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 […]

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 […]
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 […]
Simple Digital Stopwatch Circuit (4-Digit)
In this article we’ll study a digital stopwatch design configured around the very popular IC LM555 in conjunction with a 4-digit counter IC with multiplexed 7-segment output drivers (MM74C926). Written and Submitted by: Jennifer Goldy Circuit Operation IC MM74C926 is internally made up of a 4-digit counter, an output latch up stage, a npn output […]
5 Simple Electronic Dice Circuits Explained [Digital Dice]
We all know what a dice is and how manually a dice is shuffled and thrown to get a random number. In older times when we did not have computer games or mobile games, we used to play with various indoor games that required tossing a cubical thing called dice having 1 to 6 dots […]
Digital Buffer – Working, Definition, Truth Table, Double Inversion, Fan-out
A buffer stage basically a reinforced intermediate stage which allows the input current to reach the output without getting affected by the output loading. In this post I will try to explain what digital buffers are, and we will be taking a look at its definition, symbol, truth table, double inversion using logic “NOT” gate, […]
