Mostly used to regulate the current flow by adding/subtracting resistance from the circuit, these resistors are available in many shapes and sizes. These resistors can be broadly classified as
Varistor – Symbol, Working, Types and Applications The small package of resistance, the resistor is used in so many circuits, in so many forms, that it is almost an omnipresent electric component. From the very basic fixed resistors, where the resistance remains unchanged, to different types of variable resistors, whose resistances change according to different
Ballast Resistor – Working, Types, Applications & Uses According to the English dictionary, “ballast†means something that gives stability. Thus when referring to an electrical ballast, we mean an electrical device that plays an important role in maintaining the stability of the electrical circuit. However, the question you may have is how does it provide
Digital Potentiomter – Working, Internal Structure & Applications One of the most common types of variable resistors is the potentiometer. Potentiometer or “potsâ€, are three terminal devices, used to vary the resistance in a circuit. We have dealt in depth about this topic, in our article “potentiometersâ€, if you want to learn about the basics
Rheostat – Working One of the most omnipresent electric components is the resistor. In applications where variable resistance is required, potentiometers and rheostat are mostly preferred. We have already discussed potentiometers in our previous article about the same. Here we shall discuss about rheostat in detail. What is a Rheostat? Rheostat is a type of
Ultrasonic Blind Walking Stick According to the WHO, about 30 million people are estimated to be permanently blind worldwide. These people are totally dependent on others. They even cannot walk on their own. We have created designed and built an “Ultrasonic Blind Walking Stick†device which will help blind people to walk with ease independently.

Password Based Keypad Door Lock  In this article, a digitally secured lock based on password verification is explained. The system uses a seven segment display array to show the password, a matrix keypad to enter the numbers/password and operates a relay (to activate the solenoid valve) for locking and unlocking purpose. The system alarms through
UART Between Microcontrollers Using Proteus UART stands for Universal Asynchronous Reception and Transmission of data serially between two terminals. This mode of communication has the advantage of data transmission using lesser number of I/O Pins. For longer transmission distances this is essential as it involves less number of transmission wires. In this article, we shall
