Jethro The steering motor (right) spins the big gear, which moves the black bar (left) back and forth repeatedly. It doesn't really matter whether the motor turns clockwise or counterclockwise; the resulting steering action alternates left, right, left, right, etc. There's no feedback to the steering mechanism, meaning I couldn't program the car to turn left, go straight, or turn right. All I could do was turn the steering back and forth for a random amount of time. A series of gears connects to the steering wheel (top), which turns as the car is steered.
