sir,
i am doing project in wireless survilence robot using avrcam.can anyone tell how i can get a MOTOR DRIVING SIGNAL FROM A AVRCAM CIRCUIT .it is to control the movement of robot wheels . please help me in this topic with suitable diagrams.reply immediately to this email id

Hello,
While it would be possible to drive a single motor (or two) from the AVRcam, since there are two extra i/o lines that can be used, I would suggest thinking of the AVRcam as an image processing peripheral for the system. Thus, the AVRcam would interface with a second processor board through the serial port, and the second board would be responsible for driving the motor.

That being said, the two i/o lines can be turned into outputs to drive, say, a simple NPN transistor to a relay to drive a motor. The i/o lines could be updated on each pass of the main executive loop, or some other regular interval.
