Is there anything that says maker quite like blinking LEDs? But, what if you could make LEDs do more than blink? What if you want them to fade in and out, or gently blend between different colours? We’re going to look at how to do this using CircuitPython and the LED_Animations library. This should work on any CircuitPython board with either WS2812B (NeoPixel) or APA102 (DotStar) LEDs. However, we’ve tested it out with Raspberry Pi Pico and WS2812Bs.
The project uses CircuitPython to give nice effects.

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.
