Arduino based DC Voltmeter Circuit – Construction Details and Testing

In this post, we are going to construct a DC voltmeter using Arduino where the readings are displayed in 16×2 LCD. By: Girish Radhakrishanan    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 … Read moreArduino based DC Voltmeter Circuit – Construction Details and Testing

Make this Digital Temperature, Humidity Meter Circuit using Arduino

In our previous article, we learned how to interface temperature humidity sensor with arduino and read out displayed on serial monitor of arduino IDE. In this post we are going to learn 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 … Read moreMake this Digital Temperature, Humidity Meter Circuit using Arduino

Testing Alternator Current using Dummy Load

The post explains 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 need to know … Read moreTesting Alternator Current using Dummy Load

2 Frequency to Voltage Converter Circuits

As the name suggests frequency to voltage converters are devices that convert a frequency input data into correspondingly rising or falling voltage levels, in response to the increasing or decreasing frequency levels. Here we study two advanced designs using IC VFC32 and IC LM2907 The previous post explained a simple single chip voltage to frequency … Read more2 Frequency to Voltage Converter Circuits
