NeoPixel LED Heart Necklace

https://youtu.be/PKWkEB1s5Ik In this project, we're building an LED heart with NeoPixels. Black LED acrylic is used to diffuse the NeoPixels inside a 3D printed case, creating a custom matrix made from pieces of strips that are daisy chained together. 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 through a button that triggers reset to easily update the firmware. You can change the colors of the LEDs using the Adafruit BLE connect app for iOS or android, as well as trigger LED animations like the classic paint your dragon rainbow swirl. The ItsyBitsy nRF52840 makes it easy to add BLE to wearable projects.
