How to make Light sensor circuit using LDR, IC 741 Op Amp | Bread board

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!
PCB Designing of this circuit : • Converting Automatic S...
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.

[@eleobo]

Thanks for sharing

[@arthjaiswal7464]

what is the use of op amp in the circuit??

[@RuttalaPrawallika]

My circuit is working in opposite...like though there is high light condition the led is still glowing.. What should i do?

[@eleobo]

You should recheck the circuit, especially the LDR and the resistor. Maybe you connected the LDR in place of the resistor.

[@DuongBui-iu6kk]

good, it's work, I did

[@amalv.a0865]

It works perfectly

Why is potentiometer used here

[@eleobo]

Visit the website. Link below in the description

[@chikchik463]

can you show the making of this in 0 pcb
please 🥺 from 1 may i have to show this to my teacher

[@shenglingyuan]

Why is it not working in mine

[@eleobo]

What's the problem? You can contact me through @ele_obo (Instagram)

[@shenglingyuan]

@@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?

[@eleobo]

@@shenglingyuan 5-9 - based on the Op Amp maximum & minimum voltage.

[@eleobo]

Minimum 6v maximum 9v

[@shrikantambat9383]

any reason
