Ever wondered what your Arduino does? Use this monitor to see the values the Arduino works with and the check for own outputs.
Download the sources from github. Install Python 2. Install PySerial.
Run the ArduinoMonitor.pyw in the folder ArduinoMonitor_py. It checks for Arduinos connected.
Now whenever your arduino prints a line like
value=4 or pin0 = 25
the monitor updates the statistics.
There is an example program that outputs the values of all pins of the Arduino located in the folder ArduinoMonitor_ino.
