A micro:bit radio communication based office coffee machine reminding system
The office coffee machine needs cleaning but it is easy to forget as you are leaving after a hard day of work. Perhaps what you need is a device near the door to remind you!
Holding both A and B sets the alert state. Button A or Button B sends a reset.
The alert currently should go off 8 hours after a reset, showing the same display as for holding down both A and B.
At the moment I just make use of https://codewith.mu/ to upload the code to the board. If anyone wants me to work out better instructions or wants to contribute better instructions, please let me know.
