Our first test with Arudino and Processing went really well. The whole idea was to make a proof of concept that our art machine was technically plausible. We knew that beforehand of course, but we had to do it for ourselves. We tested the data flow from an analog switch to a digital input on the Arduino, over the serial/USB connection and finally to the Processing where we take that first analog input from the switch and use it to produce on-screen graphics. Three switches were also used to power on the corresponding LEDs and this was controlled with Arduino directly. One of the things we also wanted to test was the simultaneous input from the switches. Each switch generated it’s own circle in Processing. The longer the switch was pressed the circle grew bigger and more transparent.
