Enthusiast Trevor Shannon has demonstrated the use of an Arduino sending data back to a PC to be used by a Processing sketch in the form of a simple rendition of an “Etch-a-sketch”. He has connected two potentiometers to the Arduino analogue inputs, whose values are relayed back to the PC and then graphed in a Processing display window. For example:
Although a simple example, it shows what is possible with Processing and an Arduino. For more information including the sketches, visit Trevor’s interesting website here. And we’re on twitter and Google+, so follow us for news and product updates as well.
