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. I ....etc [:=Read Full Message Here=:]

When the intensity of sound exceeds certain intensity, the alarm is triggered and the siren begins to operate. The speaker beeps and the flasher (light) flashes. Thus the owner of the residence is alerted when an intruder comes. The functional block diagram includes -MICROPHONE -AMPLIFIER -LATCH -OSCILLATOR -FLASHER -SPEAKER a 600O unidirectional moving coil microphone is used. LM386 CMOS operational amplifier was the main component in the amplifier. It had a gain of 200. The amplifier then passes it on to the latch section of t ....etc [:=Read Full Message Here=:]

A Simple Light activated switch Description. This is the circuit diagram of a light activated switch based on National Semiconductors comparator IC LM 311 and a LDR. The circuit is based on a voltage comparator circuit wired around IC 1.The non inverting in put of IC1 is given with a reference voltage of 6V using resistors R3 and R4. The input to the inverting input will be the voltage across the LDR that is light dependent. At darkness the resistance of the LDR will be high and so do the voltage across it. At this condition the voltage ....etc [:=Read Full Message Here=:]

Abstract This paper presents the design of a clap activated switch device that will serve well in different phono-controlled applications, providing inexpensive key and at the same time flee from false triggering. This involves the design of various sages consisting of the pickup transducer, low frequency, audio low power and low noise amplifier, timer, bistable and switches. It also consists of special network components to prevent false triggering and ensure desired performance objectives. A decade counter IC serves the bistable fu ....etc [:=Read Full Message Here=:]
