Different Types of Transformers: Step-Up, Step-Down & More It is important to know the different types of transformers for electrical engineering applications and to design power systems. Transformers are electromagnetic devices based on the principles of electromagnetic induction discovered by Michael Faraday, and they perform very important functions for power generation, transmission, distribution, and electronic circuits. This large reference… |

Calibration of Ammeter, Voltmeter, and Wattmeter using Potentiometer We know that voltage, current, and power are measured in volts, amps and, watts and voltmeter, ammeter, and wattmeter are used to measure these parameters. Though these measuring instruments are manufactured with the care they may still give error readings at the customer end. So these instruments are calibrated to minimize the error. Here in this article, we will explain… |

LED VU Meter using LM3914 and LM358 We can consider the Volume Meter as an Equalizer, which is present in the Music systems. In which we can see the dancing of lights (LEDs) according to the music, if the music is loud, equalizer reaches to its peak and in low music it remains Low. We have also built a Volume Meter or VU meter, with the help of MIC, OP-AMP and LM3914, which glows the LEDs as per strength of… |

Simple Arduino Digital Voltmeter With a simple knowledge of Arduino and Voltage Divider Circuit, we can turn the Arduino into Digital Voltmeter and can measure the input voltage using Arduino and a 16x2 LCD display. Arduino has several analog input pins that connect to an Analog-to-Digital converter (ADC) inside the Arduino. The Arduino ADC is a ten-bit converter, means that the… |

Simple Digital Voltmeter Circuit with PCB using ICL7107 In this project we are going to build a Digital Voltmeter without using any microcontroller. Here we are using a very popular IC for voltage measurement namely ICL7107/CS7107. Using ICL7107, we can build accurate and very low cost voltmeter. ICL7107 is a 3.5 digit analog to digital converter (ADC) which consumes very low power. The IC has internal circuit for driving… |

0-25V Digital Voltmeter using AVR Microcontroller In this project we are going to design a 25V range digital voltmeter by using ATMEGA32A microcontroller. In ATMEGA, we are going to use 10bit ADC (Analog to Digital Converter) to build a digital voltmeter. Now the ADC in ATMEGA can not take a input more than +5V, so for getting a higher range we are going to use a voltage divider circuit. … |
