The articles explains a digital thermometer circuit project that works without a battery. Instead of a battery the circuit utilizes a small solar cell and operates by deriving power from the ambient light available from the surrounding light sources. This allows the circuit to be extremely compact, light weight, versatile and hassle free while measuring […]

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, […]
Digital-to-Analog (DAC), Analog-to-Digital (ADC) Converter Circuits Explained
A digital-to-analog converter (DAC, D/A, D2A, or D-to-A) is a circuit designed to convert a digital input signal into an analog output signal. The analog-to-digital converter (ADC) works in the opposite way and transforms an analog input signal into a digital output. In this article I will comprehensively discuss how digital to analog, and analog to digital converter circuits work, using diagrams and formulas. In […]
12 Basic Digital Logic Circuits Explored
In the following paragraphs I will try to explain the most basic foundations of digital electronic circuits: namely logic gates and logic flip-flops. Whether it is a complex and larger digital circuits, or as simple as a BCD counter, for example the 7490, or a large-scale integration (LSI) microprocessor chip, eventually all of these comprise […]
