  Hello Element 14! In this blog post, I’ll be discussing how to control brushed DC motors. For this project I have two goals: 1. Direction control using an h bridge. 2. Speed control using PWM.   H-Bridge An h bridge is a type of electronic circuit that allows you to apply voltage to a load in either direction. As you may know, motors will rotate in a different direction depending on the polarity so, an h bridge is perfect for changing the direction of my motor. Here i ...
