Control Large Gearmotors with PWM & Arduino

Pulse Width Modulation (PWM) is the ideal method of controlling large DC gearmotors, but driving these motors can often be challenging and expensive. Today I will show you an inexpensive and efficient H-Bridge motor controller – the Cytron MD10C. I’ll also show you how raising the PWM frequency can make your motor controller design far […]
