Power factor measurement

Power factor measurement using Atmel AVR Micro-Controllers

To learn about the power factor measurement, you should have a basic knowledge of power factor. There are three types of loads. Resistive  Inductive Capacitive When we apply AC voltage to resistive loads it will not change the current wave form. But inductive loads will force to lag the current waveform and in the case …

Pololu Wixel Shield

Pololu Wixel Shield for Arduino User’s Guide

1. Overview The Wixel shield seamlessly enables a wireless link (with a typical range of ~50 feet) to replace your Arduino’s USB interface, which means you can use the standard Arduino computer software to: wirelessly program the Arduino (this feature is not available with the Arduino Leonardo or the A-Star 32U4 Prime). wirelessly debug sketches with the Arduino serial monitor. wirelessly communicate with …

Wireless Communication of Multiple Variables

Wireless Communication of Multiple Variables Between 2 Arduinos Using HC-12

In this tutorial, I will show you how to achieve wireless communication of variables between 2 Arduinos using the HC-12 module, that operates from 433,4-473 Mhz. HC-12s are wireless modules for arduino to arduino communication, because they can send multiple variables over long distances-ones up to 1km-using only 2 digital pins, not even PWM pins, …
