This is from a brilliant little device that I’m thoroughly enjoying right now. Well-designed, and surprisingly addictive. First person to guess this correctly gets a chumby One as a prize. As a reminder, if you want to enter a tentative guess without letting everyone else know, you can post an md5sum or a sha1sum of your guess string, and then post the source text for your hash in about a week — but remember to do that, because if you just leave a hash and fail to post your source text, I can’t judge your entry and the prize might go to someone else!
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.
