This circuit protects refrigerators as well as other electrical appliances from over and under voltage. By the name itself we can say that if the input voltage is more or less than the required voltage then the electrical appliance is turned off nothing but it gets disconnected from its respective power supply.
This circuit uses an operational amplifier IC LM324 which is used as a comparator. Generally, the IC LM324 consists of four operational amplifiers, of which only two operational amplifiers are used. In this IC, we ha ....etc

Introduction
Earlier, we are looking into the face of future when we talked about automated devices, which could do anything on instigation of a controller, but today it has become a reality.
An automated device can replace good amount of human working force, moreover humans are more prone to errors and in intensive conditions the probability of error increases. Whereas an automated device can work with diligence, versatility and with almost zero error.
This is why this project looks into co ....etc

Mobile Controlled Electrical Appliances
Project Introduction:-
This project talks about the basic definitions needed to understand the project better and further defines the technical criteria to be implemented as a part of this project. This project is a teleremote circuit that enables switching ‘ON’ and ‘OFF’ of appliances through telephone lines. It can be used to switch appliances from any distance, overcoming the limited range of infrared and radio remote controls. The circuit described in the project c ....etc

Controll Electrical Home Appliances with your TV Remore.
Just about every piece of domestic hi-fi or video unit comes with a remote control handset these days. Infrared (IR) remote controls are everywhere. Just about every piece of electronic equipment you can think of has one “ TVs, VCRs, DVDs, hi-fi systems. Even the lastest cameras have them!

Why are they so popular? The answer is simple convenience. You can change TV channels without leaving your chair. Or adjust the volume on your stereo system. Or, in the case ....etc
