Simple sketch for lab 7 (came out etchy) This just shows samples of a robotic arm

This sample picture just shows the elctromechanical counter on the bottom left and mechanical counter more towards top left

As already mentioned in another post this sample picture shows mechanical setup where the shafts are parallel to breadboard slots(this can cause problems adjusting spacing between gear shafts; can you see why?)

Proper aligning of shafts relative to breadboard slots is key
