LED VU Meter

RGB LED Tri-band Audio Meter Please note that this project is not yet complete. I set out to build a tri-band (low-mid-high) audio meter out of RGB LEDs, that could also be attached to a computer to upload light patterns, so the audio meter could also be a decoration when not being used along with music. The audio data would come from an electret microphone, go first into an amplifier and then into the MCU's ADC, have a fft performed for a few different frequencies, those frequencies would each be assigned a color, and finally displayed on the RGB LEDs. The LEDs would be driven by the TLC5940 grayscale LED drivers. Project Description Document (pdf) Platform: TI Designer: Donald Zeims Awards: 3rd Place 2010 MCU Challenge Code: Source Code (zip)
