Hello friends, I hope you all are having fun. Today, I am going to share the 9th tutorial of Section-III in our Raspberry Pi 4 Programming Course. In the previous tutorial, we interfaced an air pressure sensor BMP180 with Raspberry Pi 4. In this tutorial, you'll learn how to interface an MQ-2 gas sensor with a Raspberry Pi 4. Many apartments, residences, and workplaces rely heavily on these gas sensors to detect smoke or gas and alert the appropriate personnel in an emergency. In addition to gas and smoke, this sensor is sensitive to various odorous gases.
Project DescriptionToday, we will interface a gas sensor MQ-2 with Raspberry Pi 4 and will display the values on Raspberry Pi Console Window.

Picture it. You’ve had a stroke of genius and your idea could possibly revolutionize the healthcare industry. Or, perhaps you’re on the brink of inventing something that could eradicate carbon emissions from the environment once and for all. As an engineer, there is no limit to the solutions you can develop to help humankind. But how do you protect your ideas and research? How can you present your concept to investors or to the public without running the risk it might be stolen?
If you’re in the brainstorming or testing phase of an engineering marvel, you’ve got to take every precaution to protect your intellectual property from theft. To this end, here are some ways you can safeguard your engineering projects and research so you can rest assured you retain full ownership in later stag ...
Hello everyone! I hope you will be absolutely fine and having fun. Today, I am going to give you an Introduction to 2N2222. It is the most commonly used Negative-Positive-Negative (NPN) Bipolar Junction Transistor (BJT) available in the market now a days. 2N2222 can be used for different purposes e.g. switching and amplification of analog signals. I hope you have enjoyed the previous post on Introduction to ULN2003.
The major functional area of 2N2222 is enclosed in TO-18 package. Due to the low cost and small size it is the most commonly used transistor. One of its key features is its ability to handle the high values of currents as compared to the other similar small transistors. Normally it is capable of switching a load current of 800mA whic ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to Create a Registration Form in ASP.NET Core. It's our 13th tutorial in ASP.NET Core series. In our previous lecture, we have seen How to use Tag Helpers in ASP.NET Core and have also discussed link, image & environment Tag Helpers.
Today, we will have a look at Form Tag Helpers and with their help we will design a simple Registration Form in ASP.NET Core. It will be a quite lengthy tutorial so if you got into any trouble, then ask in comments. So, let's create our Registration Form:
Create a Registration Form in ASP.NET Core
Let's create a new action method named Registration, in our Home Controller clas ...
Hello friends, in today's post we are gonna have a look at Interfacing of Keypad with 8051 Microcontroller in Proteus ISIS. In the previous project, we have seen the Interfacing of LCD with 8051 Microcontroller and I have told there that LCD is a great debugging tool as we can print our data on it and can display different values and that's what is gonna done in today's post. Today, I will get the values from keypad and then question is how to know that we are getting the correct values. So in order to do so, we will display these values over LCD. So, that's how we are gonna use LCD as a debugging tool. As the debugging is concerned, there's another great tool for debugging which is called Serial port, we can also display these values over to Seri ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to share a new Rain Sensor Library for Proteus. I have got a lot of requests for designing this sensor. So finally it has been designed by our team and is ready to use in your Proteus Simulations.
Rain Sensor, as the name shows, is used for detection of rain and is common sensor used in Embedded Systems Projects. Both analog and digital rain sensors are available these days but we have only designed the digital Rain Sensor. It will give digital output and its output will be HIGH when there's rain and will remain LOW if it won't detect any rain.
As Proteus is a simulation software and we can't actually bring the rain so that's why I have placed a TestPin. If you apply H ...
Hello readers, I hope you all are doing great. Today, we are going to start the second section of the ESP32 tutorial series and today's our first tutorial, where we will have a look at How to Create a Web Server with ESP32. In our previous tutorial, we introduced you to the basics of the ESP32 microcontroller. where we discuss How to set up Arduino IDE to program ESP32. In this tutorial, we will discuss creating a web server using the ESP32 module.One of the most interesting features of the ESP microcontroller series is its wireless connectivity via WiFi & Bluetooth. Wireless connectivity protocols supported by ESP32 are:
Wi-fi: 802.11b/g/n/e/i
Bluetooth : BLE(Bluetooth low energy) and V4.2
What is a Web server?
A web server is software or hardware that stores, processe ...
Hello friends, hope you all are enjoying and having fun. In today's tutorial, we are gonna see How to design a Multiple LED Flasher Project using 555 Timer in Proteus ISIS. In our previous tutorial we have seen How to design a LED Flasher Project with 555 Timer in Proteus ISIS, in which we have flashed single and double LEDs. In today's post, I am gonna extend that previous tutorial and will see How to flash multiple LEDs with 555 Timer in Proteus ISIS.
Its quite a quick tutorial, as I don't have much material on it and its also quite simple so no much explanation is required. The complete project is given at the end for download but again as I always mention, try to design it by yourself, so that you get some knowledge out of it.This type of proj ...
Hello friends, i hope you all are fine and enjoying. Today i am going to share a new tutorial which is Brush-less DC motor. The basics of DC motor have been explained in one of my previous tutorial which was named as Difference Between DC and AC motors in that tutorial i explained in detail the basics of a DC motor, its construction and working.
Now in today's tutorial i am going to share a tutorial on one of the type of DC motor which is Brush-less DC motor. Brush-less DC motor is commonly known as Electronic Commutated motor. It is in fact a synchronous motor. From the word DC, one thing becomes clear that the supply voltage will be DC but as i mentioned in the previous line that it is a synchronous motor then, it will need AC supply to run. So ...
The cloud software industry has begun developing new working models that have been especially needed during the pandemic. However, even though the pandemic is almost neutralized, the cloud market continues to grow. According to a new Forrester report, global software spending will continue to rise, reaching a CAGR of 10.3% from 2021 to 2023.
Therefore, in this article, we will learn more about cloud technologies and their trends.
What is SaaS?
Let's start with the definition of saas development
. This is a special software model that is provided on a subscription basis. And most often it is a cloud solution. Such a concept as software as a service is deciphered.
