This music visualizer project combines two of my favorite things, Arduino’s & BlinkM’s, with another one of my favorite things, music! In the video above, all the BlinkM’s are mapped to display the same value, but they can be controlled individually with some modifications. Check out the link for complete build instructions and the Arduino source code. [via arduino.cc]
This project demonstrates using an Arduino, a LM386N opamp circuit and multiple BlinkM LED units to create an audio visualization device. The audio is not pass-through so it requires a dedicated mono input. In the video demo, the Arduino enclosure is connected to the tape-out of a DX052 mixer and powered by USB by my previous DX052 power hack.
