Théorie - Relais. Electronique > Théorie > Relais Dernière mise à jour : 06/07/2014 Présentation Un relais est un appareil dans lequel un phénomène électrique (courant ou tension) contrôle la commutation On / Off d'un élement mécanique (on se trouve alors en présence d'une relais électromécanique) ou d'un élement électronique (on a alors affaire à un relais statique).
C'est en quelque sorte un interrupteur que l'on peut actionner à distance, et où la fonction de coupure est dissociée de la fonction de commande. La tension et le courant de commande (partie "Commande"), ainsi que le pouvoir de commutation (partie "Puissance") dépendent du relais, il faut choisir ces paramètres en fonction de l'application désirée.

In 1999, when I started teaching in the Department of Sound at The School of the Art Institute of Chicago, I discovered that my students had adopted the computer as an almost universal tool. They were adept at using their laptops to edit a video, compose a dance track, retouch a photo, lay out a poster, write a term paper, and design a Web site.
Using the keyboard's command X and command V, they could cut and paste anything. But what the computer offered in the way of power and universality was obtained at the expense of touch. These were artists, after all, and even the filmmakers and webmasters started out scribbling on paper. Many of them complained about the lack of immediacy and tactility in digital media, and in 2002 I designed a course to show my students some electronic alternatives to the computer -- ways to bridge the gap between the sound world of a generation raised in an electronic culture and the gestural tradition of the hand.

Processing is an open source language/ development tool for writing programs in other computers.
Useful when you want those other computers to "talk" with an Arduino, for instance to display or save some data collected by the Arduino. Simple Examples Arduino comes with some basic examples for communicating with Processing (in Examples > Communication). CadSoft Online: Home of the EAGLE Layout Editor. BeagleBoard.org - default. Welcome. Firmata. Reference Language | Libraries | Comparison | Changes Firmata - Library - Baud Rate Details - Protocol Details - Protocol Proposals The Firmata library implements the Firmata protocol for communicating with software on the host computer.
This allows you to write custom firmware without having to create your own protocol and objects for the programming environment that you are using. Methods begin() start the library begin(long) start the library and override the default baud rate printVersion() send the protocol version to the host computer blinkVersion() blink the protocol version on pin 13 printFirmwareVersion() send the firmware name and version to the host computer.

Reference Language | Libraries | Comparison | Changes Description Re-maps a number from one range to another.
That is, a value of fromLow would get mapped to toLow, a value of fromHigh to toHigh, values in-between to values in-between, etc. Does not constrain values to within the range, because out-of-range values are sometimes intended and useful. The constrain() function may be used either before or after this function, if limits to the ranges are desired. Note that the "lower bounds" of either range may be larger or smaller than the "upper bounds" so the map() function may be used to reverse a range of numbers, for example y = map(x, 1, 50, 50, 1); The function also handles negative numbers well, so that this example y = map(x, 1, 50, 50, -100); is also valid and works well. The map() function uses integer math so will not generate fractions, when the math might indicate that it should do so. Parameters. Universal binaries. Un article de Wikipédia, l'encyclopédie libre.

The answer is easy to compute: divide 11 by 3 and take the remainder: 2. But how would you compute this in a programming language like C or C++? It's not hard to come up with a formula, but the language provides a built-in mechanism, the modulus operator ('%'), that computes the remainder that results from performing integer division. The modulus operator is useful in a variety of circumstances. It is commonly used to take a randomly generated number and reduce that number to a random number on a smaller range, and it can also quickly tell you if one number is a factor of another. Xcode.
