Earlier this year I attended an Arduino workshop run by the lovely guys at Little Bird Electronics in Sydney. An Arduino board is an electronic micro processor which runs off a USB connection from your computer. It handles digital/analogue input/output. In English, it allows you to create your own cool robotic gadgets without having to be a electronics genius.
For example, connect a light sensor to the board, and it will send light readings back to the computer. It can even process these readings itself, and then send a message back to another connected component on the Arduino (like a motor, and an LED display).
This week I fiddled with a potentiometer (pot, or a type of dial you can turn) and fed the values real-time into Flash. Using a small program to write the pot values to serial, Flash was able to pick them up through a proxy. I could then use these values to change the properties of an object on the stage. The most effective result came from changing a shape’s (in this case a circle) alpha value as the pot was turned. It was a really good test to see how well Flash handled the incoming data. I’ll need to tweak the read speed a little to get a faster response before I move into one of my planned projects.
