Arduino & Raspberry Notepad Brancher votre prochain projet sur Internet avec cet adorable, abordable et mini microcontrôleur WiFi! Le processeur ESP8266 de la société Espressif est un microcontrôleur 80 MHz intégrant un support WiFi complet (aussi bien en mode client qu'en mode point d'accès) et une pile TCP/IP avec support DNS. Bien que l'ESP8266 soit vraiment populaire, ce composant est très difficile à utiliser. La plupart des modules bon marché ne sont pas compatible avec les breadboard, ne dispose pas de régulateur de tension (3.3V sous 500mA), ni de convertisseur de niveau logique et ne sont pas certifiés CE ou émetteur FCC....JUSQU'A MAINTENANT! L'Adafruit HUZZAH ESP8266 est un breakout conçu pour être super facile à utiliser et avec lequel vous prendrez beaucoup de plaisir. Plus d'information Voyez notre fiche produit sur l'Huzzah ESp8266 Où Acheter Vous pouvez acheter l'Huzzah ESP8266 chez MCHobby, il est disponible seul ou sous forme de Kit.

Simple electrical circuit with a single lamp or a motor: - Role of the generator; - connection wire; - Role of the switch. Drawing the diagram, standard symbols. Concept of the loop. Approach to the concept of a short circuit. Simple electrical circuit loop generator, switch, lamp, motor, LED, diode, connection wire, resistance (ohmic conductors), limiting itself, besides the switches to a generator and three components. Influence of the order and number of components other than the generator. Conductors and insulators. Conventional current. Series and parallel bulbs The electrical circuit comprising leads. Back to the short circuit: the distinction between short-circuit of a generator and short circuit of a lamp. Security. Current and voltage Introduction procedure of intensity and tension. Intensity : measurement, unit. Voltage : measurement, unit. Notion of branch and node. Additivity law verified for the voltage. Adaptation of a component in a given generation. Resistance
Arduino Les projets Sctratch et Scratch For Arduino sont développés par des Media Labs à des fins de transmission du savoir « programmer » pour les enfants, adolescents mais aussi les adultes qui découvrent l'univers de la programmation. Présentation de S4A et Scratch S4A (Scratch For Arduino) est une extension (modification) de l'application Scratch qui a été créée en 2007 à des fins pédagogiques : apprendre à programmer des histoires interactives, à concevoir et réaliser des projets, à travailler en équipe. Ces applications permettent donc au plus grand nombre d'appréhender l'univers informatique pour comprendre ces outils numériques qui font dorénavant partie intégrante de notre quotidien. Un détour vers Scratch va nous aider à découvrir S4A. Pour en savoir plus : L'extension S4A a été développée par Marina conde, Victor Casado, Joan Güell, Jose García et Jordi Delgado du Media Lab Citilab en Espagne aidé par le Smalltalk Programming Group. seaside.citilab.eu.

100 Top Resources for Electrical Engineers » Electrical Engineering Schools Electrical engineering is a highly technical pursuit that sits at the nexus of software and hardware development. Electrical engineers can design components and electronic systems for industrial machinery and consumer gadgets, and will often work in collaboration with manufacturers and designers to bring new electronic devices to market. There is also a huge hobbyist community of amateurs and professionals who advocate do-it-yourself electronics projects as a great way to learn about the inner workings of many of the household machines that people use every day. Electrical engineering can be quite technically challenging and requires a great deal of mathematics and physics knowledge, but the financial and personal rewards for succeeding in this field are great. Every piece of technology that runs on electricity, from the monster machines that clean the water for entire cities, to the ever-thinner cell phones in pockets today, required the expertise of an electrical engineer to make.
Pew Pew! How To Build A Laser Turret With An Arduino Are you bored? Might as well build a laser turret. You know – one that goes pew pew, shoots a red beam in lots of different directions, and maybe even throw in a smoke machine? What You Will Need Arduino2 servosLaser module, such as the one from this sensor kit (disclaimer: that’s my shop. Optionally, a smoke machine is needed – the laser is pretty low wattage, so you won’t be able to see the beam without smoke even in a dark room. Build Plan The basic idea of the turret is to put the laser module on top of one servo to provide horizontal rotation; then mount that package onto another servo placed at a 90 degree angle to provide vertical movement. Servo Testing Depending on your servo, the wires may be coloured differently, but in general: Once you’ve wired up your two servos, upload the following sample code. All good? Testing the Laser and Pew Pew Sound int laser = 12; pinMode(laser,OUTPUT); Then blink the pin on and off each loop using standard digitalWrite() method. Creating the Turret
