The concrete results may seem super sci-fi, but on a particulate level, this is just electrons and stuff moving around and rechaining. (If anything is spooky about this technology, it’s how everything deep down is just dots stuck together with wiggles.) The microbes are in an enclosed environment with water and temperature control they need, and carbon dioxide is piped in. The microbes eat the hydrogen in the air and grow healthy and reproduce.
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.
