A Bitty Software application - https://bittysoftware.blogspot.com/
Liven up that Xmas tree! Hang a BBC micro:bit on it and use the Bitty Xmas Bauble app on your phone or tablet to make it display any one of 6 delightful LED animations and play any one of three Xmas tunes. Note that you must have the right code on your micro:bit. See below and https://bittysoftware.blogspot.com/p/faq.html
Don't worry, we recognised there's a risk of driving everyone crazy with Jingle Bells playing over and over, so you can switch off audio or the LED animations or both, all from the convenience of your smartphone.
Note that to play tunes, you need to connect some audio hardware to your micro:bit. We recommend the Kitronik MI:power board available from https://www.kitronik.co.uk/5610-mipower-board-for-the-bbc-microbit.html but if you prefer you could just connect a piezo buzzer to pin 0 and GND.
