Door security alarm system

It would be useful to modify this device a bit. Constantly broadcasting signals will drain this battery quite quickly. Maybe not in a week. Adding a photovoltaic panel and replacing the battery with a laptop battery will extend the working cycle. In addition, another mechanism for switching on the voltage can be constructed in order to save energy.

Great work bro

Hi Guys. I've been looking at the amazing footage of you guys building projects, Ive learnt two things so far. First there do seem to be teaching videos of `how to construct you`re own` showing extream detail. (for you to learn). Then there are the other videos of teaching with the teachers showing off their skill & leaving out parts of circuitry that must be included. one such video shows a teen building a led qube- he shows the prep & construction of led qube...Yeah great, then comes da board, to begin with its follow easy. then he starts to show off by putting in jumpers that he don't mention nor nothing about the soldered tracks he`s soldered & that he`s forgotten to mention. Why this article? I totally hate show-off`s in electronics, they are a danger & think they know it all Martin Ben

Hello, thank you for the clip. I had a question. How can I make a circuit that warns when we put our hands forward?

[@indianrailnature5365]

Good project

Hello, thank you for the clip.

[@allabakshallabaksh2216]

Can we reduce the sound in the sensor

[@AkshayramJakka]

BDO can you give me circuit diagram

[@damandeepsingh9317]

Bro can I get this system's report please....

[@HemasriPodakanti-fv6bo]

Bro can we use this with 1k ohms

[@indianrailnature5365]

Nice pic sir

[@hasarapabodhi6909]

good

[@elenaherminigildo2729]

Can I replace the photodiode with normal LED light?

[@ben4518]

Try it your self to find that was, but in my theory, no, because they would cost just as much.Remember leds were only meant to shine light. technology has updated them to perform as a photo led fascinating that

[@vibhakumari6114]

Video me buzzer sound hi nhi kr rha h

[@Dhafa239]

what is the name of the patch?

[@Dhafa239]

Itu tempelannya namanya apa?

[@manirurufai1915]

Hi

[@vedavatiutpat8786]

Why this is not working..please tell me

[@creativeelectrician9714]

100 oms no 120oms support this desing

[@rockymandal5380]

No, --390 ohm is the best because lR led is 2v

[@ska1993]

Three terminal ir receiver is ok

[@vedavatiutpat8786]

This is not working

[@arachariya3646]

No bro it will work💯
