Sound Reactive RGB LED strip with ESP8266 with screen reactive

DIY cheap and amazing screen, sound reactive and ambient light LED stip with Node MCU and Ws2811 Led Chain or strip

As everyone wants to make there room creative than others, one thing which comes under the main factor is lighting. Now a days lighting became a decorative mandatory thing for every homes, restaurants and offices. Mainly for gamers and tech lovers RGB lighting is their love. So taking that into consideration we came up with new creative sound or music sensitive LED lighting which reacts with sound on your PC or Laptop. This has an ambient light feature with amazing colors.

Advanced version: DIY Smart LED strip with Sound reactive effects using ESP8266 ESP32 WiFi

BONUS: This project also includes an amazing screen responsive RGB LED lighting in which our LED light will change according to the screen colors and intensity of the screen areas. Then why late lets get started with required components.

Required components:

  • 1 X Node MCU(ESP8266) or you can use Arduino UNO or nano

nodemcu development board

  • 1 X RGB Neopixel Led strip WS2811 or WS2812b
  • 5v power supply for Nodemcu and led strip
  • Cables for connectivity (USB cable to connect to pc or laptop), (Small wires for circuit)

Circuit Diagram:

This is a very simple circuit ever where you need only 3 wires to connect the led strip to the nodemcu. Connect the wires as shown below.
