Automatic Railway Gate Control System Using Arduino & IR Sensor About a million people have died over the past 5 years in unmanned railway crossings all over the world. At least 1/3rd of the railway crossings are unmanned due to their remote placement and less traffic. The Automatic Railway Gate Control System using IR Sensor
Variable Resistor – Working, Construction, Types & Applications One of the critical pieces in an electric circuit, the resistor is the most omnipresent electronic component. Available in wide varieties, these resistors can be used in various applications. Â Resistors are broadly classified as fixed and variable resistors, according to the type of resistance value they offer.
Potentiometer – Working, Circuit Diagram, Construction & Types Resistor, a small bundle of resistance, is one of the most used basic components in an electric circuit. 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.
Marantz SR-6011 Receiver Marantz is one brand that is known for making some of the most feature rich and premium class AV receivers and they are eyed by people seeking entertainment minus compromise. If you are looking for a top notch performer in this segment, the SR6011 from Marantz is worth a consideration. This versatile
Interfacing GSM Module Using Proteus The Proteus simulation software can be used to interface real-time modules like the GSM Module.

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
Arduino Solar Tracker Solar energy is one of the fastest growing industries in the world; today more than 65 GW energy is produced by solar power. Since solar energy is renewable, it is a good power source, especially for developing countries. In this project, I am going to show you how to make a solar
