Music Operating Dancing LEDs light

In this project we are going to build an amazing circuit named Music Operating Dancing LEDs You have seen the nbsp DJ lights or nbsp Disco Lights that Turn ON and OFF with music These lights run according to the length and volume of music basically these are built to sense high-intensity sounds like Bass sound So these lights follow the high pitch beats in music like drum beat sound and Turn ON and OFF according to music change You can increase and decrease the sensitivity of this circuit First of all you should build Dancing LEDs which just follow Read More

Touch On Touch Off Switch Circuit Using 555 timer

In this simple Touch lamp switch nbsp circuit we have used timer nbsp IC operated as ON and OFF nbsp By using this circuit you can turn ON and OFF a device by simply touching the Touch Plates or metal used as a sensor If the touch plates are placed at a convenient place we do not require moving from our location to turn them on and off the device The important feature of this circuit is that we will not get any electrical shock which we sometimes get while using normal switches In this simple Touch lamp switch nbsp Read More

Clap Switch : Circuit and Its Working

An electronic device that can turn off by clapping is called a clap switch It can control light appliances by users' clap action also It was invented by Stevens R Carlile and E Dale Reamer in The main advantage of this circuit or device is that it is mainly helpful for a mobility-impaired person The condenser mic is one of the main parts of the circuit that takes input clap sound based on the pitch of the clap This article gives an overview of the clap switch Electrical pulses are the desired input to the clap switch circuit What is Read More
