1. CLAP SWITCH

2. INTRODUCTION
It is a switch which switches on/off any
electrical circuit by the sound of the clap.
Electric microphone picks up the sound of
your clap, and produces a small electrical
signal which is amplified by the succeeding
transistor. The two transistor change state at
each signal.

3. COMPONENTS
 Resistors
 Capacitors
 LED
 Mic
 555
Timer
 Transistor (BJT)
 LDR

4. CIRCUIT DIAGRAM

5. ADVANTAGES
You can turn anything on/off from any
location, simply by clapping your hands.
 It involves mobility-impaired person.


6. DISADVANTAGES
Unnecessary disturbances may occur
 Generally seen as simpler for most use
cases to use a traditional light switch.


7. FUTURE SCOPE
We can increase the range of this equipment
by using a better Mic.
 Can use this as Remote Controller.

8. APPLICATIONS
Fan
 Motor
 Air conditioner, and etc…
 Tube light
