If I want to implement an emergency stop button can I just connect a NO switch between ground and the RST or some other pin on the arduino?
I am using an UNO with a proto screw shield on top.
I would like to be able to hit this big red button to stop all motion and stop the spindle if something is going wrong but I would also like to be able
to resume when I fix the issue. Don't really want it to kill power as it takes a while for the power supply to actually stop after unplugging it, same for the VFD so a
software STOP would be best.
Your thoughts are all appreciated.
Thanks
