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

This Project Automatic Room Light Controller with Visitor Counter using Microcontroller is a reliable circuit that takes over the task of controlling the room lights as well us counting number of persons/ visitors in the room very accurately. When somebody enters into the room then the counter is incremented by one and the light in the room will be switched ON and when any one leaves the room then the counter is decremented by one. The light will be only switched OFF until all the persons in the room go out. The total number of persons inside t ....etc

OFFLINE EXAMINATION SYSTEM
ABSTRACTS
Offline examiner is a real time project. The project will be implemented using VB. The aim of the project is to allow teachers to conduct examinations to the students. There are many unique features in the project. The students are not allowed to go back to the previous question once they click the next question. This option is up to the teachers to decide the teachers can either enable such an option or disable the option. The teachers are also given option to set the time limit of the exam. When the stud ....etc

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
