So, basically, I don't need to know where to buy parts, I need to know how to choose them and how to put them together.
I also took your advice about the RC car and found an old RC Jeep under my desk. I've removed the top half of the chassis, ripped out the circuit board, and modified the battery compartment to support the Arduino Uno. I want to connect the two motors (as far as I can tell, the front motor turns the two front wheels left and right and the back motor rotates the two back wheels) to the Arduino, but I don't really know how.
I assume I'll need to buy a Motor Shield?
Will I need some adapter cables to connect the RC motor cables to the Shield? What type of adapter cables? Or do I just pull the white plug off the cables and attach the wires directly to the Motor Shield? Is there anything else I should know about using this Jeep with the Uno?
Damn, I was afraid ripping the original board out might not have been a good idea. I don't think it's been damaged, but it won't be able to be powered by the Jeep's original batteries anymore, and it can't even reattach itself to the battery compartment because I filed that down to be nice and flat for the Uno. Anyway, here are the most high-res pictures I could get of the board, front and back. Two questions:1) If I use the original board from the Jeep to control the motors, do I not need a Motor Shield anymore?2) Will I still be able to power the original board with another type of battery?And I don't know what an IC is, but on the back of the board it says 'RX-2022B(SMD)'.
