If the people walk into the laser and it the alarm goes off, the people will know that there's a laser light security alarm system there so they will instantly back away and then they will try to run across it as fast as they can to make the buzzer goes off in as little time as possible. If the time the buzzer goes off is too short, it might not wake you up, you need a system where the buzzer goes off when someone walk into it and stay on forever until you turn it off.
brother can you share the circuit diagram it would help me in my project rn i know i am a bit late but if u made it once i guess u can make it again(im in sooo much in the need of it)
Looks good but needs an alarm and it must stay on until it wakes you up and you must reset it and check if the intruder has gone please help to modify this thanks
You did an excellent job explaining how to make this circuit! Thank you for rotating the breadboard so I could see how the pins are placed. Also, you explained the pinouts of the components very well! Thank you!
thankyou so much bro you are really a great while I saw many videos but no one define all the things they just put a song but from your video I get a great knowledge
Iam so Tankfull to you Bro Because How many videos if I see also my circuit got failed but your video was very helpful Tank you very much 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
Hi sir. What an amazing project♥️♥️. I'm going to make it in my school. I have a doubt that is it specific that we have to place the components in a particular block of breadboard. Plz tell
Awesome. I am very new to electronics, not my profession (hobby). I have done your experiment and it turns on when it is dark. It only turned on when the obstacle was very close, practically touching the LDR. However the laser part did not seem to work since I have a laser pen like the one teachers use - maybe too weak, so I have reduced the resistance and it worked - hopefully I did not mess up something, but it worked like in your video.
Could you please provide with the circuit diagram or perhaps make one? It would be really helpful. ps. - also thanks for providing with the video. It has been of great help.
When the laser light falls on the LDR, the circuit still remains closed and the buzzer/LED still produces a sound/light. Is it something wrong with my LDR or do I need to somehow increase my LDR's sensitivity?
Hey! Just double check if you've connected everything correctly as in the video. If it still doesn't work maybe this video of mine might help you 👉ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ZIwBVln4cgQ.html I hope this was helpful :)
