My RC car controller (transmitter) has only 4 buttons (left wheel forward /backward, same for right)
I want to implement a joystick using Arduino.
The Arduino will use PWM on the transmitter circuit, and will use four transistors as emulated button. (When I activate the transistor, the transmitter will think the button is activated.)
- Do you think it's possible?
- Do you think it is safe for the transmitter ?
- Is arduino pwm to fast for the transmitter? do I have to make my own slower version of PWM?
Here are some photo of the transmitter:
