Nice video but guess what happens at a birthday party then disco 🤣

Detailed working : - Working of a clap switch Working of a Clap switch: - 1)Condenser microphone takes i/p as sound of clap and gives electrical o/p. This o/p though is very small. Hence, we need an op amp. to amplify this electrical o/p. 2)Here, o/p of condenser microphone is given to the 2nd pin of IC 741. Therefore, it acts as inverting op amp. Amplified o/p is generated at pin6 of the IC. 3)The amplified o/p is then given to IC 4017. IC 4017 is a decade counter IC. Means it can count 10 numbers or 10 i/p. 4)Pin configuration of IC 4017: - In IC 4017, pin no. 14 is a clock i/p pin. pin no. 1,2,3,4,5,6,7 and pin no. 9,10,11 are o/p pins. Pin 13 is clock enable pin. Pin 12 is a carry out and pin 15 is a reset. Pin 16 is +Vcc and pin 8 is ground. 5)Working of IC 4017: - To work the IC i/p must be given to pin 14 of the IC. And pin 13 must be grounded to enable the counting. Pin no. 12 also must be grounded since carry o/p is not used. The counter increases with one for every rising clock pulse and enables its 10 o/p one at a time. After the counter reaches 9, it starts again. When the 1st i/p is given to the IC, 3rd pin i.e., Q0 gives high o/p. When 2nd i/p is given, 2nd pin i.e., Q1 gives high o/p. When 3rd i/p is given, 4th pin i.e., Q2 gives high o/p. And enables it's all 10 o/p one by one. But when Reset (pin 15) is connected to any of the o/p, it counts till that o/p only and resets the whole IC. Here, pin 15 is connected to pin 4 (Q2). So, after 3rd i/p given, instead of giving high o/p at pin 4 (Q4), it resets itself and starts again from Q0. And hence o/p keeps switching between pin 2 and 3 (Q1 and Q0). 6)Now, this o/p generated across pin 2 and 3 can be used as switch. From pin 3, and LED is connected and from pin 2, o/p is given to relay to control the bulb. But, o/p generated across pin 2 is not sufficient for relay to act as a switch. Hence, a transistor is used to amplify the o/p. Here, a NPN transistor is used. When o/p from 2nd pin of IC 4017 is given to base of the transistor, voltage is generated across base and emitter, and transistor is in ON state. When o/p is generated across 3rd pin of IC 4017, 2nd pin gives low o/p and hence transistor is in OFF state. 7)Now, this o/p generated from the transistor is given to the relay. Relay is a mechanical switch in which a coil is used to operate the switch. When voltage is generated across the relay (i.e., when transistor is in ON state) coil produces magnetic field and attracts the magnet of the switch and closes the switch (NC). When, current stops flowing through the magnetic field (i.e., when transistor is in OFF state) is coil loses the magnetic field and switch turns back off (NO). This switch can be used to switch ON/OFF the AC supply which is given to the bulb. When the current passes through the coil, the coil gets charged. When current switches OFF, the coil loses its magnetic field and produces back emf. This back emf can damage the entire circuit. Hence, a diode is used in reverse bias to stop the back emf. This is how clap switch takes the i/p from a microphone and uses it to control a bulb, a fan, a radio, or any electrical device which works on AC. Make sure to like if u find this helpful 😊

اويلي يابة... العدة والغراض مالته الا يموتن😍

El problema es que tengo un vecino dedicado al espectáculo y la gente aplaude mucho. Ya me han fundido varios focos con este circuito.

Bro, i have made as per your given circuit in the description for my phy project, but, unfortunately, when i connect the battery, if red led glows, then green led will on when clapped. But once green led is on, the red led cannot be oned again by clapping. Can you please help me with any common mistakes nd all?

If you explained it how it works. It would be fantastic

Sir this is active low or active high pin

Thank u for this video ,I am searching this type of simple circuit since long time....Keep it up👍

Sir can you explain the working principle Of this circuit

شكرا لك احسنت thanke you good. ♡♡♡

well done , very excellent you have left to describe 7pin IC value.

What are the names of the instruments given to do the experiment

Muito bom mesmo muito interessante de mais da conta valeu

so did he program the controller that he put? I thought you always need to program them, by using arduino or something else maybe...

Thanks for this project idea 💡💡 nice 🙂

Damn He Really Does Know How To Clap

Could you give me some advice for electronic beginner pls? Where did you get the container for components? Thank you.

Nice build. You could also have used the 4013 dual D Type Latch in Toggle mode

Buth acha project bunaya ap ne well done

I try this. It is my science project for science fair in my college thank you

Hi sir how to connect 1k variable resistor in this circuit diagram it has 3pin....?

Vera level 👏👏👏👏

Plot twist: Book fall from the table bulb 💡 turns on Mosquito in the room bulb is on blinking mode

This looks like magic..

Which components do you use????

Nice one,thanks.

Nice video sir... Had to make a few modifications, but its working perfectly.

I have a 6v Relay .. can i use a voltage divider in the relays input side to drop 3 v accross the register?

Sir please mention name with each apparatus. Thank you

Sir pls tell the connections in pcb board how can we understand .....

Sir plzz tell me in which direction i would solder components because i am bignner

Nice Video, very helpful

Sir can you send the block diagram of this project

What about other sounds like a shut the door? How did you filtr similar noices?

How many ac current at the relay on pcb will flow? because got 240vac go through the pcb board to connected with terminal block. the current will limited because of pcb?

Selalu yg terbaik, bisakah untuk memakai lampu LHE

Sir ,in first process (without light bulb) there is any requirement of relay. if I will connect without relay , the circuit Will working or not?

Super bro, this is used for my science fair project

Very clear vedio....tha nks

Do you have the methods how todo on the board with the resistors and etc?

So nice

Chala bagundi ❤🎉

I wanna know if we can connect the clap switch to the bulb for longer time..as usual how we use at home like continuous for 5-6 hrs..plz reply

Please clear followings droughts 1)The variable resistance is of 1K or 10K. Circuit diagram in Video says it will be 1K where attached diagram says it will 10K. 2) Same is with the resistance R1. Is it of 1K or 10K? 3) 22K is used in both circuit diagram but it is neither mentioned in the video nor in the list of items.

Bro is it possible to use 5v relay and 10k variable resistor...pls rply bro

How did you take input sir . And variable resistor third mid terminal where you was connected

Where Did You Buy That Resisters And Transisters

Sir toda explain bhe kar dete to Accha hota...

if circuit work with mic , i think relay will damage because it don't detect clap , if have big sound is relay will on/off sorry for my english

......i hope i would make this project sir bcz i show me one project based on ic so I think this is good..👍

Wowww

Really it is good

I want to know the materials used in this can u plzzzz say the name of the materials

Please keep the reply how the circuit makes connections on the back of the pcb board I have not understand it

Çok güzel bir devre

Bro can i know why it is working only for clap sounds... Is it? also work for any sound... Can you please suggest solution... Thank you

Don't use filament bulb it will gon easily dew to flickering......use CFL

Very nice video sir ji

Achha. #the kafle talk show.

Super bhai

What are those things u r using... Doesn't they have any names☹️

Ic 4017 ko (+vcc) kahan se mil raha hai. ic 4017 ke jis pin se out put liya hai uski bari to 10 clap ke bad hi aati hai

Circuit diagram is not available .could you give me the circuit diagram link or the correct circuit diagram. I really need it for my project.

Hlo please reply as soon as possible I want to make this project and I have to submit it tomorrow..... Actually I want to know the joins from back side can u please send me the picture of back side that will be enough..... Pls reply as soon as possible

plz. Tell me the cost of all the things that you have used

Why should you use variable resistance

If I shell installed audio system in place of bulb it will work or not

It will be shame while doing secret work if someone clap outside. Light will be on ...sab log dhekeka...

Sir you can send me list of tool of equipment

Welldone, Say: Brain Confident... To Be A logical Man For Your Life. Like..

Do you guys other ways to melt it? Because i dont have that thing they use

sir, you didn't shown how to connect the circuit?

The project is not working. What can i do? Please reply

Circuits tar explain dorkar.. Kivabe connect korecen exaplinly arekta vedio den please

Room may kuch boat karogay to light on/off hoya

Please circulate example again And product list send me please....

Sir, can you share this ckt diagram Please sir

@viki tech please keep abstract Introduction and equipment details

Sorry, your scheme is not working ... After I see a different scheme with the project you created, there is an IC leg that is not connected ...

give the name of components you have used.

Creative... When clapping for Happy Birthday, this idea can use

sir yadi 12 v relay use kare to 12v power supply use krna padega kya

bhai agar aap ise thoda detail me sara programming krte to jada samajh aata

Bro, you have not showed how to connect the circuit.

Could we use 5W LED bulb

i like so much☺ but can you show the circut pic

Hello sir, can you please provide the source code for this project?

i really want do it but i scare when i clap my hand my whole house blow up.

Thank you 😊

Sir we can use the 12v relay instead of 9v relay? Bro where is that circuit diagram? In that link what is the process to get that ctt diagram 😢

Can i use 6v relay?

Sir where to buy this electronic components?

Nice I also have this project in my school but the circuit diagram is so blur I can't see

Do you have a online shop I think for electronic stuff

Can you please show us the connections ..we are having trouble in understanding because of its circuit complications

Nice video in Clap light

How did you connect them pls tell?

Your circuit diagram is wrong , please correct it.
