Hello everyone! I hope you all will be absolutely fie and having fun. Today, I will elaborate you about Introductio to NE556 timer IC. NE-556 is a lot stable monolithic device. We can use precise delays and oscillation by using this device. NE 556 is bsically an dual version of NE 555 timer IC. Timing is provided for each function using an external capacitor and resistor. There are two internal timers which operates independently. They just share common power supply and ground. For the falling or rising wave forms we can trigger or reset the entire circuit.
The trigger level and the threshold levels are usually one third and two third respectively. We can alter both of these level by using control pin of NE-556. If the input at trigger falls bel ...
Hello readers, I hope you all are doing great. In this tutorial, we will learn about the ESP-NOW protocol and how to communicate data between two ESP modules through ESP-NOW protocol and that is too without Wi-Fi connectivity.
What is ESP-NOW Protocol?
Fig. 1: ESP-NOW Protocol
ESP–NOW is a connectionless communication protocol that is used for sharing small data packets between two ESP boards. This protocol is developed by Espressif.
Features of ESP-NOW Protocol:
It is a low-power wireless protocol, which makes two or more ESP devices communicate directly with each other without using Wi-Fi.
ESP-NOW protocol does not require a handshake for establishing a connection but, they require pairing and once the devices are paired they can exchang ...
Hello everyone, I hope you all are doing great. In today's tutorial, we are gonna have a look at Linear Actuators and How Do They Work? There are many types of actuators available but today we are only gonna focus on Linear actuators.
If you got into any trouble then ask in comments and I will help you out. You should also try our Forum section which we have recently started and our experts will surely solve your issues. You should also have a look at How to use Arduino with Linear Actuator, if you are working on some automation project. So, let's get started with it:
What Is a Linear Actuator?
A linear actuator is a piece of mechanical equipment commonly used on industrial scale in brakes, stamping presses, and car jacks. It acts by using power t ...
In today’s tutorial, we’ll show you how to program the ESP32-CAM module. ESP32-CAM module is suitable for building basic surveillance or monitoring systems. Its price is quite reasonable. You can use it for lots of AI-based projects like object detection, face recognition etc.
However, many users face hard luck when setting up and uploading code to ESP32-CAM development boards. This tutorial will provide you with a guideline for successfully programming the ESP32-CAM.
Overview of the ESP32-CAM Development Board
The ESP32-CAM is a standalone development board that integrates an ESP32-S chip, a camera module, onboard flash memory, and a microSD card slot. It features built-in Wi-Fi and Bluetooth connectivity and supports OV2640 or OV7670 cameras with a resolution of up to 2 megapixels. ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to share Top 5 Reasons a Survivalist Should Be an Amateur Radio Operator. With 2021 setting in, are you well prepared to survive if the world goes down? We live in uncertain times, and the pandemic has taught us that what we plan today might not be applicable tomorrow. Simply put, like survivalists, we should be mentally and physically tough and all geared-up for emergencies, disruptions, and the breakdown of society. If you are currently living the survival mode, also known as the prepper lifestyle, you are heavily self-reliant. We expect you to have your backpack ready with all the right emergency tools and gadgets, such as a survival knife and a ham radio set. Read ...
Hello friends, hope you all are fine and having fun with your lives. Today, I am going to share on How to measure Frequency using Arduino board. Its quite a simple tutorial but is an essential one especially when you are working on some power related project. Because in Power projects, you have to measure the frequency of AC voltages. I was working on a project in which I have to do dimming of AC Lamp so in that project I have to measure the frequency of AC signal.
I have designed this project using Arduino UNO and have simulated in the Proteus software, which you all know is my favorite simulating software. :) The code is also quite simple which I have given below for download. The simulation is also included in download package but again I sugge ...
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 ...
Hey fellows, Welcome to another lecture in the signal and systems series in which we are moving towards another transform. Till now, we have studied the Laplace and z transform and we, therefore, know the basic purpose of transforms, that is, to convert the signal from one domain to another. In today's lecture, we will be discussing the Fourier Transform, and you will enjoy its information because now we have a clearer idea of what we are doing and what the purpose of this transformation of a signal is. Here are the key points that we are going to consider:
What is the Fourier transform?
What is the journey Fourier transforms from start to end?
How do you define the types of Fourier transform?
Why is the Discrete Fourier transform important?
Why is the fast Fourier transforms named so ...
Hi Friends! Hope you are doing well. We always strive to keep you updated with valuable information as per your needs and demands so you keep visiting us quite often. Today, I'll uncover the details on How to Install Outdoor Projector for Maximum Effect.
When you are in the middle of dealing with atrocities of life, you want a break that gives you both pleasure and relaxation at the same time. Putting yourself in a sheer peace differs from person to person, some love to fuel their car up and go for the long drive, other want to relax their muscles a bit and go for some game they love to play and some end up finding new ways of entertainment.
Thanks to technology that has made things easy more than ever before and turned out to be a solution ...
Hello friends! I hope you are doing well. Today, I am going to discuss the Bachelor degree in Engineering (B.Eng.). It is an academic degree of three to four years, and the start of your careers like designing the highways, machinery, building communities, working on technologies, innovative technologies, and creating new mechanical devices or tools. However, I will discuss the main branches of Engineering and their major subjects, scope of this degree, and top universities offer this degree programs.
Bachelor's degree in Engineering
Further, this degree is academically equal to the BSc ( Bachelor in Science) degree. It mainly aimed to provide technical skills to students. Universities also give many technical programs of applied sciences. But regu ...
