Why use a PCB silkscreen when you could showcase the shiny gold metal layer? Why build a rectangular board when you could have strange and wonderful shapes? And why settle for a dull LED flasher when you could have something crazy? I went a little bit overboard with this one, and I’m unsure how to even describe it. It’s a wearable LED blinky, with some terrible (or amazing?) abuse of the PCB fabrication process, many eye-catching light displays, and careful attention to power usage to ensure long battery life. For lack of any better name, I’ll call it the Star Ring.
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.
