In this project, we are going to make Audio Controlled LED Circuit using a transistor. In an audio controlled LED circuit, LEDs turn on and off according to the music. This circuit is simple and efficient, it requires a small amount of audio signal at the input, which comes from the output of the headphone socket of any audio playing devices such as mp3 player, CD …
Simple Musical LEDs Circuit Diagram
https://circuitdigest.com/electronic-circuits/simple-led-music-light
In this Simple LED Music Light Circuit, condenser mic picks up the sound signals and converts them into voltage levels. These voltage signals are further fed into R-C filter or HIGH PASS filter (R2 and C1), to eliminate the noise from the sound. Further a NPN transistor (Q1- BC547) is used to amplify the signals, from the High Pass filter.
