NeoPixel Heart
In this project we’re building an LED heart with NeoPixels. This uses Black LED acrylic to diffuse the NeoPixels inside a 3D printed case. The heart is made from pieces of strips that are daisy chained to create a custom matrix.
3D Printed Case
The ItsyBitsy nRF52840 and 500mah lipo battery are housed in a separate 3D printed case. With a lipo backpack, you can recharge the battery over USB. We think this case will work nicely for your next wearable project. A button lets you trigger a reset, so you can easily update the firmware.
BLE with ItsyBitsy
You can change the colors of the LEDs using the Adafruit BLE Connect app for iOS or Android. You can also trigger LED animations like the classic Paint your Dragon rainbow swirl. With the ItsyBitsy nRF52840, you can easily add BLE to your wearable projects.
