Welcome to today's article on our comprehensive Raspberry Pi 4 programming guide. As we saw in the previous article, the Raspberry Pi 4 may power a single seven-segment display. In addition, we also interfaced a Raspberry Pi with 4 Seven-Segment Display Modules to display the time. However, this guide will show you how to construct a Raspberry Pi 4 crypto miner that uses very little electricity.
Cryptocurrencies have been the subject of widespread conversation for some time now. It's possible to use your computer to create them, and they can be used as currency. Because of this, the Raspberry Pi can also be used for Bitcoin mining. It's also possible to mine other cryptocurrencies. One drawback of mining is that the cost of electricity often excee ...
Hello friends, I hope you all are fine. In today's tutorial, we are going to have a look at What Are Cyber Threats And How Can You Stay Protected? If you have any questions/queries, please ask in the comments.
Cybersecurity is a rising concern for many people and businesses in this techno-savvy 21st-century world. However, not many people realize cyber threats don't discriminate and believe that it's for fortune five companies and wealthy personalities. To demystify the ideas regarding cyber threats, it's important to define what they're, identify them, and explore some ways to protect themselves.
What Is A Cyber Threat?
The word cyber originally referred to cybernetics. This is the science of how machines and animals work. Later on, cyber came t ...
Hi Guys! Hope you’re well today. I welcome you on board. Happy to see you around. In this post today, I’ll detail the Introduction to Arduino Sensor Shield.
Arduino Sensor Shield is a board compatible with the Arduino Boards and comes with the standard header layout. It is used to connect sensors, servos, LCD with the Arduino board without soldering. This board is connected with the Arduino Board using the jumper wires.
I suggest you read this post all the way through as I’ll be discussing the complete Introduction to Arduino Sensor Shield.
Let’s get started.

Hello Guys! Hope you’re well today. I welcome you on board. Thank you for clicking this read. In this post today, I’ll walk you through the Introduction to AMS1117.
The AMS1117 is a common voltage regulator that comes with both fixed and customizable voltages. It is a 3-pin device mainly used to drive load under 1A. The output voltage ranges from 1.5V to 5V. When it works at maximum current, it results in a low dropout voltage of 1.3A.
I suggest you read this post all the way through, as I’ll be discussing Pinout, datasheet, features, and applications of this tiny device AMS1117.
Let’s jump right in.

The AMS1117 is a common voltage regulator mainly used for high-efficiency linear regulation and post-regulation switchi ...
Update: Few bugs were reported by some readers, which I have corrected and updated the code. Now, its fully tested and 100% working.
Hello friends, hope you all are enjoying the start of winter season. By the way, I really hate winter season and I just want to hibernate in this season . :) Well coming to our today's lecture, my today tutorial, serial port in VB 2010, is actually based on a request made by one of the member on my Facebook Page and as it is a really good topic so i thought to share it.
Today we will make a software on Microsoft Visual Basic 2010 in which we will send data through the serial port in VB 2010. In this software we will send the data and also receive it. Simply follow all the given steps carefully and you can easi ...
Hi Guys! I hope you’re doing great. Today, I am going to share Chapter Zero of the ESP32 Programming Course. I have called it Chapter 0 because today, we won't practically work on the ESP32. Instead, I’ll walk you through the detailed theoretical Introduction to the ESP32 Module, where we will discuss the ESP32 Pinout, Datasheet, Specifications, Features, Applications etc. in detail.
ESP32 is an embedded module that supports both WiFi and BT(dual-mode) connectivity and is thus used in Cloud-based IoT projects. ESP32 is the upgraded model of the ESP8266 module and is designed by Espressif Systems in China.
The following tables show the main features and technical specifications of the ESP32 module.

If you plan to run a start-up, it helps to have some basic understanding of IT management. Here are some key pointers on how best to manage your business IT systems:
You should know how your IT systems work and how they can be managed. This will help you keep them working well, which is especially important if your business depends on them for important functions like payroll or customer service. The earlier in the process that someone understands their role and responsibilities in running the company's technology, the better off they'll be when troubleshooting problems arise later on down the road.
How to Manage IT Management for Start-Ups
Make sure your hardware and software are secure.
Ensure that you have the right licenses for your ...
Hello, everyone, I hope you are doing great. In this tutorial, I am going to explain you about C# checkbox control, in my previous tutorials I have already explain you, C# RadioButton Control, C# ListBox Control, C# Button Control and C# Checked ListBox Control. C Sharp checkboxes have their own values in point of sale mission and desktop application development. Checkboxes are basically used to retrieve the specific data from the user.
C# CheckBox allows the user to give specific input. It's mostly used where we have to retrieve the specific data from the user such as the gender selection, terms and condition agreement, and age-restricted data. You can simply use a single object C# CheckBox or multiple objects it totally depends on your requireme ...
Hello readers, I hope you are all doing great. Welcome to the 2nd lecture of Section 5(ESP32 Sensors) in the ESP32 Programming Series. In the previous tutorial, we discussed the built-in ESP32 Hall Effect Sensor. In this tutorial, we will discuss another inbuilt sensor of the ESP32 i.e. Capacitive Touch Sensor.
ESP32 Board has 10 built-in capacitive touch pins, which generate an electrical signal when someone touches these pins. These ESP32 touch pins are normally used to wake up the board from deep sleep mode. These touch pins are also used to replace the normal mechanical buttons with touch pads, improving the presentation of the IoT projects.
Here's the video demonstration of the ESP32 Capacitive Touch Sensor:
Before going forward, let's first understand how this touch sens ...
Hey Fellas! I hope you are doing great and having fun. We love when you keep coming back again and again for what we have to offer that resonates with your needs and requirements. I am back to give you a daily dose of useful information so you can excel and grow in your relevant field without much effort. Today, I am going to unlock the details on the Introduction to 2n4400. It is an NPN (negative-positive-negative) bipolar transistor which is mainly designed for general purpose amplification and switching applications. I'll cover each and everything related to this transistor, so you get all information in one place without roaming around on the internet. Let's get started.
