Simple 12 Volt battery level circuit diagram || how to make 12 volt battery level indicator #12volt

Today I am going to make a Battery level indicator that will show the percentage of up-to 15V Battery. This circuit is very easy to make and it is very cheap.

Take All Parts As Shown Below

Parts required

(1.) Zero - PCB

(2.) LED -3V x5

(3.) Resistor 1K x5

(4.) Connecting wires

(5.) DC Power supply - upto 15V

Solder All Components in PCB

Solder all components in PCB according to this circuit diagram.

Insert all LEDs in PCB in series like circuit diagram.

Solder all wires of LEDs as solder in picture.

Now insert all resistors in pcb as inserted in the picture according to circuit diagram.

Next solder all wires of resistors as solder in picture according to circuit diagram.

Next solder voltage input wires as solder in picture according to circuit diagram.

Black wire is -ve and brown wire is +ve input DC power supply.

Now our battery level indicator circuit is ready. Now match circuit according to the circuit diagram and

Give input power supply to the circuit.

NOTE:We can give maximum 15V DC power supply to this circuit.

As in picture when I give above 13V DC input then all 5-LEDs are glowing

As in all pictures we can see the different voltages Indicate different LEDs are glowing.

As in picture 1 show when I give above 2V then one LED is glowing,

When I give above 5V then two LEDs are glowing,

when I give 10V then 3-LEDs are glowing,

When I give above 13V then All 5-LEDs are glowing.
