Sound activated switch circuit

In this post we will learn how to build a simple whistle sound operated relay circuit, which can be used for switching ON/OFF a 220 V load through whistle sounds. […] The post Whistle Activated Switch Circuit appeared first on Homemade Circuit Projects.

Here is a sound activated switch circuit using LM386 IC. The circuit will activate a relay switch for a short time period when any sound is received by the microphone. The circuit can be operated with 9V to 12V DC.

This sequential sound activated switches circuit contains four relays switches at the output. The circuit will activate the relay switches one by one when sound is received. The sound can be of any type for example whistle, clap, voice etc. The microphone circuitry is quite sensitive and you can also adjust the sensitivity according to your requirement. You can connect the any appliances you want to control through the relay switches.

Sound-activated switches are designed to provide a mechanism through which one can turn on or off any electrical appliance

This is an easy to build touch activated switch circuit using a CD4011 IC which is an IC of 4000 series CMOS ICs. A relay switch is connected at the output of the circuit from which the user can control any AC or DC appliance. Operating voltage of the circuit is 9V to 12V DC.

This is a project of a sensitive clap switch circuit. A clap switch circuit is always come in the category of very interesting electronic circuits, it is also a good learning project for electronic beginners.

Bidirectional solid state relays are had to find in particular for high power switching. Here we will build one.

This stereo audio switch circuit allows that with only one switch to select one of the four stereo channels. The internal switching is made posible with
