Burger Bot modifed to have 3 range sensors (left front right)so that it can follow a maze. It uses left and right to avoid going into a wall, when front range is less than a fixed amount it should turn right.
It uses a Pico Lipo, pico motor shim and two motors with encoders
The code "used" to work and then I started to tidy it by puttimg the logic into functions it stopped reading the encoders . at the moment I am confused as to what is happening. could be it is running out of memory, stack?
