Thumbstick Motor Control with added POT speed control

Hi all,

I am a newbie to all this and I was hoping someone with better knowledge could help me with what I’m sure is a fairly simple task.

I have an Arduino UNO with motor control shield and I managed to get the motors running with some little analogue thumbsticks.

Even though the thumbsticks allow a certain level of motor speed control I want to introduce a potentiometer into the circuit allow over all speed control, enabling me to control the top speed on the fly.

I tried running the output signal from the thumbsticks through the POT but it didn’t behave as desired.
I managed to get the desired result by running the output to the motor through the POT but I know this will fry the POT as soon as I switch to bigger motors.

I would be very grateful in any guidance anyone can give me in this as I’m scratching my head as to the best approach.

Thanks and Best Regards,

I guess that you use the Arduino to read the joysticks? If so, then read the pot value as well, and decrease the joystick values accordingly.
