Be the 'Light' of the Party with This DIY Flashing LED Suit
If you've ever been on your way to a party and felt that your outfit just wasn't flashy enough, engineering student 'Rambo' has got just the thing for you.
His homemade LED suit lights up and dances to the beat of the music, and can even be controlled via Bluetooth.
The LEDs are controlled by an Arduino and the music is fed through MSGEQ7 chips, which break up the audio signal into 7 different voltage bands. The breadboard that controls the LEDs was designed in Eagle, which he posted here to download if you want to make your own.
Next came the "bar graph equalizer," which separates the audio and creates the different colors. After putting together the circuit, he attached the LEDs to the suit and added the Bluetooth module and it was ready to test (the pants, at least).
