How to Make AC Line Tester Using 4017 IC

Hii friend,

Today I am going to make AC Tester circuit using 4017 IC. This circuit will show AC current without touching the surface of the wire.

Let's get started,

Components required -

(1.) Battery - 9V x1

(2.) Battery clipper x1

(3.) Copper coil (Antenna)

(4.) IC - 4017 x1

(5.) Connecting wires

(6.) Buzzer x1

(7.) LED - 3V x1

This picture is the scematic of this project.

Firstly we have to connect pins of IC as pin-15, Pin-13 and pin-8 of the IC as you can see in the picture.

Next we have to connect Buzzer to the IC.

Solder +ve pin of Buzzer to Pin-9 and -ve to pin-8 of the IC as solder in the picture.

Next Solder +ve leg of LED to pin-1 and -ve to pin-8 of the IC as you can see in the picture.

Next we have to connect Antenna wire to pin-14 of the IC as solder in the picture.

Now we have to connect wires of the battery clipper.

Solder +ve wire of battery clipper to pin-16 of IC and

Solder -ve wire of battery clipper to pin-8 of the IC as connected in the picture.

Now this is the last step of this project in which we have to check the circuit.

Connect Battery to the Battery clipper and keep circuit around AC current flowing condutor then LED will glow and Buzzer will give sound.

Thank you
