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… |

Arduino Based Digital Ammeter Ammeter is used to measure current flow through any load or device. Here in this Arduino Ammeter, we will explain about measuring of current by using ohm’s law. It will be quite interesting as well as a good application of basic science that we studied in our school days. All of us are well known of ohm’s law, It states that “the potential… |

Digital Ammeter Circuit using PIC Microcontroller and ACS712 Measuring the voltage and current will always be helpful while making or debugging any electrical system. In this project we are going to make our own Digital Ammeter using PIC16F877A Microcontroller and current sensor ACS712-5A. This project can measure both AC and DC current with a range of 0-30A with an accuracy of 0.3A. With few modifications on the code you can also use… |

100mA Ammeter using AVR Microcontroller In this project we are going to make a low range ammeter using ATMEGA8 microcontroller. In ATMEGA8, we are going use 10bit ADC (Analog to Digital Conversion) feature to do this. Although we have few other ways to get the current parameter from a circuit, we are going to use resistive drop method, because it’s the easiest and simplest way to get current parameter. … |
