As the number of my guitar pedals grew, the decision was clear to build a pedalboard. Then I thought, why not add some light, so I can see the knobs in the dark. And then I found out about those programmable LPD8806 strips with libraries for Arduino and Raspberry Pi. That was when things blew out of proportion… so now the result is a mixture of light organ and pedalboard. It can turn sound into light using pitch detection and sound volume with a little help from a Raspberry Pi. It features several animation modes and a Tuner, a visual metronome and more to come.
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.
