AC DIMMER TO CONTROL AC VOLTAGE, SPEED OF INDUCTION MOTOR OR HEATER COIL
A??voltage controller, also called an??AC voltage controller??or??AC regulator??is an electronic module based on either??thyristors,??TRIACs,??SCRs??or??IGBTs, which converts a fixed voltage, fixed frequency??alternating current??(AC) electrical input supply to obtain variable??voltage??in output delivered to a resistive??load.
Induction motor speed control is done by varying the frequency of the applied voltage. Raising or lowering the voltage can have some speed control effects but these will be small, difficult to control, load-dependent, possibly cause the motor to overheat and, are not generally recommended.

AUTOMATIC IRRIGATION SYSTEM ON SENSING SOIL MOISTURE CONTENT
The project is designed to develop an automatic irrigation system that switches a pump motor on or off upon sensing the moisture content of the soil. In the field of agriculture, use of proper method of irrigation is important. The advantage of using this method is to reduce human intervention and still ensure proper irrigation.

Automatic Load Sharing By Parallel Transformer
Transformer is basically a static device which transfers the electrical power from one circuit to another circuit with desired change in voltage and current at constant frequency. It is only one device which operates at highest efficiency at full load condition. But abnormal condition occurs at overloading condition which may result in severe problem in future.

Automatic Street Light Controal Depend on The Intensity of The Light
In this project we purpose an advanced automatic street light control system that is capable of replacing the old light control system because the manual control of light is not effective in this modern era.

Automatic Train Traffic Gate Control
Automatic Railway Gate Control System is a simple but very useful project, which help is automatically opening and closing the railway gate upon detecting arrival or departure of the train.In general, Railway gates are opened or closed manually by a gate keeper. The information about arrival of train for opening or closing of door is received from nearby station. But some railway crossings are totally unmanned and many railway accidents occur at these unmanned level crossings.

DC MOTOR SPEED CONTROL USING 555 TIMER IC
This project is designed to control the speed of a DC motor using PWM control using 555 IC. The speed of the DC motor is directly proportional to the voltage applied across its terminals. Hence, if the voltage across the motor terminal is varied, then the speed can also be varied.

DeMorgan???s Theorems
A mathematician named DeMorgan developed a pair of important rules regarding group complementation in Boolean algebra. By group complementation, I???m referring to the complement of a group of terms, represented by a long bar over more than one variable.
