With this sound activated switch, control by sound may be very useful, not just on The circuit can work from any 5–12 VDC regulated power supply provided a.
It is a sound operated electronic switch kit by Electro Kits. It operates on a 9V battery and uses a electrets microphone. It switches on and off an.
In this article, we'll build a sound-activated switch that can be opened and closed with a double clap.
Clap switch/Sound-activated switch designed around op-amp, flip-flop and popular IC. Switch Circuit activates upon two-clap sound and stays activated until another sound triggers the circuit. This project is tested and working properly.
Abstract—Sound activated switch is designed to provide a mechanism by section 3, conclusions and future work are mentioned in section 4.
We have described a sound operated switch circuit which will switch ON the light by just CD is the master slave JK flip flop IC which work in toggle mode.
The basic idea behind this work is that an electret mic picks up sound from the The authors used a sound activated switch to turn ON the bulb by clapping the.
