Membuat LED VU meter/ display tanpa IC, transistor, dioda zener menyala seirama dengan musik

sampurasun.. Okay friends, the LED VU meter circuit is a music level indicator, so the LEDs can light up sequentially according to the rhythm of the music. When the music is low, the LEDs will dim, but when the music is turned up, the LEDs will light up brightly. This time, I used a simple circuit because it doesn't require an IC or transistor, making it easier to build. Materials: 3mm LED x 6 220 ohm 0.5W resistor x 7 IN4002 diode x 2 100uF/50V Elco x 2 jumper Thank you 🙏 I hope this is helpful.
