RC PWM Signal to Stepper Pulse Generator

RC PWM Signal to Stepper Pulse Generator

This simple Arduino compatible project reads an RC PWM signal (1000μs to 2000μs) and provides 0 to 500Hz pulse output to drive a stepper motor. Step and Direction outputs are open collector types 5V signals. Both signals can directly drive LEDs of optocoupler of stepper drivers. The...
