Weekend Project: Laser and LDR security system working prototype and circuit diagram

Here is my weekend project! Laser security system using LDR and security alaram.
visit: www.circuitmagi...
To make this working prototype I am using six components.
Below is the list of parts:
Green Laser (you can use any color of laser)
LDR (Light Dependent Resistor)
Variable Resistor
5 Volt Relay board
One Siren Light (Beacon Light)
And One 5 Volt Adapter

nice project

[@ritik.bhardwaj889]

where did you get that Siren?? it was awesome!!!

[@ajokanagachandran2403]

the siren voltage is 12V and the relay board volatge is 5V. you didn't include your main power supply.how much is your supplier voltage.

Bro ldr connection lo link ayina switch board ela bro

[@farhanansari4818]

HOW MUCH VOLTAGE BATTERY DID YOU USED

[@IAMSHAARU]

we can use any laser light? ??

[@arabiccompprograming5161]

the green laser is connected to what??

[@prashanthb441]

Laser light ke vasthundha adhi a board

I would also like to know can you please reply to the comments below

[@ngliquan8232]

may i know what type of LDR are u used?

[@tubeDude48]

Light Dependent Resistor (LDR). They change value via the amount of light that is placed on the surface.

[@mr.sandhu587]

he just made for himself

[@muditkrishnatrey2580]

ldr is not functioning!!can you tell why???

[@greenbands116]

Mudit Krishnatrey it mayb the resistor u used. Hav a look at my channel for ldr project.
