Generally voltage stabilizers are used in this type of applications to maintain constant AC voltage. However due to the abnormal AC supply, relays in voltage stabilizer switches ON and OFF continuously. The frequent energization or de-energization of relays leads to the shortening the life time of appliances and the stabilizer itself. Hence it is better to use this project in order to control the appliances instead of costly stabilizers....

This requires more facilities in transmission and interconnection systems at optimum cost because transmission equipment is much costlier. So the choice between the AC and DC transmission is necessary in order to get the greater reliability. The best choice for the efficient and economical way of power transmission is the HVDC transmission. Let us discuss in brief about HVDC system. What is HVDC? The electric power is produced, transmitted and distributed as an AC power....

What is a Potentiometer? A Potentiometer or simply known as POT, is a three-terminal device with manually adjustable resistance using a movable contact. We all are familiar with Resistors. They are simple electrical devices which resist the flow of current in a circuit. Normal resistors usually have fixed resistance. But what if you want vary the resistance as per the needs of your application? This is where Potentiometers come into play....

Overview Even though the main purpose of ESP8266 WiFi Module is to introduce Internet Connectivity into our small DIY Projects, I believe that we haven’t completely utilized the capabilities of the ESP8266 WiFi Module until now i.e. a true IoT (Internet of Things) Project. I want to take the ESP8266 Projects a step further by actually controlling the ESP8266 over the Internet. In this process, we will learn how to control ESP8266 over Internet by controlling an LED (just to demonstrate the working) connected to one of the GPIO Pins of the ESP8266 WiFi Module over the internet i....
