76 eye-blasting pixels adorn the front of the baseball cap design. The small segments of flex strip connected with stranded ribbon cable and the FLORA microcontroller can hang out on the outside or inside of the cap. The circuit is powered by a 500mAh lipoly battery which is stored in the hat’s band at the back of the head.
The had displays animations based on the audio volume from the microphone, just like the Ampli-Tie. If you’re looking for a project that reacts to sound but doesn’t require (much) soldering, check it out!
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.
