In this post I will be talking about the Chinese M4430 digital ammeter, voltmeter module which is a really neat, compact digital meter that you can mount on a panel. Whats great about it is that it is designed to measure and show us both the DC voltage and the current at the same time. […]

AC Ammeter Circuit for Measuring Current across 220 V Appliances
In this article I have explained how to build a simple AC ammeter circuit which can be used for checking the current consumption of household 220 V or 120 V appliances. The main reason for high monthly utility bills is the use of large electrical equipment like refrigerators, washers and dryers, dishwashers, etc. These appliances […]
Make this Advanced Digital Ammeter using Arduino
In this post I will show how to construct a digital ammeter using 16 x 2 LCD display and Arduino. We will understand the methodology of measuring current using a shunt resistor and implement a design based on Arduino. The proposed digital ammeter can measure current ranging from 0 to 2 Ampere (absolute maximum) with […]
How to Make a Digital Voltmeter, Ammeter Module Circuits
In this article I have explained how to build a digital voltmeter and a digital ammeter combined circuit module for measuring DC volts and current through different ranges, digitally. Introduction Electrical parameters like voltage and current are inherently associated with electronics and with electronic engineers. Any electronic circuit would be just incomplete without appropriate supply […]
