Hiya.
Hoping someone can give me some advice. I have swapped a potentiometer on a pwm controller with a hall effect throttle pedal on a kids electric car build (I flipped the magnet in the pedal so it outputs the way the pwm is expecting)
The problem I am having is that the minimum output the throttle gives is 0.8v which makes the motor run at 17% load constantly, as opposed to the pot which can go all the way to 0v. I can't think of a simple way to reduce the voltage at zero throttle, but maintain the full voltage at full throttle (as this is already only 4.2v max, as opposed to the pots 5v max).
