Hey friends its ron here,

This a small project on controlling D.C motor with USB pic18f4550 interface board with L293D motor controller.

A small application is controlling my pic18f4550 USB interface board with my computer, enabling me to control my board with keyboard. The output the microcontroller is given to the input of a l293d motor controller , hence enabling me to control my DC motor in ( forward / reverse ) that is Clockwise and Counter Clockwise | anti-clock (cw/ccw) direction. For more info please watch my previous post on L293d motor controller. It must give you some idea if you a complete beginner.
