I'm trying to control an RC transmitter from my PC. The transmitter contained two potentiometers (one for each stick) which varies the voltage across the centre wire between approx 1.4v and 2.3v (with approx
1.9v being centre).Of the three wires to the potentiometer, it's my understanding that I can ditch one (the black one), and just a variable voltage across the other two, and it should simulate the stick movement. However, all output from the pc (for example, serial/parallel) is digital, and I've no idea how to drive something that could vary the voltage. Can anyone point me in the right direction?
Thanks,
Danny
