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

[pradeep.m]

In video u have not used diode but in circuit it is mentioned reply me please

[mtthqfm]

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

[Madhu-nwbs]

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

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.

This project I made but it is a fake😢😢😢😢

[tesfimy]

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

[philipfansworth]

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

[spenmprojects]

Sir I am want you soldiring how that's diagram please give me I don't know how you do this please you give me digram of

[sachinpandey]

Sir please mention name with each apparatus.
Thank you

[dennicnary]

Good job, bt stop using magic, some of us want to see how you are connecting

[indrajitkarmakar]

Sir can you explain the working principle
Of this circuit

[xtdeadly]

Why are you making fool it is not working pls don't try this I tried everything in this

[Ryuk-apples]

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

[karthikuk]

Sir this is active low or active high pin

[yourchoice]

Diode is compaalsory in this project please tell. 🙏🙏🙏

[praveenkumar-vxkw]

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

[MukeshMukesh-wbrd]

Bro I done all but it's no working only red led glowing

[mohammadtaj]

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