Hello,
I'm trying to make an toy car controlled by serial port. How can I make a robot, wire-controlled by serial port of a PDA?
I have an old R/C car. It's controlled by radio controller. The drive train is a 7.2V dc motor, and steering is controled by a coil, that I think electromagnet.
Direction and speed control is needed for motor. For coil, direction control is enough. To communicate, serial port signal process is needed.
There is some off-the-shelf circuit kits in consideration.
or Is there any kits suitable for my purpose?
Thanks,
