Control Large DC Gearmotors with PWM & Arduino

Controling DC Gearmotors with PWM

Pulse Width Modulation, or PWM, is an excellent method of controlling DC motors, however controlling large gearmotors can be expensive and difficult – but it doesn’t have to be.

Today I will introduce you to an inexpensive yet powerful H-Bridge motor driver, the Cytron MD10C.

In addition, we will see how altering the PWM frequency can improve performance tremendously.
