2 in 1 Circuit || VU Meter and Battery Level Indicator || Without any IC, Transistor

Hi Friends,
Today in this project I am gonna show you that how can you make a simple 2 in 1 circuit which is very useful to us.
hair you get two common circuits on a single PCB board that is battery level indicator and VU metre.
Here we don't use any transistor, IC as well as microcontroller in this circuit, the circuit is made up off LED, Resistance and diodes.

Suggestion; In place of yellow LED I recommend you to use any other colour Light Sky Blue purple etc for more brightness.
Cmponents required;
1)10x led
2)10x 220 ohm resistor
3)10 x 4148 diode
4)2x 470 ufcapacitor
5)2x 1n4007 diode
6)PCB board
