This is a fun-loving project based on the Arduino platform. The project creates color light effects with sound level sense by an onboard condenser microphone. The project consists 20 x WS2812B RGB LEDs, an Atmega328 micro-controller, condenser microphone along with pre-amplifier, RCA connector, and trimmer potentiometer to direct feed audio. The project can be used in fun parties, disco parties etc. Just power the board and RGB LEDs will create different colors as per sound level. Board has the option of direct audio input or sound sense by the microphone, users may change the Arduino example code as per requirement or write their own code.
