New Guide: BLE NeoPixel Hat

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.
