In this project, we’re making a light up hat with bluetooth controlled NeoPixels. We took this on our recent trip to Disney World and just floored the cast members and park goers.
This is a really fun project for folks just getting started with electronics. This guide will show you how to add a NeoPixel strip to a hat and wire up the electronics.
The Adafruit Bluefruit nRF52840 has everything you need to add BLE to your projects. You can remotely control NeoPixels using the Bluefruit LE app for iOS or Android.
In this project, we’ll use the color picker and the control pad to trigger different animations. You can also use an Apple Watch to remotely control the NeoPixels from your wrist. This can be really handy for those times you might not be able to pull out a mobile device.
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.
