How to develop a low-cost motor controller

This paper describes the design of low-cost DC motor controller for use by robot hobbyists. The motor controller created by this project has a profound impact on the robot hobbyist arena by creating a product that performs far beyond its expectations This is due to the fact that this motor controller will drive two independent DC motors with the same functionality found in a high-end single motor controller, and cost only $30 to build. Testing has shown that the hardware platform designed and created by this project is capable of performing all the functionality of a high-end motor controller while controlling two DC motors. The software is user-friendlier than any other motor controller currently available.
