Use two dimmers to draw on your computer screen, just like an Etch-a-Sketch.
*To complete this exercise, you will need to download the Arduino software. You will also need to download Processing to run the Processing sketch.The two dimmers send analog data into the Arduino and output serial data to Processing, a programming language that lets you control visual information on your computer. By moving the dimmers, you control movement on your screen and can draw lines.
