Generally we know about interfacing button switches, LED with Atmega32 microcontroller. We know that interface switch’s to one port, LED’s to another port and if we press any switch the corresponding LED will glow. But all the LED’s operate with single switch we don’t know. Here we are developing the program for operating 7 LED’s […]

Touch screens are two dimensional input devices. Nowadays most of the electronic gadgets use them. Laptops, smart phones, tablets and even some home appliances like washing machines & microwave ovens also use a touch screen nowadays. Why Touch screens? Touch screens are preferred over keypads because they need very little or no pressure to operate […]

Researchers at the Department of Energy’s Oak Ridge National Laboratory and partners Lawrence Livermore National Laboratory and Wisconsin-based Eck Industries have developed aluminum alloys that are both easier to work with and more heat tolerant than existing products.

What is a GSM Modem? GSM stands for Global System for Mobile Communications.It is a standard set developed by the EuropeanTelecommunications Standards Institute (ETSI) to describe protocols for second generation (2G) digital cellular networks used by mobilephones. A Modem is a device which modulates and demodulates signals as required to meet the communication requirements.It modulates […]

(Phys.org)—In order to determine how fast quantum technologies can ultimately operate, physicists have established the concept of “quantum speed limits.” Quantum speed limits impose limitations on how fast a quantum system can transition from one state to another, so that such a transition requires a minimum amount of time (typically on the order of nanoseconds). This means, for example, that a future quantum computer will not be able to perform computations faster than a certain time determined by these limits.

Today, the National Science Foundation (NSF) announced a $30 million award to the Texas Advanced Computing Center (TACC) at The University of Texas at Austin (UT Austin) to acquire and deploy a new large scale supercomputing system, Stampede 2, as a strategic national resource to provide high-performance computing (HPC) capabilities for thousands of researchers across the U.S.

In a new study, published in Science, researchers from Uppsala University found that larval fish exposed to microplastic particles during development displayed changed behaviors and stunted growth which lead to greatly increased mortality rates. The researchers discovered that larval perch that had access to microplastic particles only ate plastic and ignored their natural food source of free-swimming zooplankton.

The growth of long facial feathers, creating the appearance of muffs and beards on chickens, is caused by a chromosomal rearrangement affecting a gene involved in feather development, report Xiaoxiang Hu of the China Agricultural University in Beijing and colleagues, in a new study published on June 2 in PLOS Genetics.

AVR microcontrollers are the advanced microcontrollers. From 1996 onwards these are come into existence. In AVR family there are so many controllers are available. Mainly the AVR family is sub grouped as ATmega, ATtiny, Xmega, UC3, SAM3 and SAM4. In these form 8 to 32 bit controllers are available. All the controllers having some common […]

Sally Fields’s famous Academy Award outburst of gratitude – “You like me, you really like me” – apparently holds true for customers who are asked to participate in retailer-sponsored Web panels, according to an article forthcoming in the June 2016 issue of the Journal of Retailing. One result of these panels, which are growing in popularity, is that participants feel valued by being invited to take part and tend to express their gratitude by buying more and across more different product categories.
