Description

In this project, we implemented the music visualizer along with the fountain. One mbed will be playing the music stored in the SD card, while the other mbed will be performing the simplified analog analysis for the music. The result of the analysis will be displayed on the Neo-pixel 8x8 LED Matrix. And the motor will start pumping water when the magnitude of the sound wave reach a certain level.

The general layout and the schematic is shown below.
