These are the last two builds my STEAM program did before I retire this year. I want to thank Pete for the technical help with these Sabertooth motor controllers. His Motherbox writeup was invaluable. The first one is for a LEAP preschool program in my county. It uses an analog joystick with potentiometer speed control wired directly to the saber tooth and ramp up and down adjusted in the software.
The second build was for a young lady named Ezra who has CDKL5 deficiency disorder. Her parents requested button control. We followed the Motherbox design except for the addition of a reverse cutoff switch, and a second control pad for parents with a selector switch.
