Fabulous work...What else do we need to turn off the buzzer manually? I mean if we need the buzzer will keep buzzing eventhough the laser light resume hitting the LDR for the 2nd time and so on until we turn it off manually to make it applicable for home security. Thanks anyway, Sir.

my questions is that i have connected everything properly but still buzzer and light keep work though intensity change but why its working when laser fall on it

@emeraldgrape2222 Жыл бұрын

i need hlep the moment i put the bateery it already started buzzing and when i turn off lights it stop when i put the lase to the ldr it shines brighter and becomes louder

A normal laser can work?

@taruncariappa7467 Жыл бұрын

Very good circuit. Can u modify the circuit so that the buzzer will continue to work even after the laser beam falls back on the ldr. This could be reset with a switch

good stuff! could you change the resistor or have a variable resistor in there to allow for ambient light hence give the pthing some sensitivity do ya think??

What is the range of lazer .

@andym5195 3 жыл бұрын

depends on the laser strength

@jitk7072 5 жыл бұрын

if the laser light is on then the buzzer beeps

@komaliesguys3416 5 жыл бұрын

Even the light is on the light is glowing

@TechStudyCell 5 жыл бұрын

As I have turned off the laser so the LED is glowing. Buzzer or LED will turn off if the laser light fall on the LDR.
