"Arduino Uno" SMD Revision 3

TypeSingle-board microcontrollerWebsitewww.arduino.cc

Arduino is an open-source computer hardware and software company, project and user community that designs and manufactures microcontroller-based kits for building digital devices and interactive objects that can sense and control objects in the physical world.^[1]

The project is based on microcontroller board designs, manufactured by several vendors, using various microcontrollers. These systems provide sets of digital and analog I/Opins that can be interfaced to various expansion boards ("shields") and other circuits. The boards feature serial communications interfaces, including USB on some models, for loading programs from personal computers. For programming the microcontrollers, the Arduino platform provides an integrated development environment (IDE) based on the Processingproject, which includes support for C, C++ andJava programming languages.

The first Arduino was introduced in 2005, aiming to provide an inexpensive and easy way for novices and professionals to create devices that interact with their environment using sensors and actuators. Common examples of such devices intended for beginner hobbyists include simple robots,thermostats, and motion detectors.

Arduino boards are available commercially in preassembled form, or as do-it-yourself kits. The hardware design specifications are openly available, allowing the Arduino boards to be manufactured by anyone. Adafruit Industries estimated in mid-2011 that over 300,000 official Arduinos had been commercially produced,^[2] and in 2013 that 700,000 official boards were in users' hands

New Project Ideas

New Project Ideas

GSM Based Tracking system for parents to monitor students attendance in Colleges , this electronic projects is for Electronics and Communication Engineering ( ECE ) students as well as EI .

Abstract :

It is time consuming task for the parents to check regular presence of the student to the college. And also for the college administrative people it is time consuming task to check each and every student attendance and marks to inform to the parents.

But this project An Intimation to the parents about the bunking of the student for the college through GSM SMS will give and easy, low cost and automatic solution .

In this project we are going to use ARM7 based LPC2148 Microcontroller. The transmitting section consists of RFID module and GSM modem receiving section is the GSM based mobile phone.

SOFTWARE: Embedded ‘C’
TOOLS: Keil, Flash magic
TARGET DEVICE: LPC2148(ARM7) Microcontroller.
APPLICATIONS: Schools and Colleges,
ADVANTAGES: Low cost, automated, reduce the burden for parents to know students attendance.

Liquid Robotics, the maker of Wave Glider autonomous ocean-faring robots, Tuesday announced the winner of its inaugural PacX Challenge.

The startup, which launched in 2011, awarded $300,000 worth of research time on a Wave Glider, as well as a $50,000 research grant from BP to Tracy Villareal, a professor of marine science at the University of Texas at Austin.

Villareal's propsoal, which beat out four other finalists, focuses on comparing scientific spatial data gathered by US satellite streams to data collected on the surface of the ocean using a Wave Glider. The goal is to understand the detection and behavior of phytoplankton species thought to be both essential in pulling carbon from the surface of the ocean and a major source of food for deep-sea species.

In a release, Liquid Robotics said that Villareal's research gave the scientific community valuable new validation from the ocean's surface of what had previously been seen only by satellites. That data is essential in understanding how global climate change is affecting the health of the oceans.

Precise drug delivery through nanoscale engineering

Pharmaceuticals that can be precisely delivered at the molecular level within or around a diseased cell offer unprecedented opportunities for more effective treatments while reducing unwanted side effects. Targeted nanoparticles that adhere to diseased tissue allow for the micro-scale delivery of potent therapeutic compounds while minimizing their impact on healthy tissue, and are now advancing in medical trials. After almost a decade of research, these new approaches are finally showing signs of clinical utility.

 

MOSFET

 The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a transistor used for amplifying or switching electronic signals.In enhancement mode MOSFETs, a voltage drop across the oxide induces a conducting channel between the source and drain contacts via the field effect. The term "enhancement mode" refers to the increase of conductivity with increase in oxide field that adds carriers to the channel, also referred to as the inversion layer. The channel can contain electrons (called an nMOSFET or nMOS), or holes (called a pMOSFET or pMOS), opposite in type to the substrate, so nMOS is made with a p-type substrate, and pMOS with an n-type substrate (see article on semiconductor devices). In the less common depletion mode MOSFET, detailed later on, the channel consists of carriers in a surface impurity layer of opposite type to the substrate, and conductivity is decreased by application of a field that depletes carriers from this surface layer
