Sound Operated Switch - engineersgarage.com We have described a sound operated switch circuit which will switch ON the light by just listening your clap sound. Another advantage of this circuit is that you cannot get any electrical shock as we did not have to use any mechanical switch. The circuit is based on two IC: operational amplifier LM741 and JK flip-flop based CD 4027. Sound Activated Lights Circuit - ElectroSchematics.com
Light Activated Switch Circuit Working with Applications Jul 11, 2014 · There are different types of light sensors available, but for better efficiency of the system, LDR (Light Dependent Resistor) is used as sensor light switch in this light activated switch kit. The LDR sensor has some special features as it changes its resistance with the change in the daylight intensity.

The sensitivity or Range up to which the circuit detects claps
Elenco Sound Activated Switch Soldering Kit [ SOLDERING Hone your soldering techniques on Elenco's Sound Activated Switch Soldering Kit. Just clap your hands together twice and watch the Sound Activated Switch turn on the light emitting diode (LED). Clap twice more and watch the LED turn off. A one-shot, or monostable multivibrator, is a circuit that, once triggered, will switch its output logic level. Sound Activated Switch - Relay - Electronics-Lab This project is a sound activated switch. Description. Clap switch/Sound-activated switch designed around op-amp, flip-flop and popular 555 IC. Switch avoids false triggering by using 2-clap sound. Clapping sound is received by a microphone, the microphone changes the sound wave to electrical wave which is further amplified by op-amp. Automatic Room Lights using PIR Sensor and Relay: Circuit Diagram This automatic staircase light circuit can be easily explained. Whenever PIR sensor detects any body movement, its OUTPUT pin becomes HIGH, which applies the triggering voltage to the base of the transistor, transistor get ON, and current started flowing through the coil.
This circuit employs some very simple and cheap circuitry, and a simple program. It is relatively easy to make a hardware only clap on/off circuit, but I wanted to create a circuit that required two claps to switch on, and two claps to switch off.

This video shows how to use KY-038 Sound Sensor using Arduino. It also shows how you can control LED by clap with the help of Arduino and Sound Sensor. We have shown only to control LED, but by using the same concept you can control any electronic device.
Library Reference. You can read the raw analog value from the amplified microphone with CircuitPlayground.soundSensor() this will give you just a value from between -1023 and 1023 where the default 'quiet' reading is 0.
