Thank you for being here for today's tutorial of our in-depth Raspberry Pi programming tutorial. The previous tutorial demonstrated the proper wiring of the photoresistor sensor to the GPIO pins. Finally, we learned how it might be included in a Python script for data collection and analysis needs. We also looked at the functions of each component in the circuit. However, I'll walk you through installing a Pi 4 Print Server in this guide. While installing the program is straightforward, setting it up so that a Windows network can locate the print server requires a little more effort. Rather than spending hundreds of dollars upgrading to a laser printer, you may easily upgrade your current USB printer to laser quality by installing a print server.
Because of this software, you no longer ha ...
Hello readers, we hope you all are doing great. Welcome to the 4th lecture of Section 5(ESP32 Sensor) in the ESP32 Programming Series. So far, we have discussed the ESP32 built-in sensors in this section. Today, we are going to interface an external embedded sensor(i.e. PIR Sensor) with the ESP32 Microcontroller board. At the start, we will discuss the basics of a PIR Sensor(HC-SR501) i.e. its pinout and working. After that, we will design a simple project to detect the motion with a PIR sensor and ESP32. Finally, we will display the motion detection results on the ESP32 WebServer.
We will use ESP32 interrupts to detect the motion. Interrupts are used when a microcontroller needs to continuously monitor an event while executing other tasks at the same time. We have already posted a tuto ...
The eCommerce industry, which has already experienced year-over-growth for the past five years, gained a monumental boost after the pandemic made online shopping mainstream. Today, there are more than 20 million eCommerce businesses operating worldwide, and new companies open shops every day.
The majority of these companies need skilled developers and engineers to build safe and robust eCommerce sites to house their businesses. If you are interested in specializing in eCommerce development, you would be remiss to ignore the advantages and disadvantages of each payment gateway option.
Payment gateways allow online customers to purchase products seamlessly and securely. However, they are not all created equal. As an engineer or site developer, you s ...
Hola students! Welcome to the new Python tutorial, where we are learning about OOP. We all know why OOP is important in programming. In the previous lecture, a detailed overview of classes and objects was discussed. We are moving towards the next step of learning where our focus will be on inheritance. Yet, programming also contains inheritance. We have all read about inheritance in real life and are aware of the concepts surrounding it. This time, we will discuss these concepts according to the workings of the classes and related entities. The concept of inheritance is the same in both scenarios, and with the help of interesting examples, the practical implementation of inheritance will be shown to you, but first of all, it would be interesting to know about the main headings that will be ...
Hello everyone, I hope you all are doing great. In today's tutorial, I am going to share a new version of Heart Beat Sensor Library for Proteus i.e. version 2.0. I have already posted the First Version of the Heart Beat Sensor Library for Proteus in which you can use the TestPin and if it's HIGH then a single heartbeat pattern will start. So, if you use that library, you will always get the same result for your heartbeat. But in this 2nd version, I have added variable heartbeat depending on the value of TestPin. I will show you in detail, how to do it.
I have also posted a project Heart Beat Counter using Arduino in which I have shown you How you can use this sensor and count your Heart Beat. So, let me show you How you can use this new Heart ...
Hello Friends! I hope you all are doing well. Today, I am going to share with you a very basic and detailed tutorial on What is Chemistry? We will also discuss Chemistry types, popular Chemistry books, famous Chemists and their great inventions in the field of Chemistry etc. When you hear the word Chemistry, you may think, it is only concerned to the study of chemicals, dangerous substances etc. But let me surprise you, Chemistry is also known as the Central Science means it is the insight study of almost everything around us. I just remembered very comprehensive Chemistry definition by American Chemical Society, “Everything you touch, see, smell and hear involves Chemistry and chemicals”.
Scientist divided Physical sciences in 5 major discipline ...
Oil platforms represent some of the most challenging and potentially hazardous work environments on Earth. These massive structures, standing alone in vast expanses of ocean, house hundreds of workers who extract petroleum from beneath the seabed. The question of safety on these installations is complex, involving multiple layers of risk management, regulatory oversight, and technological advancement
that have evolved significantly over decades of offshore drilling operations.
Understanding the Risks
Offshore oil platforms face unique safety challenges that distinguish them from land-based industrial facilities. The marine environment presents constant threats from severe weather conditions, including hurricanes, storms, and high seas that can damage equipment and endanger personnel. T ...
Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at Future of Online PCB Industry in 2019. The first printed circuit board was created by the Paul Eisler in 1943 until its creation it has become more sophisticated and advanced. Nowadays there are many types of PCB like single-sided, double-sided, multilayer PCB are exiting. The current PCB is available at less cost and more designing options than its creation time. If we look ten years back different PCB design like HDI (High-Density Interconnector), microvias, and Field Programmable Gate Array were considered most expensive but nowadays they are easily available to all over the world.
With the new inventions of electronic industries, the use and demand of P ...
Introduction
Thank you for joining us for yet another session of this series on Raspberry Pi programming. In the preceding tutorial, we implemented a speech recognition system using raspberry pi and used it in our game project. We also learned the fundamentals of speech recognition and later built a game that used the user's voice to play. However, this tutorial will integrate a real-time clock with our raspberry pi four and use it to build a digital clock. First, we will learn the fundamentals of the RTC module and how it works, then we will build a digital clock in python3. With the help of a library, we'll demonstrate how to integrate an RTC DS3231 chip with Pi 4 to keep time.
Real-Time Clocks: What Are They?
RTCs are clock units, as the name ...
Marketing is the cornerstone of any business. Yet, so many business owners struggle to find new and innovative ways to promote their business to potential consumers. In an ever-evolving economy, marketing your endeavor is going to involve plenty of thinking outside the box. We no longer live in a world were a simple ad-campaign or coupon promotion is enough to drive eyeballs to a site or feet through the door. If you’ve been looking for new ways to market your business without breaking the bank, there is one new method you should try: text to speech technology. Not only is it one of the freshest ways to market your business, but it is one of the most affordable. Let’s take a look at how text to speech technology can be used to market your business. ...
