Brushed

This Addohms Brushed DC Motor Tutorial goes into the third dimension! Using a variety of 3D models, we show you what makes a brushed DC motor, a brushed DC motor. Then, like usual, we break two simple ways to control them with a microcontroller like the Arduino. You can use a single BJT Transistor (remember those from #10?), build your own H-Bridge, or use a popular H-Bridge chip.
