How to start/stop the program robot by pressing the push button (input)?

You can use the wait input function to wait for an input and then wire whichever input you choose to a start button. This would require you start or play the program from the computer and then the program would not move on until a start input is received. I will also start looking into what it would take to have the teensy program monitor an input and initiate a program start but it may take a little time.

Thanks for your reply. i hope there will be a new version that can play the program by using input.
