Line follower robot using 8051. Line follower robots were one of the earliest automatic guided robots. They are able to follow a line marked on a contrasting background, usually a black line on a white surface or a white line on a black surface.  Usually the line follower robot works on a closed loop feedback algorithm where the feedback from the line sensor is used by the controller for correcting the path of the robot. The sensors are usually LED/LDR, LED/Photodiode or LED/Phototransistor pairs and the controller is an electronic circuit which executes the desired feedback algorithm. Gear motors are…

Popularly called the “idiot box,” the television has become a vital part of our lives. Can you remember the days when there wasn’t a television set at your home? But, when and how was the television invented? Who was the brain behind this magnificent invention? Well, the history of invention of the television can be contributed to many great minds. In fact, it was not just a single idea that came to the fore, but a combination of inventions by pioneers. At the dawn of television history, there were two distinct paths of technology experimented with by researchers. Early inventors…

Without the application of barcodes, sales at stores would have been a very tedious process. The bar codes help a lot in effectively keeping an eye over the sold out items in a store. The brain behind the invention of barcodes should certainly be a ‘business’ mind. Well let us have a peep into the history of invention of barcodes. To start with, it is important to know what a barcode is. Barcodes represent the object to which it is attached. These are machine readable. The thickness or the width of the parallel lines and the distance between them makes…

The wonderful invention of the telephone is the result of work done by a number of individuals, the history of which involves a collection of claims and counterclaims. The ultimate development of the modern electrical telephone involved a range of lawsuits founded upon the patent claims of quite a few individuals and a lot of companies. The invention history of the modern telephone starts in the year 1844 from the conception of the idea of an electric voice transmission device to the failed attempts to employ “make and break” current, to successful research with electromagnetic telephones by Thomas Watson and…

No one can certainly imagine any electronic device without the presence of transistors. In that case, what was the idea behind the invention of transistors? Who were the people behind its invention and advancements? What was the real purpose behind the invention of field effect transistors? And how did it emerge? What are the current applications and advancements of these transistors? Have you ever wondered about these? If yes, then this write up will help you in knowing more about the interesting story behind the invention of the field effect transistors. Before entering into its invention part, let us have…

Mobile phone, the most common gadget in the present era, is considered as the greatest gift to the mankind. Can you ever imagine life without this device? No wonder the mobile phone has become an indispensable part of our lives. Of course, the origin of this gadget is as interesting as its use. Starting from bulky devices that were as long and heavy as one’s forearms to ultra thin and techno savvy handsets, the mobile phones have certainly covered a long way so far.  Well, any idea on who invented the mobile phone and how it was invented? To get…

When people go to a doctor for some pain or abnormality, the very first word the medical practitioner utters is ‘It is better to take an X-ray scan, because only then I can come to know the exact problem.” Well, have you ever wondered what X-rays are and who was the great mind behind this? Read further to have an elaborate view on the invention and inventors of the X-ray. Before getting to know about the history of invention, let us know what exactly X-ray is. X–RAY  X–Radiations are electromagnetic radiations with a wavelength of about 0.01 to 10 nanometers….

Without energy, would anything exist in the world? Living organisms like you and me and the flora and the fauna require some form of energy to survive. A bike, car, motor, television, everything requires some energy to start up, accelerate and even to stop. Thus, form of energy required for the survival or for the sustainability is termed as the fuel energy. The fuel may be any form of energy. Say for example, the food we consume may be either made of carbohydrates, proteins or even fats which can be converted to the storage form glycogen. Similarly, any form of…
