2014 - In this project I explore the use of frequency sensors to create a visual LED spectrum. I am using an Arduino Mega microcontroller to control the 10 x 30 LED strips (300 LEDs). The biggest concern when LED projects get bigger is the power consumption. This array needs 10 amps to support a full white display. With that much current the power needed to be wired in parallel. This prevents the front loaded LEDs from burning out. In order to read the music, I am using a MSGEQ7 frequency sensor microchip. It will take audio and measure it over seven different frequency bands. I take that information, manipulate it and convert it into a digital signal that creates patterns on the LED board.
