Laser Deflection Unit

This project is a laser deflection unit which can be controlled with two stepper.
Is is used to teach students how to work with microcontrollers.
There exist also a disc with a 4-quadrant photodiode.
In the git repository there is also a code which controls the laser deflection unit so that it always points to the photodiodes.

Here I uploaded only the important files for the deflection unit because this is the part the most people can use for other projects.
