I want to take my RC car remote, which uses a potentiometer to control throttle, and connect it to an arduino in order to control the cars speed. The ardunio fits perfectly in the base of the remote.
I want to retain original functionality, however, this can be changed.
I am fairly new to electrical engineering and arduino in general.
TLDR: What would be the best way to "emulate" a potentiometer signal using an arduino that would then get sent into into the part of the remote that transmits signals?
EDIT: This is for a project on self driving vehicles. I will have a desktop PC with Java software that is grabbing images from a camera mounted on the actual car and telling the car how to react. The arduino in the base of the remote will be connected via a USB port. The android / Java part of the software is complete and I just need to get the arduino code working to tell the car "Move Left this much" and "Go forward for x seconds". This is all figured out except for that analog control.
