CIRCUIT

The circuit for this project is easy, all you need to do it connect the micro:bit to the battery pack (Or micro USB) and you're done! This battery pack has two 1.5V AAA batteries in series. When batteries are in series the voltages add together. These two 1.5V batteries supply the micro:bit with the necessary 3V it needs to run.

ASSEMBLING THE WATCH

If you already made the light up badge, the pouch made to hold the micro:bit works perfectly to create this watch. To make is a strap to wear the micro:bit on your wrist check out the tutorial video.

If you haven't made the light up badge project yet, please visit that tutorial here for instructions on how to make a pocket for the micro:bit and the battery.

Once you're done making your watch, go ahead and decorate it to make it look more unique!
