I'm trying to make a small project with 2 Arduinos, both would be controlled wirelessly.
One arduino would be the "controller" with a simple joystick on it, but would need to transmit the potentiometer values to the second Arduino which would be connected to the receiver and would be controlling 2 motors, using PWM for speed control.
Ideally I would like to use RF or something similar to it, because I have never used it before, and would like to learn it, and because it is SO much cheaper to use. However, I was reading some about it, and a few problems seem to arise with those: 1) Interference out the wazoo. 2) Would they be able to support PWM, very accurately?
Range is not a very big issue, it will all be indoors, within 200 or less feet.
Will I be able to use some RF things, or do I need to buy 2 XBee shields? :(
