Arduino Bluetooth Speaker with Reactive NeoPixel LEDs
Bluetooth speaker has now become a pretty popular household gadget that we use on a daily basis. So, for today's article, we thought to design and build our own Bluetooth Speaker. To make things a little more interesting, we have added a strip of WS2812B Neo Pixel RGB LEDs that will be used to visualize the music. In order to make the visualization more responsive, we have used colorchord - sound to light conversion tool that is developed by one of my favourite youtubers cnlohr.
