I am trying to hack a RC controller i have. The way the controller works is that it has two potentiometers. One for the throttle and one for the steering left to right.
Instead of building my own ir transmitter I hope to just replace the two pots with an arduino board. The controller uses a 6V supply which is made up of 4 AAA batteries but I am replacing that with my own power supply. I thought i would be able to replace the two pots with a MOSFET circuit ( https://www.sparkfun.com/products/10256
). So I attached the pots to my arduino board and using the example here http://arduino.cc/en/Tutorial/AnalogInOutSerial
I read the values, and determined what i should send to back to the controller. However regardless of the PWM values i send the remote never changes its state.
Does anyone have any ideas as to what I might be missing?
