I am doing a science fair project relating to the Arduino Uno. I am planning on making a car or mabye an RC Car with the Uno. If anyone might have some insight that would be great! I am not asking you to do it for me just asking for mabye some cheap "motor" that can be easily powered. I would need four of them (one for each wheel.) Any help would be greatly appreciated!
Thanks,

Thrift shops are a great source for motors, wheels, RC car chassis, etc.
Grab a working R/C car, not the cheap toy ones but one you'd find in a Hobby Shop. Pull out the RC receiver and replace it with your Arduino.
Code, rinse, repeat.
To your Arduino a typical RC car "looks" like 2 servos. A throttle and Steering. Your ESC, or speed controller will supply you your 6V to power the brains and servos of the machine.
