DIY || Speaker With Music Reactive Lights

Here, I am going to show you how to make a ‘Music Reactive Sound System’ which is an Audio Amplifier with lights that react to the beats of the music.

This project is the fusion of Audio Amplifier Circuit and Music Reactive LEDs Circuit. The output of Audio Amplifier Circuit is directed as an input for Music Reactive LEDs Circuit to make the lights respond rhythmically to the music beats.

Step 1: Materials Required

To make this project, we require :

• LM 386 IC

• Transistors: BC 547

• Resistors: 1 K Ω

• Capacitor: 0.1 μF(100nF), 220 μF

• Speaker

• LEDs (2)

• Battery (4.5V & 9V) and Battery Clip

• Switch

• AUX Cable

• Wires

• PCB

• Cardboard

Major Tools required:

• Soldering Iron and Solder Wire

• Hot Glue Gun

In case you don’t possess LM386 IC, then you can use transistors to make Audio Amplifier Circuit following this video.

Step 2: Circuit Diagram

This circuit is basically the fusion of Audio Amplifier Circuit and Music Reactive LEDs Circuit.

Step 3: Step-by-Step Tutorial

This video shows step-by-step how to make this project.
