Description

LED color effects reacting on sound.

 

Contains 3 channels - red/green/blue each corresponding to low/middle/high frequencies
and one additional channel which switched on white light when no sound present on input.

 

You need to connect chain of LEDs of corresponding color to each channel.

Current-setting resistors for LEDs already present on board.

 

Use external variable resistors to adjust threshold of each channel.

Scheme contains amplifier of input signal with separate level regulator.

Expect on input sound from usual linear input.

 

Sorry for BOM - used ex-Soviet parts
