✅ Led sound level indicator with your own hands!!! All genius is simple! ✅

Hello everyone In this video, you will see how to make a sound level indicator (VU Meter). But the most interesting thing is that for
this indicator does not require chips, transistors, or even a supply voltage! All genius is simple!
To make a sound level indicator, you will need to find the following details: 10 LEDs, 10 680 Ohm resistors, 9 diodes
1N4841, 2 diodes 1N4007 and two capacitors of 100 UF. Well, the process of assembling and soldering this indicator of the sound signal level
you can watch it in this video.
