this short video, a demonstration of the micro:bit taking readings from a TMP36 then displaying the temperature on the LED display can be seen. Here the micro:bit then uses the inbuilt radio to transmit this to another micro:bit which both display the temperature and change the colour of a micro:pixel from blue to red depending on temperature. There is also a range test that runs at the end of the video to show real-world radio range.
