Hello friends, I hope you all are doing great. Welcome to the 3rd lecture of Section 5(ESP32 Sensors) in the ESP32 Programming Series. We have already discussed the two built-in ESP32 sensors i.e. Hall Effect Sensor and Capacitive Touch Sensor. Today, we are going to discuss the 3rd and final built-in ESP32 sensor i.e. Internal Temperature Sensor.
ESP32 Internal Temperature Sensor is used to calculate the temperature of the ESP32 core. So, we can't use it to measure the ambient temperature (the temperature of the atmosphere), for that, we need to use embedded temperature sensors i.e. DS18B20, DHT11, BMP280 etc. We will first discuss the basics of this Internal Temperature Sensor and then will design a code to monitor the change in temperature by changing the frequency of the ESP32 CPU.

Hi Guys! Hope you are doing well. I am back to give you a daily dose of useful information. Today, I'll discuss the details on the Introduction to Raspberry Pi 3 B+. It is a small board computer, introduced by Raspberry Pi foundation in 14th March 2018 and is the most recent version of the Pi boards.
It is a modified form of its predecessor Raspberry Pi 3 B that was introduced in 2016 and came with CPU, GPU, USP ports and I/O pins. Both versions are almost same in terms of functionality and technical specifications; however, there are some exceptions in the B+ model as it comes with USB boot, network boot, and Power over Ethernet option that are not present in the B model.
Technology has been evolved over time with the purpose of making lives ...
Generally, Psychology is a wide sphere of knowledge and has a great opportunity to select from a great selection of ideas. It is necessary for the students to pay attention to some general ideas and then narrow them down. It is a fact that psychology is a very difficult subject for ordinary students and it is compulsory to write down all about it in the assignment.
It is very possible for a lot of students to know the manner in which they want their term papers to look. However, it is not easy to arrive at a topic on which the term paper will rely. This may be easier with other subjects, but not with term papers in the curriculum of psychology.
Psychology Semester Papers
We have several things that you will have to do with the topic. You will have to show that you are aware of the e ...
Greetings, and welcome to the next tutorial in our series on programming for the Raspberry Pi 4. The previous tutorial showed us how to connect a 4x4 keypad to a Raspberry Pi 4. In the previous tutorial, we examined the inner workings of the 4-by-4 keyboard; in this one, we'll use the MCP3008 and the LM324 Op-amp IC to connect a joystick to the Raspberry Pi 4. The Joystick is the primary input device for many gaming systems. The Joystick we'll be connecting to the Raspberry Pi today plugs into a USB port, but there are plenty of situations when having access to the Pi's GPIO pins would be useful. We'll review the steps for preparing the circuit for each interface technique and creating a corresponding python script.
So let’s dive in!

The first law of thermodynamics is also known as the Conservation of energy Principle. I will explain what is energy principle is and the following are some important points of the Energy Principle:
The energy principle can be described as the following equation:
Ein-Eout=∆E
I will exemplify the energy equation through a simple example. For instance, the rock fell from the cliff and while falling from the cliff the rock gained speed and the speed doubled while coming down. The potential energy is converted into kinetic energy as the rock is falling from height. Here the air resistance is negligible here. All these factors confirm the conservation of energy principle.
One of the simple examples of the Conservation of Energy Principle in our daily life is the man who has a lot of ...
Hi Friends! Hope you’re well today. I welcome you on board. In this post, I’ll detail how Innovative Engineering Solutions Improve Efficiency in the Offshore Oil Industry.
Despite ambitious global goals to reduce carbon emissions, fossil fuels such as gas and oil still provided over 80% of the world’s energy in 2019. The petroleum industry is still vital for global energy supplies, and, according to the International Labor Organization, directly employs almost 6 million people around the world.
To improve levels of safety and productivity while at the same time meeting ambitious targets for a low-carbon future, the industry is making significant changes. Innovative technologies are required to maximize the recovery of fossil fuels while at the ...
Hello friends, I hope you all are doing great. In today's tutorial, we are going to have a look at few Common Operators in C#. It's 4th tutorial in C# series and before going forward, we have to first understand the working operation of these C# operators.
We have a lot of operators in C# but I have discussed few of them, which are most commonly used. If you got into any trouble then ask in comments. So, let's get started with Common Operators in C#:
Common Operators in C#
Operators are used to create a link, relation or operation between two entities/variables. Few of these C# operators are as follows:
Assignment Operator ( = )
Arithmetic Operators ( + , - , * , / , % )
Comparison Operators ( == , != , > , < , >= , <= )
Co ...
Web scraping is an invaluable skill in today's data-driven world. However, it must be performed responsibly and efficiently for optimal results. Here are our top 9 best practices that promise smooth execution of your upcoming web scraping projects.
Setting the Stage: Understanding Basic Rules of Python-based Web Scraping
Diving into web scraping can be a truly exciting venture, but it's crucial you understand the basic rules first, and have a handle on Python itself
. Before coding your web scraping script in Python:Do enough research on the site or API you intend to scrape.Know what kind of data is available and how that data is structured.Analyzing websites also aids in understanding the HTML tags for effective extraction.Have clarity on wheth ...
Hello friends, I hope you all are doing great. In today's tutorial, I will show you how to perform Simplest Half Wave Rectification in Proteus. In this tutorial, we will design a simple Proteus simulation, where we will use a diode for half-wave rectification.
Before designing the Proteus simulation, we will first have a theoretical overview of Half Wave Rectification as it's always the best approach to read theory before practical (Proteus Simulation). So, let's get started:
What is Rectification ???
Rectification is an electrical process, used to convert Alternating(AC) Voltage into Direct(DC) Voltage using a circuit called rectifier.
The Rectification process is always carried out using diodes, as we know diodes allow the current to flow in one direction only, thus t ...
Hello friends, I hope you all are doing great. In today's tutorial, I am gonna discuss How Point-to-Point Tunneling Protocol (PPTP) Works. Online security is more important than ever. With hackers and brute force attackers, it feels like your private data is constantly at risk. One way to protect your security online is by using a VPN.
VPNs may use several protocols. These protocols are like the language that's used by your computer and the VPN server as they communicate. Some protocols are faster than the competition while others prioritize security.
One of the oldest, yet still popular, VPN protocols is Point-to-Point Tunneling Protocol, or PPTP. It was introduced in 1995, and though newer protocols have since usurped its place as the greatest, ...
