Software – Hobbybotics Motor Controller Tester V1.0

I wrote this application to test the Hobbybotics Motor Controller.  This application controls the motor controller over the serial port by way of a micro-controller.  Take a look at the project page for more details.  You can find it here.


Project – Hobbybotics Motor Controller V1.0

I designed a basic motor controller that is robust, cost effective and able to handle high current. I wanted to take advantage of Pulse Width Modulation (PWM) to allow speed control but keep direction control as simple as possible.  Thus, I use a pair of SPDT relays for direction and a single MOSFET for PWM.  I also use optoisolation to separate digital logic from the back EMF of the motor and relay coils.  Go here to see it.
