@westfw:
I am not familiar with Putty. How would this help me?
@holmes4:
I am now using an external power supply. Also, I fitted additional capacitors. Ripple is down, voltage is at 4.99V. I'm currently running the program with IMAX set to 3000. The output stopped at i = 151.
When I push the reset button or when I open the Serial Monitor, the program restarts. The output reads "Betriebsbereit" again, unless the output was interrupted. In that case, the program does not restart and I cannot open Serial Monitor again. If I try, I receive this error message (translated from German): "The serial port 'COM4' is already in use. Try shutting down other applications that might be using it." What could be the reason for that?
This is the whole text of the error message:
processing.app.SerialException: Der serielle Port 'COM4' wird bereits verwendet. Probieren Sie, andere Programme zu beenden, die ihn benutzen könnten.
