Circuit description:

KA2284 is an built-in circuit used for 5-point LED degree indication. Input completely different voltages, you’ll be able to output completely different lighting states of 5 LEDs, and the LEDs will activate and off in sequence. The variety of LED lights is often used as an indicator of amplifier output or ambient sound degree, that’s, the louder the sound, the extra LED lights up, the smaller the sound, and the much less LED lights up.

This circuit consists of two elements: a transistor amplification circuit and a degree indication circuit. The microphone sends the acquired sound by means of C3 to the transistor Q1 for amplification after which to the sign enter terminal (8 pins) of KA2284. KA2284 drives 5 units of sunshine emitting diodes to show on and off. The circuit energy provide is 12V, and R1-R5 is the present limiting resistor of the LED, with each 5 LED linked in collection. The left and proper sides of the glasses are mirrored with 5 units of sunshine emitting diodes. Adjusting RP1 can modify the sound sensing sensitivity.
