2012 is not only the year of the Olympics, but also the launch of the first ever ‘Digilympics’, a twitter-powered race for sporting success where you determine the outcome. Four Lego athletes move down a physical racetrack as fans Tweet their team to move them further towards the finish line.
A Processing sketch scans the Twitter account of each country for any ‘@’ replies. Any new replies are passed to an Arduino with 4 motors attached, one for each team. The motors spin and advance each team forward in response to tweets received. An infra-red beam detects the country reaching the finishing line first and signals for the reset of a new race.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
