220V Lamp Touch Dimmer circuit electronic

Here the 220V AC lamp touch dimmer circuit. By only touching this touch dimmer you are able to increase the light intensity of incandescent lamps in three stages. The touch dimmer is designed all around 8-pin CMOS IC TT8486A/TT6061A especially produced for touch dimmer applications.


200W Lamp Flasher Circuit Electronic

This is the 200W lamp flasher circuit diagram. The frequency/speed of the lamp flashing can be adjust with the range of 1Hz to 5Hz. You can use the PR1 variable resistor (trimpot) to adjust the flashing speed. The duty cycle of lamp flashing can be adjusted using PR2 variable resistor.


Automatic Switching-on Emergency Light Circuit

Automatic Switching-on Emergency Light The schematic diagram shown right here is the automatic switching-on emergency light circuit which is controlled using IC. The most important capabilities of this circuit are: automatic switching-on of the light on main power failure and battery charger with overcharge protection. When mains electrical power is Read more…


automatic light controller circuit

This is the circuit diagram of automatic light controller which use 78xx voltage regulator IC series. The voltage regulator ICs deliver a constant output voltage, as against a extensively fluctuating input supply, when the common terminal is grounded. Any voltage about zero volt (ground) interconnected within the common terminal is Read more…


sound activated light diagram

This is the schematic diagram of sound activated light or lamp. The lamp or light will be turned on while a loudy sound catch by the microphone (for example: hand clap) How this sound activated light works: The condenser microphone fitted inside a position to catch the sound and generates Read more…


120V or 240V Powered LEDs Circuit

You can easily activate the LED from home electrical power line with this circuit diagram. You just need to add a nonpolar capacitor and a 1Kohm / 1W metal oxide resistor to activate the LEDs from home power line with serial connection.
