Electrical Analogue of Digital Logic Gates
Electrical analogue is basically a way of representing the operation of a logic gate such as OR gate, AND gate, NOT gate, etc. in the form of an electric circuit. In other words, we can represent the operation of a logic gate by using basic circuit components like battery, switches, lamps, etc. So, let us discuss the electrical analogue for each logic gate in detail. OR Gate Electrical Circuit The OR Gate is a type of logic circuit in digital electronics which may have two or more inputs but only one output. A two input OR gate is shown in ...
Read MoreDifference between Step-Up and Step-Down Transformer
What is a Transformer? A transformer is an electrical device whose main function is to transmit alternating current between two circuits at a constant value of frequency, but at varying voltage levels. A transformer is constructed by combining two kinds of coil. The first coil carrying the magnetic flux is called the primary coil, while the second coil placed opposite to it, in which electromotive force (E.M.F) is induced is called as the secondary coil. Figure-1 illustrates a standard representation of a transformer. Input voltage at the primary side of the transformer produces the varying magnetic flux on the primary ...
Read MoreDifference between Force and Power
Force and Power are two important concepts in physics. They might appear similar at first sight, but they are completely different from each other. The most fundamental difference between force and power is that Force is a cause that can change or try to change the state of an object from rest to motion or motion to rest, whereas Power is the term used to express the rate of doing work. Read this article to learn how Force is different from Power. What is Force? Force is an external agent that can change the state of an object either from ...
Read MoreDifference Between Radon and Radiation
Radon and radiation are two terms that are often used interchangeably, but they are actually different from each other. Radon is a naturally occurring radioactive gas, while radiation refers to the emission of energy as particles or electromagnetic waves. What is Radon? The gas radon is classified as a noble gas. It may be found at the 86th position of the periodic table. One of the most recognisable radioactive elements is radon. Radon 222 is the longest-lived radon isotope, having a half-life of around 3.8 days. This is a byproduct of the radioactive decay of uranium, thorium, and radium. Radium's ...
Read MoreAddition of Two n-Bit Binary Numbers
In digital electronics and digital systems such as digital computers, calculator, etc., the binary numbers and their arithmetic operations play a vital role. Just like the decimal number system, we can perform all the four basic arithmetic operations, i.e. addition, subtraction, multiplication, and division of binary numbers as well. Read this article to learn how you can add two n-bit binary numbers. What is Binary Addition? Binary addition is a basic arithmetic operation performed on binary numbers in which two binary number of any digit are added to obtain a sum. As we know, a binary number system has base ...
Read MoreThings Needed to start IOT
IOT ie. The Internet of Things refers to all those devices that can communicate over the Internet and can be made accessible or connectable by anybody and from anywhere in the world. IoT is already being used or has been seen implemented in different forms such as in Smart cars and watches, Smart homes, Smart irrigation systems, Smart cities, etc. To start learning IOT, first, it is important to learn about the things that are needed to make circuits. There are some simulators available to make the beginner of IOT learn these concepts without even having the IOT devices available. ...
Read MoreColor Shades using RGB Led
To learn about RGB led and the difference between single-color LEDs, it is important to make a circuit using a microcontroller such as ESP32 or Arduino and RGB led. Then it is important to manage that circuit using a program. There are some simulators available to make the beginner of IOT learn such concepts without even having the IOT devices available. However, to get real results, using the circuit components and making the actual circuit is important. In this article, using two different examples, the way to use the RGB led is given. In example 1, the actual circuit using ...
Read MorePotentiometer and Examples
In this article, using two different examples, the use of potentiometers is demonstrated using ESP32. In the first example, the trimmer type of potentiometer is used to vary the voltage between 0 and 3V. In the second example, the slider potentiometer is used on Wokwi Simulator to show the control of a servo motor. Wokwi simulator is software that can be used for running the code and virtually testing the results without buying the components. The actual diagram of the components is often different from those used in Wokwi, so the actual form of the slider potentiometer is given in ...
Read MoreCreating a Melody Program
A simple buzzer can be connected to the ESP32 controller for producing sound. It can also be used to produce melodies. In this article, using two different examples, the C code is used on Arduino to make the buzzer play the melody. In the first example, “Twinkle Twinkle Little Star”, the poem’s notes are played and in the second example, another famous poem “Jingle Bell” is used for playing the note while making two colored LEDs on and off to create a light show with music. Example 1: Playing the poem notes using buzzer and ESP32 The circuit is made ...
Read MoreDifference Between Bacterial Computing and Computers
The technological revolution has caused computers to literally evolve. It would appear that computers have taken over every aspect of our lives. There have been other non-economic factors in the past that have contributed to the computer's rise to prominence. While the primary function of early computers was calculation, this is now the least essential function of modern computers. Electronic digital computers were first developed for the sole purpose of solving equations. In order to get more done in less time, humans drove the development of computers. As the IT industry is concerned about the rise of mobile devices like ...
