I have a version of this that works perfectly just using an on-off toggle switch. I'm trying to get it to work using a normally open ,momentary push button as a "Start" and a normally open, latching push button as an "Emergency Stop". I'm missing something but I don't know what. The program compiles and uploads but never starts running. Suggestions? Thank you!
