My BlinkBeepSketch robot now has motors!
To maximize precision, I chose to use stepper motors. Due to uncertainties in the open-loop system, the more the robot moves, the more it will diverge from its course.
I bought a couple of 28BYJ-48 motors, the A4988 driver, and connected them to an ESP32. Wrote a MicroPython script to toggle the STEP pin and verified that the motor works as expected.
