Remember how you used to spend hours spinning the two dials on your Etch-A-Sketch to create intricate (or not so intricate) pictures with a single fuzzy line? Now, with the new Arduino module, you can turn your computer screen into an Etch-a-Sketch.
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 – no art training or talent needed.
Analog Pong
If you love playing incredibly detailed, cinematic MMORPGs, you should send a thank you note to Allan Alcorn, the man who invented Pong. This deceivingly simple game captivated the world in the 1970’s and launched what would soon become a multi-billion dollar business.
Our version uses two analog sensor modules as inputs. Two dimmer switches stand in for the Pong paddle controls. The Pong paddle positions move based on the sensor values in this two player game.
