I am working on hacking an RC remote controller I own. What I intend to do is open it up, and tap into the potentiometers. I want to read the analog values delivered by the potentiometers, and send the signals to my PC. Essentially, I want to re-purpose it to work like a joystick with the HID USB interface. Of course, the HID interface is not necessary, but I believe it is the best way to go about this.
I am quite familiar with the AVR microcontroller family, so I initially though I could try something like V-USB with an ATMega8. At the same time, I began to think that it may become unnecessarily difficult. Is there any easier way to achieve such connectivity without breaking the bank?
