Hello everyone, I hope you all are fine and having fun with your lives. Today, I am going to share the next tutorial in this series of basic Arduino tutorials and it's named How to use Arduino Serial Write. In this tutorial, I have given an overview of How to use the Arduino Serial Write Command. In the previous tutorial, we have seen How to use Arduino Serial Read? in which we have read the data coming from the serial port.
While today we will have a look at how to send the data through a serial port in Arduino and for that, I am going to use the Arduino Serial Write command. It's also going to be a very simple and basic Arduino tutorial but if you are new to Arduino then you must read it completely as it will gonna help you out. I have also desig ...
Hello friends, I hope you all are fine and having fun with your lives. In today's post we are gonna see Interfacing of EasyVR with Arduino UNO. In the previous post, we have seen Getting Started with EasyVR Commander. It was quite simple and if you follow the steps carefully you wont stuck anywhere but still if you into some trouble i am here.
Now this tutorial is quite a quick and important one as it contains the real code using which we will control our robot. After adding the voice commands, now close the EasyVR Commander and open the Arduino Software. Connect the arduino board with computer and double check that your jumper J12 in on position SW. You should also read Training Error: Recognition Failed in EasyVR, if you got such error while ...
The article will cover essential aspects of fluid statics and pressure forces applied to the fluid. The article will start with the absolute pressure gauge and the variation of pressure with depth in different gravitational field manometers and barometers, respectively. Then I will explain the forces that deal with fluids, such as hydrostatic force, buoyant force, etc. So, dear friends, without wasting any time, let’s start.
Pressure
The definition of pressure according to fluid mechanics is as follows:
Pressure is the normal force applied by a fluid per unit area.
Unit of Pressure
The units of pressure Pascal is too small to deal with in practical cases. For instance,
Kilopascal: 1kPa=103Pa
Mega Pascal: 1MPa=106Pa
The three common pressure units used are standard atmosphere ba ...
Hello readers! Welcome to the next episode of the Deep Learning Algorithm. We are studying modern neural networks and today we will see the details of a reinforcement learning algorithm named Deep Q networks or, in short, DQN. This is one of the popular modern neural networks that combines deep learning and the principles of Q learning and provides complex control policies.Today, we are studying the basic introduction of deep Q Networks. For this, we have to understand the basic concepts that are reinforcement learning and Q learning. After that, we’ll understand how these two collectively are used in an effective neural network. In the end, we’ll discuss how DQN is extensively used in different fields of daily life. Let’s start with the basic concepts.

Hi Guys! Hope you’re well today. I welcome you on board. Happy to see you around. In this post today, I’ll detail the Introduction to Arduino Sensor Shield.
Arduino Sensor Shield is a board compatible with the Arduino Boards and comes with the standard header layout. It is used to connect sensors, servos, LCD with the Arduino board without soldering. This board is connected with the Arduino Board using the jumper wires.
I suggest you read this post all the way through as I’ll be discussing the complete Introduction to Arduino Sensor Shield.
Let’s get started.
Introduction to Arduino Sensor Shield
Arduino Sensor Shield is a board used to connect sensors, servos, LCD with the Arduino Board without the requirement of soldering.

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!

Hi readers! I hope you are having a great day and finding something new to learn. Today, the topic of our discourse is PCB Castellation and Castellated Holes.
Printed Circuit Boards (PCBs) are the core of nearly all electronic devices and are a structured platform on which components are mounted and interconnected. As electronics are moving toward more miniaturization, modularization, and mass production, PCB technologies must advance to be able to support these new requirements. Part of this advancement is the use of PCB castellations or castellated holes, a technology that supports small, modular board-to-board connections.
Castellated holes are tiny, plated half-holes on the border of a PCB. They allow one PCB, a module, or daughterboard, to be soldered onto another directly, much lik ...
There is no escaping from the fact that cutting-edge technological developments and evolving market innovations are pushing 3D printing into the mainstream. According to experts, the 3D printing market is expected to become a multi-trillion-dollar industry. It will rise from a $ 5 billion market to $55.8 billion by 2027. This is enough reason why many industries have started to embrace it. The 3D printing market has gained popularity due to the maturing business environment. And now that all sorts of businesses have picked pace after COVID-19, the 3D market has become quite a rage. And the market continues to experience massive success among home users and hobbyists. The number of 3D printers has doubled in the last few years. However, the combined value of the overall industrial/c ...
Hey Fellas! I hope you are enjoying your life. Today, I am going to share the 3rd chapter in the PCB learning series. In the last tutorial, we discussed Single-sided PCB in detail and today, we will have a look at the double-sided PCB. In double-sided PCB, the conductive copper layer is present on both sides of the board, unlike single-sided PCB where we have a conductive layer on a single side of the PCB. Thus, we can place electronic components on both sides of the double-sided board and normally use SMD components.Let's jump in and explore more about double-sided PCB:Double Sided PCBDouble Sided PCB is a type of PCB that has conductive copper layers on both sides of the board.
Simply put, double-sided PCB comes with two-sided traces or paths ...
Civil engineers have more power on the desktop—and in the cloud—than ever before. The 2025 generation of design platforms blends Building Information Modeling (BIM), traditional CAD drafting, GIS context, and AI‑assisted automation into one fast‑moving toolkit. Below is a plain‑language look at the best civil design software choices this year, what they do well, and how to pick the right match for your team.
What Makes Great Civil Design Software in 2025?
Connected BIM + CAD – Models, drawings, and data stay in sync across disciplines.
Open standards – Support for IFC 4, SAF, LandXML, and DWG keeps projects portable.
AI‑driven speed‑ups – Auto-classification, code checks, and alignment suggestions trim hours of manual work, such as in transportation engineering services
