clap operated fan speed control

Here is the circuit of clap-operated remote control fans is used to control not only switching properties but also control speed of fan. The main advantage of clap operated remote control for fan is, it can control up to ten-step speeds of fan where normally a fan has three to five step speeds.
Circuit description clap operated remote control for fan
This entire circuit clap operated remote control for fan is divided into four major section i.e. sound-operated trigger pulse generator, clock pulse generator, cloc ....etc

Clap Switch
Sound operated switch using a simple transistor circuit
The operation is simple. Clap and the lamp turns on. Clap again and it turns off.
The electret microphone picks up the sound of your claps, coughs, and the sound of that book knocked off the table. It produces a small electrical signal which is amplified by the succeeding transistor stage. Two transistors cross connected as a bistable multivibrator change state at each signal. One of these transistors drives a heavier transistor which controls a lamp.

A clap switch is a fun project for beginners. It switches on and off electrical appliances with a sound of clapping hands. Today we will discuss about making a simple clap switch that operates when it detects two clapping sounds in a row. It uses an electret microphone as a transducer for converting a clapping sound into an electrical signal. The microcphone output is amplified by a transistor and is then sent to the PIC12F683 microcontroller which performs an ON/OFF switching action when valid claps are detected.

A clap switch circuit is a classic beginner s project.
Equipment can be switched on and off by just clapping your hands. Add a tiny microcontroller and you can easily build-in some more useful features.

The microcontroller in this circuit makes it a simple job to add some useful features that are not seen on other clap switch designs:

Changeover relay contacts enable the unit to be wired in conjunction with a manual changeover switch so that manual override of the switched equipment is always possible.
The unit is only responsive to a specif ....etc

CLAP SWITCH


Here s a clap switch free from false
triggering. To turn on/off any ap
pliance, you just have to clap
twice. The cir-cuit changes its output state
only when you clap twice within the set
time period. Here, you ve to clap within 3
seconds.
The clap sound sensed by condenser
microphone is amplified by transistor T1.
The amplified signal provides negative pulse
to pin 2 of IC1 and IC2, triggering both the
ICs. IC1, commonly used as a timer, is
wired here as a monost ....etc
