New Guide: Sound Reactive Sunflower Baby Crib Mobile with Bluetooth Control

Check out the latest guide from Erin St. Blaine: build a sunflower themed hanging baby crib mobile with NeoPixels and a Circuit Playground Bluefruit. The Circuit Playground’s onboard sound sensors in combination with CircuitPython’s LED Animations Library make it fun and easy to add sound reactive modes, so the mobile reacts when the baby coos, and animates along with your lullaby.

From the guide:

Make a beautiful hanging mobile with lights for your nursery. This mobile is so cute and so much fun that older kids and adults will definitely enjoy it as well.

The included sample code has around 8 different animated color modes that you can control via bluetooth using Adafruit’s free BlueFruit app. It also has a sound reactive mode, where the lights will pulse in time to music or voices in the room.

This is a fairly easy build that requires just a little bit of tight soldering on the LED strip. The sunflowers are made from craft foam and felt that you can cut by hand or with a vinyl cutting machine. This project uses just a half-meter of very high density NeoPixels, making for gorgeously buttery smooth animations.

Plus, you’ll put a Circuit Playground Bluefruit into the hands of the younger generation and start inspiring them to love animated lights from a very young age. That’s always a win, in my book.

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 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, 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.
