This device was created using the Arduino prototyping environment, potentiometers, a photoresistor and the Processing IDE. This tool interfaces with a sketching application written specifically to interface with the device. My first Arduino project !! An Etch-A-Sketch inspired drawing tool.
One potentiometer is mapped on the y-axis and the other is the x-axis, and every time the photo resistor's light is blocked the screen erases the previous drawing.
