Motor Controller Chip

This low cost controller chip can decode the signals from a "VEX" receiver to control up to 8 motor's H-bridges and 1 driver.

For the people who don't know what a "VEX" is. It is a company that sells robotic parts and kits. They sell a "VEX" transmitter and receiver on their site for $129.99 but you can get a "VEX" transmitter and receiver for about $20 to $30 on "Ebay" and many other places.

It can also receive commands from another microcontroller chip to control the motors. This controller chip uses 3 output pins to control a motor's H-Bridge. Two pins to control the motor's direction and one pin to control the motor's speed by using P.W.M.
