Hello Friends! I hope you all are doing well. Today, I will share with you a very comprehensive tutorial about What is Science? Here, we will discuss science branches, importance of science in our life, popular science books, famous scientists and great inventions in the field of science. Science is derived from a Latin word’ Scientia’ means knowledge. When we are saying the word Science, refers to the study of every simple or complex phenomena occurring around us. For example, from the food we enjoy, to the cloth we wear, everything is science.
Now let's get to know what is Science?
What is Science?
Science is the most important platform of knowledge and understanding the world. It has improved the quality of almost every field of ...
Hello friends, hope you all are fine and having fun with your lives. In today's tutorial, we are gonna see Color Detection in Images using MATLAB. In the previous tutorial, I have posted about How to Detect Circles in Images using MATLAB in which we have detected objects based on their geometrical figure means either they are circle or not but today we are gonna distinguish objects based on their color i.e. whether they are red colored or green colored etc. Its a quite simple tutorial and comes in the basic category. We will first detect the color and then will create a boundary around that object and will also show its XY coordinates as well.
Image processing is an important tool of MATLAB. We can quite easily do the image processing in it using ...
Hello friends, hope you all are fine and having fun with your lives. Today, I am going to start a new series of tutorials on C++ Programming. and here's my first tutorial in this series which is Introduction to C++. I am gonna share a lot of tutorials in this series in future, in which I am gonna explain all about C++. In the initials tutorials, we will cover the basics of C++ Programming and later on we will also cover the pro concepts of C++ Programming.
I am planning on posting around 20 to 30 tutorials in this C++ Programming series, and I am quite sure that it will cover all about C++ and if you are a new learner then it will help you quite a lot.. I have started this series on a request of one of my readers. He suggested me this idea and I l ...
Hi Friends! Hope you’re well today. I welcome you on board. Today, I’ll walk you through the Introduction to INA219.The INA219 is a current sensor module that incorporates the I2C protocol for submitting the data obtained through sensing current, voltage, and power. It is a bi-directional zero drift current/ power sensing module mainly used in digital multimeters and power profilers.
I suggest you read this post all the way through as I’ll detail the complete Introduction to INA219 covering datasheet, pinout, features, and applications.
Let’s get started.
Introduction to INA219
INA219 is a current/power sensor module mainly employed to sense the power, voltage or current where up to 128 samples can be averaged together to get filtering in noisy environments. This data is then s ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge with all of guys about Introduction to IRF540. It is basically an N-Channel power Metal Oxide Silicon Field Effect Transistor (MOSFET) and operates in enhancement mode.
MOSFET is a lot sensitive in comparison to an FET (Field Effect Transistor) due to its very high input impdence. IRF540 can perform very fast switching as compared to the normal transistor. It is based on HEXFET technology and operates on the temperature ranging from -55 degrees celsius to 175 degree celsius. If we need some switching application between different signals or to perform any of amplification process, MOSFET IRF540 will be the best option in this case bec ...
PWM stands for Pulse-Width Modulation. Once the switching frequency (fsw) has been chosen, the ratio between the switch-on time (TON) and the switch-off time (TOFF) is varied. This is commonly called duty-cycle (D). The duty cycle can be between 0 and 1 and is generally expressed as a percentage (%).
D = TON / (TON + TOFF) = TON x fsw
The variation of the pulse width, made at a high frequency (kHz), is perceived as continuous and can be translated into a variation of the rotation speed of a motor, dimming a LED, driving an encoder, driving power conversion, and etc. The use of PWM is also widely used in the automotive sector in electronic control units (ECU - Electronic Control Unit) to manage the energy to be supplied to some actuators, both fix ...
Hi readers! Hopefully, you are doing well and exploring something fascinating and advanced. Imagine that particles can pass through walls but not by breaking them down? Yes, it is possible. Today, we will study Quantum Tunneling.
Quantum tunneling may be one of the strangest and illogical concepts of quantum mechanics. Quantum Tunneling proves the phenomenon of particles like electrons, protons, or even whole atoms percolating through the energy barrier of potential energy, although they do not appear to have sufficient potential to slide over it. The classical physics version of this ball at this point would merely reverse.
Nevertheless, in the quantum realm of things, particles now act like waves, and waves can pass through and even over barriers with some nonzero probability of the pa ...
Hello everyone, in today's post we are gonna have a look at how to interface temperature sensor Dallas 18B20 with Arduino. There are many temperature sensors available in market like LM35, DHT11 etc but personally I like Dallas18B20 most of all, as it gives the most accurate result up to four decimal points. It operates on single wire and sends all data through this wire. Another advantage of this wire is you can interface multiple sensors with a single data line. You should also have a look at How to use 18B20 in Proteus ISIS.
In today's post, we are gonna get value from this sensor and then print it over the Serial Terminal as well as LCD. We will get the values in degree centigrade. Its not much difficult to interface 18B20 with arduino and als ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to TIP121. The TIP121 is an NPN Darlington pair transistor. It exists in a TO-220 casing and creates for normal amplification and less moving speed switching submissions. Like other transistors, it has three pinouts emitter, base, and collector. The central part this transistor which is known as the base is thinner in size and other two emitters and collector has larger areas.
Transistors are playing an important rule in our electronic circuits and industries. Every electronic device like mobile, radio, LCD, etc all these have different types of transistors. Like other transistors, TIP121 is performing an important rule in electron ...
Greetings, and welcome to today's tutorial. In the last tutorial, we learned how to construct a system for tallying individuals using Raspberry Pi, astute subtraction, and blob tracking. We demonstrated the total number of building entrances and exits. Feature computation and HOG theory were also discussed. The tests proved that a device based on the raspberry pi could effectively function as a people counting station. One of the many benefits of the Pi 4 is its internet connectivity, which is especially useful for home automation projects due to its low price and ease of use. We're going to see if we can use a web page's buttons to manage our air conditioner today. With this Internet of Things (IoT) based home automation, you can command your home gadgets from the comfort of your couch. T ...
