This is my first experiment with the Arduino microcontroller. It's a prototype for a future artwork that essentially acts as a primitive touchscreen device. I've used 2 PING))) Ultrasonic Range Sensors positioned at the top of my monitor. These measure the distance of any object placed in front of them. The Arduino board collects this data and passes it on to Flash via SerProxy.
