If you're like me, one of the things that makes cooking kind of difficult is keeping track of time. This project makes that much less of an issue, giving you a magnetic timer that you can put just about anywhere with both visual and sound alerts to tell you when the timer is done.

This project uses the eInk display, NeoPixels, and built-in buttons of the Adafruit MagTag to make a rechargeable, programmable kitchen timer that is also magnetic. The MagTag displays the time left and then plays an alarm through the speaker and flashes the NeoPixels when the timer is done.

This project doesn't use deep sleep so keep it plugged in between uses OR you can use the on/off switch to turn it off when not in use
