littleBits Projects: Build Two Classic Games with Arduino

This is part of an on-going series of posts about littleBits projects. littleBits is available in the Adafruit store – Starter Kit, Extended Kit, Deluxe Kit, Synth Kit, Arduino Module, and Arduino Starter Bundle.

Recreate classic games of the past with the littleBits Arduino module.

DIY Etch-A-Sketch

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.

littleBits_Arduino_Analog_Pong

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.

You’ll find the Arduino sketch and everything else you need on the Analog Pong project page.

Find other littleBits + Arduino projects on the littleBits project page.

New to Arduino? Check out the littleBits Arduino Starter Bundle. It’s all you need to get started programming with littleBits and the Arduino module!


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
