Wawa:
Limit switches should be normally closed, and open when activated.
The switch should be between pin and ground, with pull up enabled in pinMode.
Switch/ground wire should be twisted pair, to reduce motor interference pickup.Did you use potentially problematic interrupts (pin 2,3), or just polling.
Leo..
Why normally closed? Does that have to do with interference? I have them normally open (but I could reconfigure), with pinMode configured as pull up. And then I assigned interrupt handlers on event FALLING, with FALLING occurring when switch closes the circuit to the ground. Is this wrong?
And I used int for switch but polling for the potentiometer.
I only have 1 common ground for both switches. Is that bad too?
