Hi friends, today we are going to learn a good technique to run multi outputs in sequence. In another word, when we have some output that is repeatedly run in sequence. In the normal or conventional technique of programming we deal with them individually or one by one which takes more effort in programming and much space of memory. So instead we can use a new technique to trigger these outputs in sequence using one instruction which will save the effort of programming and space of memory. In this article, we are going to introduce how to implement sequencer output instruction. And practice some examples with the simulator as usual. Before starting the article, we need to mention that, some controllers like Allen Bradley have sequencer output instruction and some has not like Siemens. So we ...
Hi readers! Hopefully, you are doing well and exploring something new. Every powerful machine has a secret weapon, a machine that few think about but is responsible for all speed, torque, and, relatively speaking, performance. That secret weapon is an incredibly engineered gearbox. Today, we discuss gearbox design.
Gearbox design and selection are amongst the most critical elements of mechanical engineering, as they involve how power will be best transferred between two rotating shafts. A gearbox changes speed and torque position from a power supply (usually a motor) to the required application. Gearboxes accomplish this through a series of different types of gears, in various configurations. Gearboxes allow machines to perform under various parasitic load conditions.
Gearboxes vary wide ...
Fluid mechanics is considered to be one of the essential branches of Mechanical Engineering. Fluid Mechanics comprises two words, fluid, and mechanics, with different meanings and research criteria. In this article, I will extensively introduce fluid mechanics and its importance in daily life. So without wasting any time, let us start:
Introduction to Fluid Mechanics
What is Fluid?
We remember in the early classes, we used to study three states of matter, and afterward, they became four named: Solid.Liquid.Gas. Plasma.
The definition of fluid is the state of matter that can be liquid or solid. We might have noticed that whenever the matter is in any stage, the criteria to know its state is to understand how much stress it can bear, and we name th ...
Hi Guys! Hope you’re well today. I welcome you on board. In this post, I’ll walk you through How to Optimize a PCB Panel Layout.
PCB panels are used in the manufacturing process to produce PCBs in large numbers. This not only reduces the overall cost but also makes the manufacturing process more efficient and reliable. PCB panelization is a manufacturing technique where multiple PCB designs are replicated on a single large board called a PCB panel. Then these individual boards are removed and depanelized from the panel to install them in the final product.
The number of panels is directly related to the overall manufacturing cost. To produce more panels, more cost will be required. However, it also depends on the shape of the board. If ...
There is no doubt that the traditional workplace has changed in a major way in the last few years. About half of companies now have remote workers. This means that managing a team looks different from what it ever did before. Facilitating the best of what a team has to offer, the synergies, the camaraderie, the collaboration, looks and feels different. It is sometimes difficult.
Those who manage remote teams are learning how to keep teams engaged and motivated, even as they work in isolation. Here are some of the techniques they are employing to keep their employees on track.
Regular Touch-Base Meetings
Working in the office made it easy and natural to casually ask questions, double-check information, and get feedback from colleagues. That ease made c ...
Our next step in the Raspberry Pi training program is to get zero tiers up and run on a Raspberry Pi 4. How to utilize a Raspberry Pi to measure internet speed and store the results in Grafana or Onedrive was the topic of the last piece. During the project, you will discover how to install ZeroTier on a Raspberry Pi and get it up and running. We will also learn how to set up a firewall to secure our network.
Components
Raspberry pi 4
Power supply
Ethernet or wifi
What is zeroTier
ZeroTier is a software that provides a streamlined web-based interface for constructing virtual networks connecting various gadgets. Somewhat akin to configuring a virtual private network on a Raspberry Pi, these networks exist only in cyberspace. The process o ...
Following up on our Raspberry Pi programming course is the next lesson. In the previous post, we learned how to construct an FM radio using a Raspberry Pi. Analog FM broadcasting's circuit construction was also studied in detail. How to use a Raspberry Pi as an internet speed meter and save the data in Grafana or Google Drive is the subject of this article.
You can use this article if you want to keep track of how your downloads, uploads, and ping speeds change over time, and it's easy to use. In addition, you can use this to determine when your internet is at its busiest or if your internet speed has deteriorated. We'll demonstrate how to use Ookla's Internet speed test command-line interface in conjunction with Python code to create an internet speed meter.

Thank you for joining us for yet another session of this series on Raspberry Pi programming. In the preceding tutorial, we constructed a personal Twitter bot using Tweepy, a Py framework for querying the Twitter application programming interface. We also constructed a Response to robot mentions that would post a response to everybody's tweet mentioning it with a certain keyword. However, in this tutorial, we will implement a security system using a motion sensor with an alarm. This is what it looks like:
PIR Motion Sensors can be implemented with RPi by understanding how it is connected to a Raspberry Pi. Whenever the motion sensor detects human movement, an alarm is triggered in this project and the LEDs blink. You may create a simple motion-det ...
Thank you for joining us for yet another session of this series on Raspberry Pi programming. In the preceding tutorial, we integrated a real-time clock with our raspberry pi four and used it to build a digital clock. However, In this tutorial, we will construct your personal Twitter bot using Tweepy, a Py framework for querying the Twitter application programming interface.
You will construct a Response to mentions robot that will post a response to everybody's tweet mentioning it with a certain keyword.
The response will be a photo we will make and put any text over it. This message is a quote you will acquire from a 3rd application programming interface. Finally, we will look at the benefits and drawbacks of bots.
This is what it looks like:

Introduction
Thank you for joining us for yet another session of this series on Raspberry Pi programming. In the preceding tutorial, we implemented a speech recognition system using raspberry pi and used it in our game project. We also learned the fundamentals of speech recognition and later built a game that used the user's voice to play. However, this tutorial will integrate a real-time clock with our raspberry pi four and use it to build a digital clock. First, we will learn the fundamentals of the RTC module and how it works, then we will build a digital clock in python3. With the help of a library, we'll demonstrate how to integrate an RTC DS3231 chip with Pi 4 to keep time.
Real-Time Clocks: What Are They?
RTCs are clock units, as the name ...
