Simple Arduino Digital Ohmmeter Circuit
In this post I will show how to construct a simple digital ohmmeter circuit using Arduino and 16×2 LCD display. We will also be exploring the other possible circuit ideas using the same concept. Circuit Objective The motto of this article is not just making an ohm meter to measure the resistance; your multimeter can […]
Arduino based DC Voltmeter Circuit – Construction Details and Testing
In this post, I will show how to construct a DC voltmeter using Arduino where the readings are displayed in 16×2 LCD. The proposed voltmeter design can read up to 30V with tolerance of +/- 0.5 volt. We are going to see how this setup functions and explore other possibilities we can accomplish other than […]
Make this Digital Temperature, Humidity Meter Circuit using Arduino
In our previous article, I have explained how to interface temperature humidity sensor with arduino and read out displayed on serial monitor of arduino IDE. In this post I have explained how to display the reading on a 16×2 LCD display for the proposed digital temperature/humidity meter using Arduino. Introduction This project may be used […]
Testing Alternator Current using Dummy Load
In this post I have explained a method of checking or verifying alternator maximum current delivering capacity using a shunt regulator as the dummy load and an ammeter. The idea was inquired by Mr. Joe. Circuit Question I need help designing an electronic dummy load that can handle high enough power from motorcycle alternator. I […]
Digital Power Meter for Reading Home Wattage Consumption
In this article I have explained a simple digital power meter circuit which can be installed in homes for getting an instant reading of the wattage being consumed by the attached appliances or the loads. The idea was requested by Mr. Nitin. Technical Specifications I m going through a problem. I want to know a […]
