Sound Reactive LED Strip: THERE MAY BE 9 STEPS BUT I PROMISE THIS ONE IS QUICK AND EASY!  In this Instructable I will be showing you how to create a light reactive LED system. In this clip, I used a single color LED strip, but you you can use a single LED, multiple LED…

Sound Activated LED Using LM386 Audio Amplifier IC Circuit Diagram

Create an immersive audiovisual experience with our DIY Music Reactive LED system, synchronizing aptivating light displays with the rhythm of your favorite music using Arduino. // Analog pin connected to the sound sensor 2 const int ledPins [] = Circuit Diagram. This will help you to Connect all wires. Circuit.png. Code. Code. Code.ino In this video, we are going to show you making a music activated led light circuit without mic and IC. You can make this circuit at home easily. You also can

resistance(R) = (power supply voltage - LED voltage drop) / LED current The typical recommended LED current is 20mA, our power supply voltage is 9V, and the LED voltage drop for a clear blue LED is 3.0V. This results in: (9-3)/0.020=300 ohm Of course this doesn't need to be exact, a 330 ohm resistor will work fine here. digitalRead(soundSensor); reads the digital value from the sound sensor (either 0 or 1). Serial.print() and Serial.println() print the sound sensor's value to the Serial Monitor. digitalWrite() sets the LED states: If soundValue == 1 (sound detected), all LEDs turn ON. If soundValue == 0 (no sound detected), all LEDs turn OFF.

Sound Sensor with Arduino Tutorial Circuit Diagram

As soon as the power is switched on, the microphone is powered. When it responds to sound, it emits an electrical signal. This signal is coupled by capacitor to the first transistor amplification. The amplified signals are sent to second transistor base. Second transistor drives LED to emit light. The louder the sound, the brighter the LED.
