- Опубликовано: 17 авг 2024
- Welcome to our RUclips tutorial on creating a light sensor circuit using an LDR (Light Dependent Resistor) and an IC 741 Op Amp. In this video, we will guide you through the process of building a simple and effective light sensor circuit on a breadboard. This circuit can be used to detect variations in light intensity and trigger various applications based on those changes. So, let's get started!

1- LDR (Light Dependent Resistor)
2- IC 741 Op Amp
3- Breadboard
4- Resistors (220Ω, 10KΩ)
5- LED (5mm)
6- Connecting wires
7- Variable Resistor (10K)
8- Power supply (9V)

Thank you, circuit works perfectly. I'm using it to enable a lighted heart, in remembrance of my brother who passed recently.
Thanks for sharing
what is the use of op amp in the circuit??
My circuit is working in opposite...like though there is high light condition the led is still glowing.. What should i do?
You should recheck the circuit, especially the LDR and the resistor. Maybe you connected the LDR in place of the resistor.
good, it's work, I did
It works perfectly
102 ke jaghe 104 liye to chalega kya
Plz share circuit diagram

is the ldr connected to positive rail or negative rail!! pls explain
Check the description and see the circuit diagram.
Plz send the circuit diagram

Why is potentiometer used here
Visit the website. Link below in the description
can you show the making of this in 0 pcb
please 🥺 from 1 may i have to show this to my teacher
Why is it not working in mine
What's the problem? You can contact me through @ele_obo (Instagram)
@@eleobo hey thanks! I did it. But do you know why we should use 5-9 volts? What was this calculation based on? And why do we should use potentiometer instead of unvaried resistor?
@@shenglingyuan 5-9 - based on the Op Amp maximum & minimum voltage.
Minimum 6v maximum 9v
any reason
Why it is not working sir

Where is circuit diagram? I skipped the video.
Check the description
Sir Please tell me
This explanation send me pls sir 💖
Can you please add circuit diagram pdf in description
