Automatic limit switch

[Mark McLeod]

Can you better describe your application?

It sounds like a sensor problem other than a limit switch.

A spinning motor speed is usually controlled by an digital encoder sensor.

I am guessing that you want to stop something like an arm or the robot when it touches something? If you already know how to use the digital switch, then it is simply using that input to switch between the commanded signal and a stationary command. More details would be helpful.
Screenshots of what you have so far would be helpful too.

we have the digital switch. we need something in the code that makes the motor stop when it starts binding or reaches a certain amount of rotations. So far we have been sent a digital input example.
