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 The voltage of each potentiometer is measured on an analog input of the micro: bit card.
a switch is used to memorize the value of the 4 potentiometers.
The 0000 combination closes the lock, the memorized combination opens it.
Created for an escapegame
