Hi Guys! Hope you are doing great. Today, I am going to unlock the details on the Introduction to POS system. The POS stands for point of sale which is a process where a transaction is made when customers select some product and finalize it after checking out from the main window. It is very useful for keeping the track record of inventory and the number of sales made per day.
There are many benefits of using this method including better user experience, retention of customers, price customization of every product, and keeping the track record of the previous purchase history of the customers. This process refrains you from using old traditional methods of carrying out sale process in which cash registers were used.
I'll try to cover each and e ...
Knee milling machines are fundamental to many engineering and fab shop floors. To appreciate their usefulness, first define them by their unique Z-axis architecture. Unlike a bed mill where the head travels over a fixed bed, a knee mill is a vertical mill where the workpiece table is attached to a large cast iron knee.
The knee moves up and down along a column, exposing the X-axis (left/right), Y-axis (forward/back) from the horizontal table on top of the knee, and the spindle with the cutting tool hanging down from above. The spindle is held in a quill that can move up and down independent of the knee mill’s Z-axis. The knee is the primary vertical adjustment, but the quill carries out the detailed vertical motion of the cutting tooling. This mechanical layout gives knee milling machines ...
Hello geeks, Welcome to our new project. As most readers have already seen the coffee vending machine or maybe you are drinking coffee while reading this article and if you are a tinker or a geek, it must have come to your mind how to make a coffee vending machine on your own. In today's tutorial, we are going to learn how to make a Smart Coffee Vending Machine using Arduino with Proteus Simulation for the same.
We can use this project for an engineering project’s showcase for electronics, electrical engineering students, and can be used in offices as well.
Coffee is the second most popular drink in the world and it is one of the oldest beverages of the world. According to Wikipedia, more than 2 billion cups of coffee are consumed every day in the ...
Hello friends, I hope you are doing very well! In today's tutorial, we will set up a simulation environment for Ladder Logic Programming. It's our second tutorial in Ladder Logic Programming Series. In our previous tutorial, we have seen a detailed Introduction to Ladder Logic Programming and we have seen that this programming language is used for PLC controllers.
As PLC is an Industrial Controller, it comes with built-in relays/transistors(with protection circuitry) and thus is quite expensive as compared to microcontrollers/microprocessors i.e. Arduino, Raspberry Pi etc. Moreover, if you are working on a real PLC, you need to do some wiring in order to operate it. So, in order to avoid these PLC issues at the beginning, instead of buying a PLC o ...
Hello friends, I hope this article finds you happy, healthy, and content. Today, we are about to discuss one of the most commonly known types of transistors which you might have heard of many times when reading about transistors, the transistor under study is none other than the “Bipolar Junction Transistor’’, also known as BJT . In this article, we will go through the basics of the bipolar junction transistor including its meaning ,definition, types, characteristics, and applications. So, let's get started.
Definition of BJT
A BJT in its full form is written as bipolar junction transistor and we can define it as,
"A bipolar junction transistor is a three-terminal semiconductor device which is made up of two PN junctions within its structure a ...
Hey Guys! Hope you are doing great. Today, I am going to discuss the details on the Introduction to BJT (Bipolar Junction Transistor). It is an electronic component mainly used for amplification and switching purpose. As the name suggests, it is composed of two junctions called emitter-base junction and collector-base junction.
Don't confuse BJT with regular transistors. A transistor is a semiconductor device, comes with three terminals that are used for external connection with electronic circuits. A transistor is termed as a trans resistor which is used as switch or gate for electronic signals. Small signals applied between one pair of its terminals are used to control much larger signals at the other pair of terminals.
Actually, transistors are divided into two categories called u ...
Hi readers! Hopefully, you are well and exploring technology daily. Today, the topic of our discourse is TCS34725 Color Sensor. You may know about it, or it may be something new and different. It is a sophisticated module used to detect colors. It is highly precise and reliable in its work.
Featuring an integrated photodiode array and RGB filters, it is highly accurate in measuring red, green, blue, and clear light components. Enhanced by a built-in infrared-blocking filter for raising color fidelity against interference IR light, it has a built-in 16-bit ADC that ensures detailed and precise data output.
This sensor is communicated via the I2C interface, so it is compatible with microcontrollers like Arduino and Raspberry Pi. Its adjustable gain and integration time settings enable it t ...
Hello everyone. Today is a great day that we are going to put our focus on another type of PCB. So far in the previous articles, we have looked at high speed, metalcore, high density interconnect and the ceramic types of PCBs. In this article, we are going to introduce another type of PCB that might find great use in your day-to-day interaction with the printed circuit boards. it is very important for a designer to take note of how PCBs have evolved and how they have become an important aspect in the design of successful electronic devices. It has become hardly difficult to come across any time of an electronic device that does not involve the use of printed circuit boards.
In PCB boards you come across LEDs fixed in them, and due to the evolving w ...
Hello friends, hope you all are fine and having fun with your lives. Today, I am going to show you guys How to use C# Double Variable in your projects. In our previous tutorial, we have seen How to use C# Int Variable and we have also discussed about the term Variables in detail. So, I am not gonna discuss it again and gonna come straight to our topic C# Double variable.
It's my second C# tutorial in the series of C# variables. In the coming tutorials, I will discuss the remaining C# variables in detail. I have also provided the project code below but I would suggest you to do it on your own so that you get most out of it. Moreover, you should also have a look at Introduction to C# Windows Forms and How to use C# Control in Widows Forms as I am ...
