In the past, graphic designers had limited choice of graphic design tools. There were only 3-5 great design tools for professional work. This has all changed with free and open-source platforms making it easy to design what you want, wherever you want it. Also, many of these tools are cross-platform too, meaning you can whip up some quick designs on your Android or iOS device. Because the sheer number of available tools makes it harder to pick the best one, we are going to look at 5 great ones that you should be using right now.
Adobe Illustrator
Almost all designers agree that Adobe Illustrator is the best tool for creating vector graphics. You can use the software to create artwork, logos, infographics, artwork, icons, and pretty much anything ...
Hello friends, I hope you all are doing well. Welcome to the 11th tutorial of our Raspberry Pi programming course. In the previous chapter, we have seen how to regulate the speed of a Stepper motor with Raspberry Pi 4. Today, we'll work on the servo motor and will control it with RPi4. So, let's get started:
Components Required:We will need the following components to control Servo Motor with Raspberry Pi 4:
Raspberry Pi 4.
Servo Motor.
Male-to-female jumper wires.
What is a servo motor?
A Servo Motor is a simple DC motor with a position feedback Control System and a gearbox.A Servo Motor's primary advantage is its ability to maintain its shaft's angular position at any desired angle i.e. if we want to keep our shaft at 67 degre ...
Hello friends, I hope you all are having fun. Welcome to the 10th tutorial of our Raspberry Pi programming course. In the last chapter,
PWM was utilized to regulate the DC motor's speed and direction
with a motor driver L293D. In this chapter, we'll advance our skills with PWM and use it to control a stepper motor using the same motor driver L293D.Here's the video demonstration of this project:Let's get started:
Components RequiredHere's the list of components, which we will use to control the speed and direction of Raspberry Pi 4:
Raspberry Pi 4.Stepper Motor.
Motor Driver IC(L293D).
Jumper wires.
9V Battery.
Breadboard.
The Raspberry Pi with desktop is required for this project. An SSH connection can be made, or the RPi can ...
According to NASA, areas in the north of the U.S will experience higher rainfall, increasingly extreme hurricanes, and sea levels will rise by about eight feet by 2100. With climate change, extreme weather events have become much more frequent, and their magnitude has increased globally. This scenario presents a significant risk to server rooms and data centers by increasing the likelihood of water and fire damage.
Can Your Data Center and Business Recover After a Natural Disaster?
Data loss or inaccessibility after a natural disaster is a significant concern. After Hurricane Sandy in 2012, data centers in Manhattan had to extract water from the generator rooms and restore switchgear to become operational. In the U.K., flooding in Leeds caused im ...
The rapid adoption of digital transformation across industries has seen several organizations implement AI and Big Data capabilities to enhance their competitive advantage. Businesses, large and small, now leverage data to guide business operations and make critical company decisions.
The kind of data generated in every business environment varies, and these data sets only become useful once they are harnessed to give useful insights. Data engineers are the professionals often tasked with building and maintaining key systems that collect, manage and convert these data sets.
The huge amount of data generated in different industries has expanded the data engineering profession to cover a wide range of skills, including web-crawling, distributed comp ...
Hello friends, I hope you all are doing well. Welcome to the 9th tutorial of our Raspberry Pi programming course. In the last chapter, we generated a PWM signal from our Raspberry Pi to control the brightness of an LED. We also studied different functions used in Python to perform PWM. In this chapter, we'll get a bit advanced with PWM and use it to control the speed and direction of a DC motor with the help of a motor driver IC.
To control the speed & direction of the DC Motor, we will:
Design a Circuit Diagram.Write Python code.
Components RequiredWe will use the following components to control the DC motor speed:
Raspberry Pi 4.DC Motor.Motor driver IC(L293D).Breadboard.
Jumper wires.
Controlling DC Motor speed wi ...
Hello friends, I hope you all are doing great. It's the 8th tutorial in our Raspberry Pi programming course. In the previous lectures, we interfaced LCD 16x2 and Keypad 4x4 with Raspberry Pi 4. In this chapter, we are not going to interface any external module with Pi, instead, we'll create a PWM signal in the raspberry pi using Python. Let's get started:
Components RequiredWe are going to use the below components in today's PWM project:
Raspberry Pi 4.
LED.
A resistor of 330 ohms.
Breadboard.
Jumper wires.Before going forward, let's first understand what is PWM:
What is PWM?
In PWM(Pulse Width Modulation), we simply turn on and off our power supply at regular intervals and thus ...
Hi Friends! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through Cloud Computing Services.
The requirement to process and store data varies from business to business. Some organizations can handle data in on-site data centers. They have a team of experts who handle IT infrastructure and install, maintain and upgrade hardware based on the availability of data. This approach is expensive, no doubt. Some companies, however, don’t accept this model. They prefer cloud computing which is the availability of on-demand IT infrastructure over the internet. This model sets them free from handling and managing on-site data centers, instead, everything is managed and controlled by the cloud service providers. End users only pay for the computing services they use. ...
