Hello friends, I hope you all are doing great. In today's tutorial, I am going to do an Arduino 74HC165 Interfacing and we will have a look at How to increase Input Pins of Arduino. 74HC165 is a shift register and works on the principal of Parallel In Serial Out. In my previous tutorial Arduino 74HC595 Interfacing: Increase Output Pins, we have seen How to increase the output pins of Arduino and today we are gonna do exact the opposite and we will increase the input pins.
74HC165 will take 8 parallel inputs from different sensors or buttons etc and will send them to serial OUT Pin, which will be connected to Arduino. So, if you are working on a project where you want to get data of 15 or 20 digital sensors then you can use this shift register and ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you How to Interface Arduino with 74HC595 & 74HC165. I have already interfaced these shift registers separately with Arduino. In the first tutorial we have seen Arduino 74HC595 Interfacing in which I have discussed How to increase the output pins of Arduino using 74HC595. After that in second tutorial we have seen Arduino 74HC165 Interfacing where we have increased the input pins of Arduino.
So, now we are gonna interface both of these shift registers with Arduino UNO and will increase both input and output pins of Arduino. I have also given the Proteus simulations for download at the end of this tutorial along with Arduino code. So, lets get started with In ...
Hello friends, Hope you are doing fine and having a good time in your life. The topic that I am going to discuss today is a very interesting and important one in the context of blockchain. I will discuss smart contracts in this article and I am sure you will learn the concept by the end of this tutorial. I have mentioned smart contracts in my previous articles and defined them before.
Before discussing smart contracts, let’s first revise what a contract is, and then we will talk about smart contracts.
Contract
When two persons or two parties want to carry out a deal or a transaction such as buying property, they need some proof for future reference.
So, a contract between two or more individuals is a legal document that serves as proof for t ...
There have been numerous incidences of teenagers killing themselves with a gunshot, a shooter perpetrating mass violence, or a family member accidentally shooting another. These cases have occasionally brought about discussions about “smart gun” technology.
The discussion of smart gun technology started in 1995 in the NIJ (National Institute of Justice), where a technological approach was recommended to reduce the number of incidents where police officers were killed by assailants who grabbed guns. In the recent years, we have also seen leaders like Barack Obama recommending the commercialization of tech-gun safety systems.
What is smart gun safety?
The phrase smart gun is adopted by the society at large as a form of a personalized electronic safe ...
Hello Friends! I hope you are enjoying your life and having fun. Today, I am going to give you brief details on the Introduction to 6n137. It is a photocoupler that is used to transfer electrical signal with the help of light between two separated circuits. It consists of one chip photo IC and high emitting diode. It is a 8 pin device which comes in DIP package. I'll try to cover as many aspects as possible related to this photocoupler. Let's get started.
Introduction to 6n137
6n137 is a photocoupler also known as optocoupler that is used to connects the two electrically isolated circuits with the help of light.
It consists of 8 pins where inputs and outputs terminals are electrically isolated which help in controlling the large power, curren ...
Hello friends, hope you all are fine and having fun with your lives. Today, I am going to share a tutorial on DC Motor Speed Control using Arduino in Proteus ISIS. In my previous post, we have seen How to design a DC Motor Direction Control Project using Arduino in Proteus ISIS and if you haven't checked it out then I would recommend you to have a look at it first. Because, in today's tutorial, I am gonna extend that tutorial and will add the DC Motor Speed Control in it. So, today, we will control both the direction as well as speed of the DC Motor. Moreover, you should also have a look at How to use Arduino PWM Pins if you are not much familiar with PWM control.
In the previous tutorial, we have seen How to control the direction of a DC Motor, w ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give a detailed discussion on Introduction to LM4040. LM-4040 is specially designed for an accurate micro-power shunt voltage reference. These voltage references includes the standards of 2.5V, 3V % 5V respectively. LM-4040 has three different grade A, B and C grades and they have o.1%, o.5% and 1% tolerances respectively.
This device is available in different packages and each package has different individual dimension which will be explained later. We can achieve an excellent performance from this device when it is operating at the current ranging from 60uA to 15mA and its temperature coefficient is 20 ppm per degree. In order to maintain good stability ...
Momentum is a key idea in physics. It’s super important for understanding how things move. It’s a vector quantity, meaning it has direction and magnitude. So, we define it as the mass of an object multiplied by its velocity. Mathematically, momentum (p) can be shown like this:
p=mv
In this formula, (m) stands for mass and (v) for velocity. This simple equation shows us how the mass of an object affects its momentum by showing how fast it’s going.
Historical Background:
The idea of momentum goes way back to the beginnings of classical mechanics, thanks to some great scientists like Sir Isaac Newton & René Descartes. Newton gave us the laws of motion, which helped us understand how momentum stays the same in closed systems. Descartes' thoughts about the conservation of “quantity of mot ...
Hi Everyone! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to CA3130.The CA3130 is a BiMOS Operational Amplifier that comes with MOSFET at the output. The term BiMOS suggests that it projects the advantage of both Bipolar and CMOS op-amp technology.
This IC comes with high bandwidth due to bipolar op-amps and consumes less current due to CMOS op-amp, making it a perfect fit for mobile jammers and voltage follower circuits.
I suggest you read this post all the way through as I’ll detail the complete Introduction to CA3130 covering datasheet, pinout, features, and applications. Let’s get started.
Introduction to CA3130
The CA3130 is a BiMOS Operational Amplifier that contains MOSFET at the output. This chip consumes les ...
Mathematics and its branches make a group of disciplines that appear the most challenging for students. While you could have an innate talent for sciences and good memory, this can’t be the only thing to rely on in learning maths.
It also requires consistency and tireless work. What makes math studies even more difficult is that students often have to master many disciplines at the same time – algebra, geometry, mathematical analysis, statistics, etc. Not counting other vital college subjects.
With such great pressure, it seems impossible to succeed in every single subject. In fact, it would be impossible but for the technologies, we have nowadays. Thanks to the wide popularity of academic help services and their availability, students can receive ...
