Currently I'm doing a few important steps at once on the project.
The first is getting the Arduino chip to talk to the computer and give information about how much light is being received by each sensor. This coincides with writing an Arduino 'Sketch' which will interpret the voltage data coming from the chip and enable me to send it to my Tea Set patch I have built in Max/Msp. Its all proving quite challenging. I'll post a few pics of how its all looking in a few days.
