i need help .who to stop servo with FSR ( forse sensor)

Hi can any one help me ineed the code to stop servo at any position when I touch the FSR

with the information you posted, the only answer you will get is: "it is simple, you just need to wire the parts correctly and then write the appropriate code"

FSRs don't react much to mere light touch, they need pressure applied.

After that it's indeed a matter of reading the FSR and when over a certain threshold, stop the servo movement (which is an odd requirement in itself: is it a continuous rotation servo or regular servo?). Or do you mean that you want to move the serve based on the pressure applied? That would make more sense.

Very easy sketch.
