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 up to which the circuit detects claps can also be adjusted.
You can also modify this circuit into a Clap On Clap Off switch by coupling the primary output of this circuit to 4017 IC. (Will make a tutorial on this soon)
Components Required:
* 555 timer IC
* 2 npn transistors (I used BC547)
* Resistors: As mentioned in the video, depending on the voltage of power supply you are using.
* Capacitor: 22uF (gives 2.5s of LED on time), 100nF (104)
* LED/Buzzer
* Breadboard
* Power Supply: (5-12)V
* Few Breadboard connectors
This channel has a lot more electronics projects & 555 timer projects. So feel free to check them.
