Les microcontrôleurs Arduino donnent à votre robot l’intelligence que vous souhaitez. À l’aide de différents types de capteurs, Arduino peut contrôler des moteurs, des actuateurs, des LCDs ou n’importe quelle composante robotique, pour modifier comportement de votre robot.

WiMAX is a wireless digital communications system, also known as IEEE 802.16, that is intended for wireless "metropolitan area networks". WiMAX can provide broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations, and 3 - 10 miles (5 - 15 km) for mobile stations. In contrast, the WiFi/802.11 wireless local area network standard is limited in most cases to only 100 - 300 feet (30 - 100m).

make thoses phone events visible somewhere else, on your wearable, in your living room, on your robot, in your office or where ever you want it to occur? Or would you like to use your smartphone sensors, like the accelerometer, light sensor, compass or your touchscreen to control other devices? 'android meets arduino' is a toolkit, basically consisting of an Android application and an Arduino library which will help you to interface with your phone in a new dimension. You can build your own interfaces almost without any programming experience.

Qu'est-ce que PHP? PHP est un langage interprété (un langage de script) exécuté du côté serveur (comme les scripts CGI, ASP, ...) et non du côté client (un script écrit en Javascript ou une applet Java s'exécute sur votre ordinateur...). La syntaxe du langage provient de celles du langage C, du Perl et de Java. Ses principaux atouts sont : Une grande communauté de développeurs partageant des centaines de milliers d'exemples de script PHP ; La gratuité et la disponibilité du code source (PHP est distribué sous licence GNU GPL) ; La simplicité d'écriture de scripts ; La possibilité d'inclure le script PHP au sein d'une page HTML (contrairement aux scripts CGi, pour lesquels il faut écrire des lignes de code pour afficher chaque ligne en langage HTML) ; La simplicité d'interfaçage avec des bases de données (de nombreux SGBD sont supportés, mais le plus utilisé avec ce langage est MySQL, un SGBD gratuit disponible sur de nombreuses plateformes : Unix, Linux, Windows, MacOs X, Solaris, etc...) ; L'intégration au sein de nombreux serveurs web (Apache, Microsoft IIS, etc.).

Origines de PHP Le langage PHP a été mis au point au début d'automne 1994 par Rasmus Lerdorf. Ce langage de script lui permettait de conserver la trace des utilisateurs venant consulter son CV sur son site, grâce à l'accès à une base de données par l'intermédiaire de requêtes SQL. Ainsi, étant donné que de nombreux internautes lui demandèrent ce programme, Rasmus Lerdorf mit en ligne en 1995 la première version de ce programme qu'il baptisa Personal Sommaire Page Tools, puis Personal Home Page v1.0

A HTML DOM parser written in PHP5+ let you manipulate HTML in a very easy way! Require PHP 5+. Supports invalid HTML. Find tags on an HTML page with selectors just like jQuery. Extract contents from HTML in a single line.

// Create DOM from string $html = str_get_html('<div id="hello">Hello</div><div id="world">World</div>'); $html->find('div', 1)->class = 'bar'; $html->find('div[id=hello]', 0)->innertext = 'foo'; echo $html; // Output: <div id="hello">foo</div><div id="world" class="bar">World</div>

What is Arduino?

Arduino is a tool for making computers that can sense and control more of the physical world than your desktop computer. It's an open-source physical computing platform based on a simple microcontroller board, and a development environment for writing software for the board.

Inexpensive - Arduino boards are relatively inexpensive compared to other microcontroller platforms. The least expensive version of the Arduino module can be assembled by hand, and even the pre-assembled Arduino modules cost less than $50

Mini-bots

map out building interiors

The rolling droids are being developed by Georgia Institute of Technology, the University of Pennsylvania, and the California Institute of Technology/Jet Propulsion Laboratory (JPL). Equipped with two cameras and laser scanners, they can autonomously explore hallways in an unfamiliar building, detecting doors and windows, and create a map for users such as soldiers or firefighters. The project is part of the Micro Autonomous Systems and Technology (MAST) program and is being sponsored by the Army Research Laboratory. The program is aimed at developing palm-size machines that can hover in place, enter buildings, and perform other insect-like stunts while gathering data and relaying it to human controllers.

The conversion of sunlight into electricity has been dominated by photovoltaic and solar thermal power generation. Photovoltaic cells are deployed widely, mostly as flat panels, whereas solar thermal electricity generation relying on optical concentrators and mechanical heat engines is only seen in large-scale power plants. Here we demonstrate a promising flat-panel solar thermal to electric power conversion technology based on the Seebeck effect and high thermal concentration, thus enabling wider applications. The developed solar thermoelectric generators (STEGs) achieved a peak efficiency of 4.6% under AM1.5G (1 kW m−2) conditions. The efficiency is 7–8 times higher than the previously reported best value for a flat-panel STEG, and is enabled by the use of high-performance nanostructured thermoelectric materials and spectrally-selective solar absorbers in an innovative design that exploits high thermal concentration in an evacuated environment.
