Schematic diagram of an Arduino connected to an H-bridge to control a DC motor. The Arduino and switch are connected as described in the drawing above. An L293D H-bridge has been added, and is connected to as follows: Pin 1 is connected to the Arduino's digital pin 9. Pin 2 is connected to digital pin 4. Pins 3 and 6 are connected to the DC motor's two connections. Pins 4, 5, 12, and 13 are connected to ground. Pin 7 is connected to digital pin 3 on the Arduino. Pin 8 is connected to the positive terminal of a 9-volt battery. The battery's negative terminal is connected to ground. Pin 16 of the H-bridge is connected to the Arduino's +5 volt output. The rest of the H-bridge pins are unconnected.
