This project by Paul Ameson utilizes the Arduino and BlinkM to monitor the status of your PC’s internet connection. This project, known as the PinguinoM, communicates via USB with a PC running a Python script. The Arduino board is loaded with the Communicator sketch from ThingM and changes the BlinkM according to the status communicated via the Python script. Good example for novices of the interaction between Python, Arduino and associated hardware.
Via Make.
