How to Use Relays to Control High-Voltage Circuits with an Arduino

How to Use Relays to Control High-Voltage Circuits with an Arduino

To control high-voltage or high-power circuits with an Arduino, you have to isolate them from the Arduino with a relay. Here's how!


Opposites Attract: A Review of Basic Magnetic Theories

Opposites Attract: A Review of Basic Magnetic Theories

Electric machineries are based on the basic principles of electromechanical conversion, which use either the electrostatic or the electromagnetic principle. This technical article deals with the magnetic circuit theory for the conversion of one form of energy to another.


How to Use an Arduino as a Web Server

How to Use an Arduino as a Web Server

By equipping an Arduino with an Ethernet shield you can turn it into a simple web server, and by accessing that server with a browser running on any computer connected to the same network as the Arduino, you can perform a variety of tasks.

How to Use the Arduino’s Digital I/O

How to Use the Arduino’s Digital I/O

The digital inputs and outputs (digital I/O) on the Arduino are what allow you to connect sensors, actuators, and other ICs to the Arduino . Learning how to use the inputs and outputs will allow you to use the Arduino to do some really useful things, such as reading switch inputs, lighting indicators, and controlling relay outputs.

Use an Arduino to Control a Motor

Use an Arduino to Control a Motor

Controlling a motor with an Arduino is relatively easy. In addition to simply spinning the motor, you can control the position of the motor shaft if the motor has a rotary encoder.

AC-Equivalent Circuit Modelling

AC-Equivalent Circuit Modelling

The basic converters complete equivalent circuits can be studied here which include the basic AC modeling approach and the results for several converters. A simple circuit diagram is used for high-frequency converters. We will construct the non-linear model and convert it into a linear circuit that describes the small-signal performance of a circuit.
