I had an old radio control remote lying around my house and wanted to see if I could hook it up to the robot controller. The potentiometers for the joysticks I measured to be 4k Ohms. I know that the robot controller gives 5V, it wants 0.00005 Amps through a 100k Ohm pot. So therefore the 4k Ohm pot would need 0.2 volts to get the 0.00005 Amps. So I got a 96k Ohm resistor(which would have 4.8 V across it) and put it in between pin 1 (positive) and one end of the pot. I put pin 4 (ground) on the other end of the pot and had pin 6 (y axis) on the wiper. The thing is that the motors don't turn when the pot is adjusted. Only when the joystick is all the way down the motors twitch. When I short over the resistor it spins but I have no control(I know that is supposed to happen with such a small pot). I have no idea what is wrong? Is the pot too weak and just creating a little noise?
