This video shows how to make a DIY Bluetooth Speaker with an integrated audio-reactive LED matrix. The LED matrix includes a number of different visualization modes, including several that react to the music via a microphone inside of the speaker box.

The speaker box involved a fair amount of woodworking. The outside of the box is made from rough curly maple lumber, which I milled to 3/4". The front and back panels are made from MDF.

Internally, I am using a 2x15w Dayton Audio bluetooth amplifier board for the audio, and an Arduino Mega to control a 16x16 LED matrix.

After posting this video, a similar LED matrix product (MondoBrite) was shared with me. Although I came up with it on my own, it looks like I wasn't the first to have the idea for the adjustable diffuser. This product is worth checking out if you don't want to build this from scratch: www.britefun.com
