How to make the laser light

[@keithwatkins1728]

Please make one where the alarm stays on until you reset it.

[@priyanshutiwari7848]

Its simple to do so if you use your mind, create it by your own, hint : just use a 5v dc motor instead of buzzer and use it as key of buzzer.

[@keithwatkins1728]

@@priyanshutiwari7848 unfortunately this does not make any sense to me why would a motor keep going where the buzzer stops when the person breaks the beam and turns away he buzzer stops if it is replaced by a motor the motor will react the same as the buzzer it is simple my mind tells me you do not understand that the buzzer must keep on going until you reset the system otherwise the intruder will still be able to get to you if he ran through it it would give a quick beep and you would not have heard it criminals are not stupid.

@@keithwatkins1728 Bro, I can't explain my idea by words but i know how to do, and I have done it , it's working totally wonderful✌️❤️. I have used motor as switch for buzzer and until I go and reset from motor buzzer keeps buzzing 🤘

[@keithwatkins1728]

Mr Tiwari I did not say anything about a motor When you put your hand in front of the beam the buzzer starts beeping if you take your hand away the buzzer stops if your hand was an intruder (murderer) and passed the beam quickly the buzzer would only make one quick beep if you were sleeping you would not have heard the buzzer and you could have been murdered. I think the buzzer must lock and stay on until you wake up see that you are safe and reset your alarm (switch it back on) for example your alarm clock does not make one beep it keeps on beeping till you reset it, its simple my mind tells me you do not know what i am trying to explain if done correctly it could save lives. Its a matter of a incorporating a latch to keep the buzzer on and a switch to reset your alarm unfortunately i am too dumb and you have the electronic skills to be able to do this. I hope this makes sense to you

[@keithwatkins1728]

@@priyanshutiwari7848 There is no motor involved it is your battery that sends volts to your infrared light that switches on your LDR when any object comes between your light and LDR it switches on your buzzer now your light must not come back on until you reset a button so that the buzzer will keep going and when you reset your button the light will switch your LDR back on yours system has reset. All alarms work this way. I hope this makes sense.

150 ohm ki jgha aur kon sa use kar sakte hai please sir bataiye

[@KMCelectronics]

100 ohm to 220 ohm ki bich koi bhi ek use kar sakte ho, Thankyou.

We can use 1k resister

[@gbemisoladasilva2947]

Please I'm a JETS club student in Nigeria. Please where can I get all these items so we can begin to work on our projects and I'm also the president.

[@markancajas6597]

wow its like a dark sensor circuit

what resister used in laser light

cant we use another npn transistor

[@moblog8554]

if i change the battery with 5v adapter, will it still work?

[@KMCelectronics]

Yes you can.

[@moblog8554]

@@KMCelectronics I still have some questions, I hope you can help me 1. I have a DC 3-24v buzzer, can it be used? 2. if I don't want to use a led, then the component I don't use is a LED and a resistor of 150 ohm? 3.how many watts of resistor do you use? 4. With a 5v adapter, are there any components that need to be replaced?

[@TheGamingWorld-tr9fm]

Can we use in 220 V but how...????

You have to use many different things...

[@AshishKumar-hi1wv]

can i get report of this project?

[@sumersingh9482]

Sir Yeh BC 547 transistor npn hai yaa pnp hai

[@KMCelectronics]

BC547 is a NPN transistor

[@tathagatkumar1681]

Sir beap sound ke badle me koi voice set kar sakte h kya

[@phyonergeneration462]

how if we use 12v vcc?
