Ways to Design Own Sound Activated Switch Circuit Diagram This project uses an LM386 audio amplifier IC with a few other components to build a simple and accurate sound-activated alarm circuit. The circuit will activate a buzzer for a few seconds when the microphone receives a sound. The sensitivity of the circuit is good and it can detect sounds of the whistle, clap or finger snap from many meters away.
Sound Activated Timer Switch Code Since the Grove Sound Sensor produces a varying voltage, we can use the microcontroller's analog-to-digital converter (ADC) to handle that voltage. So, here is a simple Seeeduino Sketch, also compatible with Arduino Uno/Nano, that reads the voltage from the sound sensor module connected to A0 which is then

The Circuit. An electret microphone is a type of condenser (capacitor) based microphone that converts sound energy to electrical energy. It is a low cost microphone that can be found in every cellphone, laptop, camera, and so on. The main component of the circuit is the electret microphone and it is used as the sound sensor.

This circuit is operating on 9-12V DC. The working of this circuit is quite simple, the main component is an audio amplifier LM386 IC. Following are the steps that you should follow to make this circuit work, Sound is received by an Electret mic which converts these sound signals into electrical signals. A tutorial on How to make a Clap Switch circuit aka Sound Triggered LED, along with detailed explanation on how the circuit works. The sensitivity or Range u
1.Just sound of clapping[the sound of striking your palms together]. 2.Use coil pins of relay,a transistor and a diode. [I also, designed a very practical sound switch with a relay that work very good.]. Have a nice day,
