Another lock for box or chest
cults3d
Remix from my first lock project. It is a new lock with a rack and toothed wheel driven by a sg90 servomotor. I used a micro: bit card but of course another microcontroller can be used. For this project, i used 4 potentiometers which divide the supply voltage into 10 parts (0 -> 9). The voltage of each potentiometer is measured on an analog input of the micro: bit card. The 0000 combination closes the lock, the programmed combination opens it. Created for an escapegame micro:bit program link : https://makecode.microbit.org/_FqTJkp2LyfCr
