EG Projects — Sun, 30 Mar 2025 22:20:47 +0000

In this tutorial, we’ll learn how to use device-to-device (D2D) communication to make daily life a little simpler. For example, you’ll be able to control household appliances, such as the coffee machine, a light switch, or the AC — and do so from inside your vehicle. So, if you’re arriving home one evening, the presence…

10 Real Life Instances of Internet of Things (IoT) in Use

Neha Rastogi — Tue, 05 Nov 2024 09:51:15 +0000

It goes without saying that technology is highly responsible for transforming the world around us in so endless number of ways. Not only it’s growing at a faster pace but it’s also gradually leading us to a smarter and better future. The term that has lately become the talk of the town is Internet of Things i.e. IoT. We are completely surrounded by so many applications of IoT in our daily lives but most of us are not aware of them. Interestingly, IoT was coined in 1999 by Kevin Ashton, a British entrepreneur, while he was working in his lab.

What to expect from microcontrollers in 2023

Nikhil Agnihotri — Fri, 17 Mar 2023 00:59:06 +0000

Microcontrollers are the workhorse behind most embedded systems. They serve as a compact integrated circuit (IC) designed to govern a specific operation in an embedded system. The programmable firmware used in these tiny computers is ideal for and fits well into several applications. Microcontrollers are neither too specific, like application-specific integrated circuits (ASICs), nor too…

How to achieve longer MCU battery life with low power sleep mode

Ayush Jain — Thu, 28 Jul 2022 22:02:37 +0000

There are generally six power modes in an MCU: Run: In full run mode, an MCU consumes full current. This mode is best suited for applications where power efficiency is not essential. Doze: As we know, power increases proportionally to the frequency. Therefore, we can conclude that higher clock speeds tend to higher power consumption.…

What is an embedded system?

Preeti Jain — Wed, 16 Mar 2022 10:50:07 +0000

If we look around, we will find ourselves to be surrounded by computing systems. Every year millions of computing systems are built destined for desktop computers (Personal Computers, workstations, mainframes and servers) but surprisingly, billions of computing systems are built every year embedded within larger electronic devices and still goes unnoticed. Any device running on electric power either already has computing system or will soon have computing system embedded in it.

USB (Universal Serial Bus): an overview

Bijal Parikh — Sun, 06 Mar 2022 15:59:35 +0000

What is USB? UNIVERSAL SERIAL BUS What does it do?It connects your laptop or PC to the peripheral devices attached to it.How does it communicate?You attach the device using a cable to PC and communication is initiated within a fraction of seconds. However, what looks easy on our end is a complicated process in the USB system. It may be single step in our stride to attach the device and start working but for the system it’s entirely a different picture. In that fraction of second after the device is attached, it initiates step by step process to make communication possible. It starts right from alerting the PC about the attachment, change in voltages at ports, then addressing the devices, gathering the information, loading the drivers and finally communication. Let’s understand each of these steps in detail to get a crystal clear picture about the working of USB.

Invention Story of Slot Machines

Samidha Verma — Mon, 17 Jan 2022 20:24:13 +0000

Have you ever thought who could be the father of the glorious machines that make most of the casino revenues these days? A casino owner, a researcher, a young lad interested in gambling? None of these. It was a car mechanic who changed the face of gambling entertainment. Charles Fey from San Francisco came up with the first ever slot machine in the year 1887. Until 20th century term ‘slot machines’ was used not just to address gambling devices but also the automatic vending machines. These machines were called by unusual named like one armed bandit and fruit machine. Before your imagination starts running wild with the names, let me tell you that it is because prior to Fey’s invention, there were some poker machines that allowed the users to win free drinks or cigars on hitting the winning combination. These were also known as trade simulators because they paid winners in merchandise.

Insight – How Head Phone TRS Connector or Jack works

Ashutosh Bhatt — Mon, 17 Jan 2022 17:13:28 +0000

Ever wondered how are wires connected to a connector. How different number of wires are connected to segments of the connector? A connector aka jack for the earphone, headphone, microphone, like any other gadgets has an equally interesting chapter in the book s of engineering. It is among the cheapest part but not the technically inferior. It deserves its attention from the engineers for its design and quality.The connector plays an important part of tranferring signals from the device like mobile, laptops, music players etc to the earphone and the microphone and vice versa. Even a small problem may lead to an unplesant experience with the device. The connector has three contacts/segments/parts called the TIP, RING, and the Sleeve. Therefore it is also called the TRS connector.

FPGA vs microcontrollers: Another approach to embedded design

Engineers Garage — Mon, 17 Jan 2022 14:06:52 +0000

Most engineers start their journey in embedded systems with microcontrollers. With microcontrollers, one gets a complete miniature computing system on a single integrated circuit. The CPU, RAM, ROM and Input / Output peripherals all on a single thumb size SoC. This very popular approach to learning embedded design and development is in fact just the one side of the complete picture. Working with microcontrollers (and microprocessors) is all about software-based embedded design.

How to determine whether a Person is sleeping through Brain waves (Part 7/13)

Arpit jain — Thu, 28 Oct 2021 15:52:04 +0000

Previously in the Brain waves applications, we worked on controlling the speed of the motor using the attention level of the brain. Now, it is time to check our study for some more real-time applications to detect if Brain wave can actually be used in day-to-day life or not. Presently in this article, I am planning to trigger something related to any type of Brain wave. In real life, often we may want to know if the patient (possibly our close one) is sleeping or not. So, I have tried to make a device using Brainwave through which I can find out if the person is sleeping with the help of a message/call.
