When you start putting a ton of RGB LEDs on a board, the price of ‘smart’ pixel LEDs like NeoPixels & DotStars starts to add up. That’s why we fancy this IS31FL3741 breakout, which has 117 RGB common-anode LEDs, each one controlled with 8-bit-per-channel PWM. At a penny or two per, we can sell this board for a reasonable price and its fully controllable over I2C – video.
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.
