Review of a 20A DC PWM Motor Speed Controller (10-60V)
This module is used to control a DC motor using a PWM (pulse width modulation) signal generated using a 555 timer IC. The module is explained. The input and output are explained, and the module is tested to control the motor and tested with current at different rates to determine how much current it can handle.
