LED animations with CircuitPython #NeoPixels #CircuitPython @HackSpaceMag « Adafruit Industries – Makers, hackers, artists, designers and engineers!


HackSpace magazine issue 51 demonstrates using NeoPixels for LED animations.

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.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

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.
