Robots are automatic electro-mechanical devices that are controlled by an electronic circuitry and computer program. Electronic circuitry includes major electronics and electrical components such as resistor, inductor, transistors, etc. There are different types of robots that are classified based on their applications. Recent trends in robotic technology have been developing many advanced robots such as microbots, nanobots, surgical robots, rovers, autonomous robots, industrial robots, space robots, modular reconfigurable robots or self-reconfigurable modular robots, and so on. These robots are used in several robotics applications. As a special case we discuss about a few most popular industrial robot applications in this article. [Read more…]
There are different types of comparators such as electrical comparators, electronic comparators, mechanical comparators, optical comparators, sigma comparators, pneumatic comparators, and digital comparators, etc., which are used for different types of applications. Consider the comparators that are used in designing electrical and electronics projects circuits. The op amp comparator circuit is frequently used in many applications. In this article, we will discuss about how to use an op amp as a comparator. But, primarily we must know what is a comparator. [Read more…]
An embedded system is an electronic system that has a software and is embedded in computer hardware. It is programmable or non- programmable depending on the application. An Embedded system is defined as a way of working, organizing, performing single or multiple tasks according to a set of rules.In an embedded system, all the units assemble and work together according to the program. Examples of embedded systems include numerous products such as microwave ovens, washing machine, printers, automobiles, cameras, etc. These systems use microprocessors, microcontrollers as well as processors like DSPs. This article gives an overview of what is an embedded system and types of embedded system. [Read more…]
There are many low-cost options to keep your energy bill low and to make homes, even industries as energy-efficient. One of the major option is to go for most abundant solar energy source to power up homes and industries. Over the past few years usage of solar power utilization is increased significantly and is expected to grow rapidly in the coming years. As cleanest and more sustainable energy, solar energy system is familiar with a wide variety of applications like solar power plants, spacecraft, home appliances, handheld calculator and so on.
As a common part of all the electronic power supplies circuits, rectifier circuit provides DC power supply from available AC supply for proper function of electronic equipments. Depends on the type of application, this rectifier configuration and types are varied like diode rectifiers and phase controlled rectifiers, etc. but each one has their own advantages and disadvantages. The rectifier circuit can be implemented with different solid state electronic or electrical components like diodes, SCRs, MOSFETs and so on. Upon these components used rectifier operation is varied in order to get the required output. Before going to know its types let us know what is a rectifier in brief. [Read more…]
As a rapid prototyping tool in various measurement and control engineering applications, LabVIEW allows to implement a wide variety of real-world relevant laboratory experiments. Latest projects and experiments in engineering applications are used to simulate the actual job conditions which are bound to a specific hardware and circuit components. In spite of this, we can create the virtual prototype models of real-time systems by incorporating LabVIEW programming language to engineering projects and experiments. Even though we can create and control various projects using LabVIEW with dedicated data acquisition (DAQ) hardware, more economically and to reduce the feasible time constraints, virtual laboratories and projects are introduced.

In these days, the major concern for many people is about the amount of electricity consumed in homes, offices, industries, and so on. Energy meter is an electricity measuring device, which records electrical energy consumption over a specified period of time. Thus, the accurate measurement and record of electrical energy consumption has greatly impacted the usage of energy meters. [Read more…]
A Computer is an electronic machine which is being used for many applications. The computer major parts are input devices, CPU and display monitor. There are various input devices such as mouse, keyboard, scanner, webcam and so on. But, the computer mouse is considered as a major input device which is used frequently while working with computer or laptop. Mice are classified based on different criteria. A few types of currently available mice are a PS/2 connector mouse, USB mouse, Wireless tilt wheel mouse, 3D mouse, Mechanical mouse and so on. As a special case we discuss about the wireless tilt wheel mouse in this article.
In general, while walking or running we can observe the inward roll of the foot, which is called as pronation or eversion and it is measured in terms of the degree of inward roll. But, we can look at pronation even in other terms like when foot pushes off at the end of each step or at the end of the gait cycle. The pattern in which animals or human beings move their limbs during many manifestations such as running or walking or swimming etc. is called as gait. The pronation has to be measured to avoid the underpronation and overpronation, as these may lead to foot, knee, ankle and hip injuries. But, how to measure pronation? [Read more…]
In our day-to-day life we frequently got used to listen the news, music and other programs through FM radio station by tuning to our favorite bands with wireless transmission and reception of data. Edwin Armstrong developed super-regenerative circuits and super-heterodyne receiver, which made radio broadcasting successful. In 1933, a revolutionary change was made by Armstrong in the broadcasting business with FM radio. The entire system depends on the FM radio transmitter to transmit the data from the transmitter end to the receiver end. But, are you aware of working of these FM transmitter and receiver circuits?
