Today I am going to make a simple circuit of Mobile phone detector using LM386 IC.
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: Materials Required -
Step 2: Connect 10uf Capacitor to IC
Firstly we have to connect 10uf capacitor to the ic.
Solder +ve pin of capacitor to pin-1 of the IC and
-ve pin of capacitor to pin-8 of the IC as solder in the picture.
Step 3: Connect LED
Next connect LED.
Solder +ve leg of LED to pin-5 of the IC and
Solder -ve leg of the LED to pin-4 of the IC as you can see in the picture.
Step 4: Connect Antenna Coil
Next solder anteena coil to pin-2 of the IC as you can see in the picture.
Step 5: Connect Wires
Next solder wires for 3V battery.
Solder for +ve wire of battery to pin-6 of IC and
Solder for -ve wire of battery to pin-4 of the IC as you can see in the picture.
Step 6: Connect Battery
Now we have to connect battery to the Battery wire.
Solder +ve wire of battery to +ve of battery and
-ve wire of battery to -ve of the battery.
Step 7: Circuit Is Completed
Now our circuit is completed.
Step 8: How to Use This Circuit
Keep this circuit near to any mobile phones then we will observe that as circuit is going towards mobile phone according to that LED is glowing.
Picture - As picture shows when I put this circuit near the phone then LED is glowing.
>> This type we can make Mobile detector circuit using LM386 IC.
