Veille sur le verouillage a distance

Son pure data arduino. Controlling a relay via an Arduino from an Android client with NFC. Over the past few weeks I’ve been working on a small project that allows me to control electrical relays from an Arduino over the network from Android and C clients.

Controlling a relay via an Arduino from an Android client with NFC

It’s been delayed slightly from finals, holidays and power outages thanks to snow storms, but below is a demo of the first complete version. Looking for the source code or instructions on how to set up your own? The whole project aims to be as simple as possible. As can be seen in the demo video above, the hardware setup consists of an Arduino Uno, Arduino ethernet shield, PowerSwitch Tail II relay, two wires connecting the relay to the Arduino, and power and ethernet for the Arduino.

The protocol for communicating with the server is extremely short. GET operation: Just send a “g” to the server and it responds with the state of pins 2-9 in the form “2-0;3-1;4-0;” etc. where the first number is the pin and the second number is whether the pin is on or off.SET operation: Turns a relay on/off.

Commençons en douceur par l’explication de ce à quoi sert un moteur et son fonctionnement.

Ce chapitre n’est pas un des plus simples car il va faire apparaître des notions de mécanique qui sont indispensables pour comprendre le mouvement. Il prend en général plusieurs heures de cours pour être bien expliqué. Nous allons donc vous faire ici uniquement une introduction à la mécanique du moteur. Cependant, cette introduction présente des notions très importantes pour bien comprendre la suite, ne la négligez donc pas !

Prenons un moteur électrique des plus basiques qui soient : Vous avez devant vos yeux un moteur électrique tel que l’on peut en trouver dans les engins de modélisme ou dans les voitures téléguidées. Why Google Choosing Arduino Matters and Is This the End of "Made for iPod" (TM)? This week is the yearly Google I/O at the Moscone Center in San Francisco.

Why Google Choosing Arduino Matters and Is This the End of "Made for iPod" (TM)?

It’s a meet and greet for lots of people and companies, a big dot-com over-the-top party, and most of all it’s geared towards “web, mobile, and enterprise developers building applications in the cloud with Google and open web technologies… Products and technologies to be featured at I/O include App Engine, Android, Google Web Toolkit, Google Chrome, HTML5, AJAX and Data APIs, Google TV, and more.” Maybe not so much Google TV or Google Wave this year :) but for open hardware and mobile folks, this was one of the most important weeks in history. In this week’s column, I’m going to talk about Google choosing the open source hardware platform (Arduino) for the “Android Open Accessory” kit, and why this matters. I’m also going to talk a little about how Google could make it better. If mobile companies want to see the phone market blossom with creativity, with accessories never imagined, this is how it can happen. DIY Voice Activated Home Automation.

Voice recognition is no longer in infancy – You’ve got Siri on the iPhone and Google Now on Android (plus other Android apps too).

DIY Voice Activated Home Automation

This project shows you how to use it to automate your home without spending big bucks. The core of this project is a VRBot speech recognition module. Next, the project creator used some low-cost wireless light switches (you could also use relays). The VRBot speech recognition module recognizes 32 custom voice commands. Once a command is recognized, a wireless switch is activated via a radio receiver. Voice command for Arduino and Raspberry Pi using SMS. A couple of weeks ago I went ahead and bought the Wolfson sound card for the raspberry pi.

I was hoping to integrate it into Cortex to improve the voice recognition setup I had. This turned out not to work so well. The card has two built in microphones, but I had to be really close to the board to get a good quality recording. And even after applying some noise removal, the service I was using for voice recognition wasn't getting what I was saying (at least not all the time). SMS to the rescue. Looking for alternatives, I went ahead and opened an account with nexmo.com.
