Introduction
When the subject is ESP8266, it is normal that our attention is on the Wifi module. We've already discussed some applications in previous articles, and there's still a lot of cool stuff to see in the future. We've looked at how the ESP8266 communicates with the world via wifi, and now we'll look at how it does it through its pins.
We will make a decision here. The ESP8266 is found in several modules. Each module with its pin provision. ESP-12 modules provide the most features. To make better use of these features and have a more protoboard-friendly module at hand, we will analyze the NodeMCU module with the ESP-12E.
Overview and Electrical Data
The NodeMCU pins are available in two rows with a spacing that allows them to fit on a breadboard (in particular, I find the pins a ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you What are the main features of embedded operating systems? In order to operate, most of our digital home appliances, industrial machines, vehicles, and all other sorts of machines require embedded Operating Systems that run all software that controls functionality. The reason why unitary control of the processes is necessary, among others includes efficiency. Instead of managing every embedded system separately, an embedded OS controls all programmable and fixed hardware functions. Even though they are widely in use, the full spectrum of features that these types of software have to offer is not familiar to a broader array of the public. That is why, in this a ...
Hey everyone! Hope you all are doing great. Today, I am going to give you the details on the Introduction to 2n4391. It is a simple N type JFET (Junction field effect transistor) which consists of three terminals called drain, source and gate and are denoted by D, S and G receptively. It is mostly used in analog switches and current limiters. I am going to give you a brief details on this transistor. Let's get started.
Introduction to 2n4391
2n4391 is a field effect transistor that consists of three terminals known as drain, source and gate.
It is called field effect transistors because static field performs as important part in the operation of this transistor.
Unlike normal transistors, it is a voltage controlled device as it doesn't requ ...
To understand this section, we must know a little history. The history of the development of printed circuits is not as old as that of the industrial revolution, around 1950 is when the first PCBs began to be commercialized, however, in the early 1900s it was when the first attempts at PCB designs emerged.
The human being had the need to have electrical equipment that had a reduced size, before this the search began to replace the complex and extensive cable connections with electronic components.
It was on March 2, 1925, that Charles Ducas first filed a patent that included creating an electrical path directly on an insulating surface.
Technology has advanced and electronics are not left behind, as can be seen in the previous image, the first pr ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to Namespaces in C#. Namespaces are considered as libraries in C#. If you have worked on any other programming language then you must be aware of the term library which contains all classes & methods etc. In C#, this functionality is performed by namespaces.
In 12th tutorial, we have seen Introduction to Methods and in 13th part, we have seen Classes in C#. Methods are simple storage units and stores code only, Classes are slightly bigger storage units and can store methods. Now Namespaces are giant storage units, which can save anything in them i.e. classes, methods, namespaces etc. So, let's have a look at them in detail:
Int ...
Hi readers! I hope you are doing well and learning new things daily. Today, we have a detailed overview of the MAP(Manifold Absolute Pressure) Sensor, its working principle, types, structure, and features. The Manifold Absolute Pressure (MAP) sensor is a crucial element in a vehicle's engine to control pressure. The MAP sensor measures the pressure inside the intake manifold and transmits this data to the ECU so that fuel injection, ignition timing, and air-fuel mixture can be optimized. The MAP sensor is used to ensure engine efficiency, performance, and fuel economy.
The MAP sensor functions by the transformation of manifold pressure variations into an electrical signal, which is then interpreted by the ECU to calculate engine load. It is complemented by other sensors, including the M ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a detailed Introduction to Structures in C#. It's our 17th tutorial in C# series. Structures are quite similar to classes but have few differences as well, which we will discuss today.
We have discussed C# Classes in 13th lecture, so you must read it once as we will use that knowledge in today's lecture as well. So, let's get started with Introduction to Structures in C#:
Introduction to Structures in C#
Structure in C# is a value type data type, created by using keyword struct, and can have fields, methods, properties, operators etc. just as in C# Classes.
Main difference between C# Class & Structure is that C# Class is a Reference Type Date type while C# St ...
Hi Guys! Hope you doing well. Today, I am going to discuss 5 Ways to Keep Your Data Safe and Secure. Data security is one of the biggest issues of today’s businesses with data breaches being more common than ever. Companies take several steps to secure data, but nothing seems to be working with hackers improving their tactics to attack businesses.
If you are also running a business then you need to be careful about the data as it is not just yours but your customers’ data too that is at risk.
A business faces several risks in regards to data. These include the risk of theft and the risk of loss.
Data theft can occur in several ways. While hacking is a common issue, sometimes employees can leak data as well. On the other hand, data theft can be ...
Probability theory is a math area that tells us how likely things are to happen. It helps us understand and measure chances when we're not sure about what will happen next. This is useful for making daily decisions and solving problems in fields like business, engineering, and health.
It also helps people working with data, like in statistics or data science, to make smart decisions based on the information they have. In short, learning about probability helps us deal with uncertainty and make better choices in life.
Understanding Probability Basics
Understanding probability is like guessing how likely something is to happen. It's about figuring out all the possible outcomes of something and what might actually happen. Like if you're rolling a dice, the sample space is all the numbers ...
Hi Guys! Hope you’re well today. I welcome you on board. Thank you for clicking this read. In this post today, I’ll discuss how to calculate PCB trace width?
The PCB (printed circuit board) is a mechanical layout that electrically connects different components on the board using conductive copper traces that maintained current throughout the circuit board. Different electrical components are placed on the non-conductive substrate which are soldered from the other side of the board. On the non-conductive side of the board copper traces electrically connect these components.
Earlier end-to-end wiring was used in place of PCB boards but now it’s become obsolete. Needless to say, PCB has revolutionized the modern electronics that are precise and com ...
