As soon as we come across the word robot, we tend to imagine a metallic structure with arms and legs carrying a human-like appearance and running errands for our help. However, in actual terms, it’s just a machine operated externally or through a controller embedded within and doesn’t necessarily look like a human. Technically, robotics is a branch of Science and Engineering which deals with designing, constructing, and operating robots as well as computer systems for their control, sensory feedback, and information processing.Interestingly, the concept is almost as old as the hills with the first robot dating back to 350 BC, built in the form of a mechanical bird, by a Greek mathematician named Archytas. Although the term was coined ages ago, the actual potential of the fully autonomous robotics was realised in the second half of the 20th century.

Electrical projects are extraordinary in every sense, apart from specific subject knowledge one also needs proper workspace, motive, and tools to accomplish a job. For the regular domestic electrical projects, you can employ the most common tools that are present in every household. However, innovators, designers, thinkers, and engineers fall in a completely different category, they can’t work with regular common tools. They need specialty tools. We have aggregated here a list of top ten essentials that will help all creators in upgrading or completing their toolkit. Take a look.

As with any productive industry, the electronics sector is continually evolving and advancing.

I’m just conveying my emotions about robots to you. So people what is robotics?? You might be getting confused about the question itself.. Funny.. But in actual Robotics it is a wide field. Robotics is term denoted with respect to robots. WHAT is a ROBOT??Roughly we can say, ROBOT is a machine with brain and memory. Some bookish language may be elaborating it like “A reprogrammable, multifunctional manipulator designed to move material, parts, tools, or specialized devices through various programmed motions for the performance of a variety of tasks”. This definition is pretty expressive. 

A diode is the simplest electronic device. There are many different types of diodes. Most of are semiconductor diodes, while many diodes have a different construction from the typical PN junctions.

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 world of electronics is all about electrical circuits, electronic components, and interconnected technologies. All these elements can be primarily categorized as digital, analog, or a combination of both. However, here we will be focusing on the basics of the analog category in detail. Analog electronics is a branch of electronics that deals with a continuously variable signal. It’s widely used in radio and audio equipment along with other applications where signals are derived from analog sensors before being converted into digital signals for subsequent storage and processing. Although digital circuits are considered as a dominant part of today’s technological world, some of the most fundamental components in a digital system are actually analog in nature. 

A diode is the most basic semiconductor device. Yet, it has endless applications. In semiconductor electronics, the p-n junction as a basic diode serves as the foundation for all other sophisticated semiconductor components and their design. The design principles that apply to a semiconductor diode are the same applies to transistors and other components. Interestingly,…

 Some of you may be familiar with the terms FPGA or Field Programmable Gate Array. And familiarity does not necessarily beget understanding. So what exactly is FPGA?In simple terms it is a logic chip which contains a two dimensional array of logic cells and programmable switches. They are ICs that contain an array of identical logic blocks with programmable interconnections.Just as on a blank canvas you can paint any picture you want, FPGA allows an engineer to design any digital circuit. They say: just generate the bit file, download it and you’re good to go! This is a big development over the traditional microcontrollers as the architecture of such controllers does not support larger designs. For example, microcontrollers like 8051 used Harvard architecture with CISC instruction set. FPGA does not have any inbuilt instruction sets which provide the designer with much greater flexibility. A controller has its own CPU which starts the controller, retains memory and performs several tasks. Unlike microcontrollers, a FPGA will not be able to start functioning on itsown due to lack of the traditional architecture. 

There are some web-based simulation tools that aid the professional engineers and hobbyists in learning as well as carrying out various experiments related to the circuits.

Everyone who owns or wants to own a PC needs to know about motherboard. We all are always interested in Processor, memory-RAM, storage- Hard Disk. But we all tend to forget the most important component which ties all the above – Motherboard.Motherboard is glue which binds all the components of a Computer. Every component directly or indirectly attached/installed/connected to a system has a connection to motherboard, because it is the base on which system & its components/peripheral devices stand and perform. Technically speaking motherboard is a PCB- Printed Circuit Board that provides an interconnection to almost every component present in a PC. It is also known as system/main board. There are various roles that a motherboard plays. The important ones are: It acts as glue which binds all the components together. It’s main job is to coordinate with the various operations performed by the various components; it serves as a interface for all the modular singular components of a system like Central processing Unit – CPU, Random Access Memory – RAM, Storage device – Hard Disk ( Magnetic or Solid State); to provide slots and expansion cards to enhance the functionality of a system. There is development of new devices with new interfaces every day. Motherboard need to provide the slots to include the functionality; to deliver the power to the various components and devices as per their requirements. 

Today Torrent are the most common word used across whenever there is a talk about downloading a movie, TV program series or any big file like software etc. [[wysiwyg_imageupload:8324:]]A torrent file is nothing but a file that consists of the address and information about file of interest. So, what is torrent, how torrent became famous, how they increase the speed of downloading without affecting the bandwidth and how it is different from the traditional downloading?Now, it’s time to see how the software is fetching the data. The torrent file works on the method of peer to peer sharing downloading method i.e. file is downloaded in different pieces according to their availability. There are different terms that are being used by the torrent and you will come across such as seed, leeching, nodes, peers, swarm etc. To understand this downloading scheme, let’s go through the steps.  

Arduino is an open-source electronics prototyping platform based on flexible hardware and software, whereby the standard schematic can be used by anyone so as to make their own version of an Arduino board. An Arduino contains a physical programmable circuit board named microcontroller and software termed as IDE (Integrated Development Board). All the Arduino boards should be compatible with this IDE which is used to upload the computer code on the physical board.There are some very unique features contributing towards its exponential growth in the electronics world. It doesn’t need a separate piece of hardware to load the code on the board. Rather it can be done simply with a USB cable. Moreover, its IDE uses a simplified version of C++ which enables the beginners to get acquainted with programming in a convenient manner.
