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,
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Take All Components As Shown Below
Step 2: Circuit Diagram
This picture is the scematic of this project.
Step 3: Short Pins of IC
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.
Step 4: Connect Buzzer
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.
Step 5: Connect LED
Next Solder +ve leg of LED to pin-1 and -ve to pin-8 of the IC as you can see in the picture.
Step 6: Connect Antenna
Next we have to connect Antenna wire to pin-14 of the IC as solder in the picture.
Step 7: Connect Battery Clipper Wire
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.
Step 8: Connect Battery
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.
