I’m trying to Hack RC of a toy car.
The car has only 2 channels, Forward/Backward & Right/Left, controlled by a B502 90deg potentiometer.
I’ve tried to control each channel with a digital potentiometer, but it only control the Forward and the Right commands.
So I’ve measured with DVM the voltage of the RC potentiometer (of the Right\Left channel) on each state (Right\Center\Left) and write it on a scheme that I’ve attached.
Someone told me I should use a SEMICONDUCTOR like this one:
But I can’t figure out how to connect it with all the system…
Can someone help me please with any idea of how to replace the RC potentiometers so I could control it from the Arduino?
