Clap On / Off Switch Diagram

This is the circuit diagram of Clap On / Off Switch. The circuit allows you to operate your lighting or any circuit device which use 24V / 3A maximum supply, simply by clapping your hands.It has a relay output that can be used to turn external devices on/off. This circuit Read more…


Traffic Baton circuit with LED Flasher

This is the traffic baton circuit which available in two versions that are traffic baton with LED flasher and traffic baton with bulb flasher. Both the circuits powered with a 6V, 4.5Ah rechargeable battery, which is clipped to the operator”s waistband. This circuit which come from EFY mag, will help Read more…


Electronic candle circuit electronic

This is a simple and easy built electronic candle circuit which build using TTL (transistor-transistor logic) that are 74LS164, 74LS86 and 74LS00. This circuit will give the effect of candle light in a normal 220V electric bulb lamp. A candle light, as we all know, resembles a randomlyglimmering light. So, Read more…


light fence circuit electronic

This is the light fence schematic diagram uses LDR as the light sensing. The fundamental issue with the greater part of standard light sensors is that they require exact arrangement of light bar to quiet the circuit throughout standby mode. The circuit portrayed here is sensitive to the point that Read more…


simple trafic light controller circuit

Here the simple traffic light controller which is could be used to educate kids rudiments of traffic light guidelines. The circuit utilizes easily available electronic parts. It generally consists of rectifier diodes (1N4001), a 5V regulator 7805, two timers circuit using IC 555, two relays (5V, single-changeover), three 15W, 230V Read more…


Door Bell with Flashing LEDs

This is the door bell circuit with flashing LEDs to make the circuit more attractive. IC1 (NE555) is applied right here as being a clock generator. It is actually set up as an astable multivibrator whose frequency could be altered using the support of potensiometer VR1. The clock pulses received Read more…


Portable 230V lamp flasher circuit electronic

This is a portable, 230V high-power incandescent electric lamp flasher circuit diagram. It is actually basically a double flasher (alternating blinker) which could manage two different 230V AC loads (bulb lamps L1 and L2). The circuit is completely transistorised and battery-powered. The free-running oscillator circuit is realised working with two Read more…
