This is four arcade buttons and four smart full-color LEDs, drilled into an IKEA Antilop high chair (a spare tray is $5). The brain is a 5v Adafruit Pro Trinket, powered by four AA batteries.
The default mode is the same as the blinky my dad made for me long ago: press the red button and the red light lights up, press the green button and the green light lights up, and so on.
Holding down all the buttons at once lets you switch modes: mode two is like mode one, except each light stays on until the next one is pressed. Mode three is like a typewriter, and mode four is a step sequencer.
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.
