'bitty mood lighting' provides subtle lighting for your room. You use your BBC micro:bit as a remote control to browse through and select just the right colour to match your mood.
Our free of charge micro:bit coding tutorial will teach you how to send data from your micro:bit to a smartphone application over Bluetooth, how to use the micro:bit buttons and run code in the background so that it does not block other processing. Or you can download our micro:bit hex file if you prefer. It's also free of charge!
