The first "wireless" control I had was the handheld battery powered one that came with the car. But since I wanted it controlled through the PC, I had two options:
- hack the handheld controller so I could use the existing radio control from the arduino.
- hack the car's controller, instruct it from the arduino, and get commands to the car somehow.
The second one required me to have the arduino and xbees, but they hadn't arrived, and it turned out to be dead easy to drive the handheld controller; I just had to pull a line from 5V to ground to imitate a button press. Easier than having to wire a transistor for each button to send the 9V from the battery.

The controller plugged into the breadboard. |
I also didn't have a wireless camera, but since I had a PC-controlled car, I had to try it out! I blutacked a cheap toy webcam to the car and could drive it about 5m with some USB extensions.
