Reversible motor control for Arduino and other MCUs

in Arduino, how-to by the machinegeek | 2 comments


Nothinglabs has posted their circuit for a simple reversible motor control for use with the Arduino and other MCUs. The circuit uses two TIP120 Darlington Transistors, two 220 ohm resistors and a 12 volt DPDT relay, parts easily obtainable at any Radio Shack. This design supports PWM for variable speed control, handles loads up to 5 amps, and is controlled using just two MCU pins for “enable” and “direction”.

    Man this is lame. Did you scrape this from Hack-a-Day, or vice-versa?
