The latest is an Arduino controlled Christmas tree:
Three 50 pixel WS2812b RGB strands, multitasking three separate NeoPixel patterns from three digital output pins. This Candy Cane program is running on an Arduino TinkerKit LCD (a Leonardo clone) driving three separate 50 LED WS2812b strips. By lowering the intensity of all of the pixels (built in to the script) the entire display is powered by a 2.4A USB tablet charger through the USB input on the TinkerKit. By controlling the overall LED intensity, the onboard PTC “fuse” will not overheat nor shut down the processor.

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.
