sound activated LED kit 1 BuildCircuitCOM Circuit Diagram 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 LEDโฆ
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 Activated LED Using LM386 Audio Amplifier IC Circuit Diagram
Common Issues and Solutions. If your Arduino Sound Sensor isn't working, try this: LED not responding: Ensure the LED is correctly placed according to its polarity and that all connections are secure.; No reaction to sound: Adjust the sensitivity of the sound sensor, if possible, or check the connections to pin 2.; Conclusion. You now have a sound-activated LED switch!
The IC can likewise be utilized to make a good-quality sound detector or sensor circuit. The circuit will blink an LED on any sound like a whistle, clap, human voice, sound system, or cellphone ring when the circuit is close to the mobile phone.

How To Make Sound Activated Multicolor LED Lights Without Power Circuit Diagram
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. 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.
