arduino-steps-a4988

Code for controlling stepper motor 42byghw811 with a4988 controller. Note I set then steps to 20 degrees:

#define STEPS 11

Each step is approx 0.55 degrees. So 0.55 x 20 = 11 steps. Used arduino uno and this schematic. For optimal results use 12 volts and 0.2 ampere. Full wiring guide here: https://circuitdigest.com/microcontroller-projects/controlling-nema-17-stepper-motor-with-arduino-and-a4988-stepper-driver-module

Code was editted from this tutorial.
