In the previous articles, we discussed passive electronic components like resistors, capacitors, inductors, and transformers. The passive components are particularly useful in designing various analog circuits. The real fun of modern electronics begins with semiconductors and digital electronics. Electronics is all about signals (in the form of voltage or current) and processing signals by components…

AT commands are used to control MODEMs. AT is the abbreviation for Attention. These commands come from Hayes commands that were used by the Hayes smart modems. The Hayes commands started with AT to indicate the attention from the MODEM. The dial up and wireless MODEMs (devices that involve machine to machine communication) need AT…

While AR, VR, IA, and IOT are sprinting hard to lead the tech world, there is one strong contender that will be an essential part of every journey – Robotics. Even now, it is slowly becoming the strongest channel for streamlined implementation of above mentioned technologies in our everyday lives. Taking another step ahead in this direction, we bring you a list of top ten noteworthy startups who have made their mark within a short time and are moving ahead with flying colors.

In this article, we will control our home geyser from anywhere in the world. Life is fast and busy, and we all want to leverage the benefits of technology in our day-to-day life by automating where and when we can. In this experiment, we will automate our geyser in integration with our alarm app so…

In this tutorial, we’ll learn how to build a device that works as a virtual doctor. The device inputs patient data, which can then be emailed remotely to a registered physician using the simple mail transfer protocol (SMTP) — the internet standard communication protocol for electronic transmissions. The purpose of this device is to support…

You may know how to drive or you are just like me who always tag along as side kick, but there is one part of automobile that is voluntary known to each one of us “Speedometer”. You may not be driving but one step on accelerator by the driver and you are squirming on your seat just as the needle on the meter. Ha!We have never really thought how does a needle move on the meter?  What makes the number change on odometer? We look at speedometer but never really notice it. But not anymore join me in this insight to learn all about speedometer. Let’s understand in depth all about it. 

In present times increasing Traffic is adding to the big woes of developing cities. The main roads are packed with vehicular traffic on each and every road or a traffic signal (Intersection Points). One comes across the common problem of traffic jams on almost all Traffic Junctions which is even critical if you go to big cities. A lot of time, energies besides precious fuel is wasted just because of these Traffic Jams on the roads.To solve this problem Traffic Cameras are used over Traffic Intersection points. Traffic Cameras capture the image of vehicles in traffic and sends to MATLAB. Here in this project Traffic Surveillance System is demonstrated by way of how the traffic could be controlled over traffic intersection points from the Traffic Control Room. This is a very effective system for Traffic Surveillance. 

The decorative Light Fountains are readily available in market as gift articles. Here the given project demonstrates how to operate it using TV remote (or any other remote of AC or Music System etc.)To make it Remote Operated it needs to be modified, inside its Internal Circuits and there is also a need to build one Simple Circuit using IR Sensor to sense IR Remote Signal. For your convenience kindly follow step by step process of how to do this with the help of given images. 

Video is basically data; rather we can term it more aptly as a signal. The signal can be transmitted as analog or digital signal/data; but the thing which remains in the background is that what makes this signal so special. Let us look at this that “how video is displayed on a screen”. First we…

Ultrasonic sensors have been a popular method for distance measurement and object detection for many years. Their basic operating principle works by measuring the amount of time it takes for their emitted ultrasonic pulse of sound to bounce off an object and return, hence the name ultrasonic sensor. With the market for autonomous robots, vehicles,…

The FPGA is one of the technologies which let an embedded engineer access hardware design of an embedded system. Its greatest advantages include multi-threading, real-time processing, wide scope for custom ASIC design (within available logic blocks on the FPGA chip), reusability and single chip solution. It is highly recommended to get hands dirty on an FPGA board after some work on microcontrollers. After all, hardware design is just another essential twin to software design in embedded engineering discipline.

Scratch is a programming tool for creating embedded games,stories and animations without using any written codings, rather using visually organized syntax which is in blocks with a drag-and-drop interface. One can use these blocks according to one’s requirement, scratch’s control of hardware is not only limited to the external inputs such as the keyboard and mouse.This article explains how to configure Scratch to extend its power to access GPIO(General Purpose Input and Output) of the Raspberry Pi.

This article is to make the procedure of setting up the WiFi. The Raspberry Pi is connected to Windows PC through Ethernet cable and the GUI is obtained using a VNC server. Although Raspberry Pi Model B comes with 100Mbps wired Ethernet, it is also essential to connect WiFi.The best arrangement is to purchase a cheap USB WiFi connector and utilize one of the USB ports to get to our WiFi home router. Setting up a Raspberry Pi utilizes the Raspbian OS to get to your remote system is simple – This article will guide you through the procedure.

Universal Serial Bus (USB) is now a common and vast framework for serial communication. The interface not only allows serial communication, it also works as electronic power supply. The popular AVR microcontrollers fortunately have the USB interface feature and can be programmed to build USB devices. The USB specification is long and intimidating. It can be a daunting task to write a device specific USB driver.

With the rapid use of smartphones and tablets around the globe, apps have become an inseparable part of our lives. Not only we tend to use them for entertainment but these are also quite useful for educational as well as professional purposes. This wide spectrum of users also includes people belonging to the field of electronics ranging from beginners to professionals.There are different apps which provide access to important information regarding the materials, tools, calculations and notable theoretical knowledge involved in the electronics projects. 

Measuring an individual battery voltage or a whole bank of battery using any microcontroller(arduino, microship pic, Avr, Atmega, Intel, NXP, stm32)is an easy task. You can find many tutorials on internet on how to do so. But what about if we want to measure an individual battery connected to a cluster of batteries in series…
