tienes le diagrama y la lista de materiales ?

Sorry, no diagram. The device uses an AVR ATmega644 microcontroller. The LEDs are driven by 3x TLC5941 12bit PWM LED drivers, the audio detector is just a simple peak detector (diode + low pass filter using resistor and capacitor) circuit going into the ADC of the microcontroller.
It was only a prototype, the finished product was much different.
