Schematic Diagrams

This project can be used to control up to four industrial electrical appliances with the help of a joystick and an Arduino Nano board. The block diagram of the joystick-controlled industrial automation system is shown in Fig. 1. The circuit diagram of the joystick-controlled industrial automation system is shown in …

This project presents a user-friendly way of controlling four electrical equipment using an LCD-based interactive menu. Usually, each equipment is controlled by a pushbutton switch. In this design, instead of four pushbuttons, only two pushbuttons are used to control the operations of four electrical equipment. Pushbuttons provide a hardware interrupt …

In this article, our focus is related to air pressure while filling air in the tyre. This is important because the tyre may get burst and create many other problems due to excessive air pressure inside. So, we have proposed one method in which, one can detect the pressure of …

Table of Contents What is a Tunnel Diode? A Tunnel Diode is a heavily doped p-n junction diode. The tunnel diode shows negative resistance. When voltage value increases, current flow decreases. Tunnel diode works based on Tunnel Effect. The following image shows the symbol of a Tunnel Diode. Leo Esaki …

LM317T and LM337T ICs are well-known, low-cost adjustable voltage regulators capable of delivering up to 1.5A current output with power dissipation of up to 20W. LM317T produces a positive output voltage, while LM337T produces a negative output voltage. It is useful to have a bipolar power supply with LM317T and …

Capacitors and inductors are important electrical components used in electronic circuits, as they offer a host of benefits including a long life and high reliability of the circuits they are used in. Electric circuits are an integral part of any electronic device. Their main task is to direct and control …

Table of Contents What is a Photodiode? It is a form of light-weight sensor that converts light energy into electrical voltage or current. Photodiode is a type of semi conducting device with PN junction. Between the p (positive) and n (negative) layers, an intrinsic layer is present. The photo diode …

Solar streetlights can be easily integrated with a dusk-dawn controller by simply employing a pnp transistor and a few resistors where the solar panel itself works as the sensor. But what about other lighting sources that do not employ solar panels such as automatic lighting systems in small wind turbines, …

The new process involves less cumbersome steps and works on surfaces such as skin or paper Processing methods for printed electronics these days involves steps such as chemical bath to rinse away unwanted material, a hardening process to ensure layers don’t mix, or an extended bake to remove traces of …

You have received an important phone call on your mobile and you have found that its battery is about to drain. Either you need take out power banks (if you have carried along with you) or need to search for charging points. You think that just a few hours back …
