LED Toothbrush Timer

My child hates brushing his teeth and therefore usually brushes very briefly so that he can finish faster. We all know that's not the idea behind it and it's probably similar for your children. That's why I designed this timer, which shows the time with colorful LEDs and rewards you with a rainbow at the end. It requires some electronics inside to work. You can find the exact parts list and the code for the microcontroller on GitHub: https://github.com/hellodosi/Toothbush-Timer The timer is easy to use: Just a switch to turn it on and off, and a button to start/pause/reset.It can also be charged via USB-C and used wirelessly with a rechargeable battery.The Arduino Nano can also be reprogrammed after assembly via the mini-USB interface.
