Re: Limit Switch Draws Tears
Make sure your limit switch is wired up between the Signal and Ground wires (and NOT Signal and Power). Signal and Ground are the only two wires you need for a simple limit switch.
Double check with a meter with the switch connected and robot powered on that the voltage across the switch changes from 0 to 5V.
I know this might be something you have already done, however I've run into many teams that try and wire the Power and Signal wires to the switch, and verify that the "switch works" by just checking whether the resistance across the switch goes to 0
