WebServer
Web Server well structured For work I've done, I needed to put a webserver on an Arduino.Other examples are too easy for my case, so I realized this sketch.Now, I publish it for the Arduino community. Open source rocks! I hope someone can find it useful :-) mw - <Yes, I'm new to the Arduino and found your sketch a great starting point - thank you so much for posting. I have extended it to handle GET & POST, favicon and png images and a button to turn an LED on and off (on page3). Hardware needed an Arduino, obviously an Ethernet Shield Pages on flash memory There are 5 pages in this sketch (page 1, 2, 3, 4 and login). I've modified the script posted by Alessandro Calzavara to allow easy customization (removed variables limits and other stuff like URI managment). // Page 2 PROGMEM prog_char http_uri2[] = "/page2"; PROGMEM prog_char content_title2[] = "<h2>Page 2</h2>"; PROGMEM prog_char content_page2[] = "<hr /><h3>Content of Page 2</h3><p>Nothing here. Page request That's all. Sketch WebServer.h
Streaming Arduino Data to a Browser without Flash or Java | The Concord Consortium
What if you were reading a blog or working through an online lesson and you could just plug in your Arduino and start taking data or interacting with models right in your browser? Here at the Concord Consortium we are very interested in making sensors that are easy to use in the classroom or embedded directly into rich online curriculum. We’ve done some work in the past using applets as an intermediary to read data from commercial sensors and displaying them in lightweight graphs in the browser. When we think of fun, hackable, multi-probe sensors, though, we naturally think of Arduinos — we are open-source geeks after all. In thinking of ways to display Arduino data in a browser with the minimum amount of fuss, we considered both our existing applet technique and using the new HID capabilities of the Arduino Unos. With this idea, it was quick work to hack the Arduino Server example to send JSON values of the analog pins and create a webpage that would rapidly poll the Arduino for data.
O'Baka / One Chip Arduino
"0'baka Project" means a stupid project. This project is to make things which is not art and which is not usable. Now, I am making "One chip arduino" by using ordinary parts. Japanese English The circuit of LilyPad arduino is mounted on the DIP of ATmega88. LCD Digital Clock It used "One Chip Arduino", LCD and RTC. Arduino on Arduino I made DIP a flat by force to hold down height. It's form such as a weird bug. Connected LCD. "One Chip Arduino" which I made as a joke. other hacks (not o'baka project) Burning the Bootloader without external AVR-Writer Arduino meets Processing via Wifi

aJson – Handle JSON with Arduino — Interactive Matter Lab
Update: There has bee a major API change in Version 1.0 refer to the dedicated aJson page. Exchanging data with other computers can be a daunting task with Arduino. No matter if you just want to pass some information to Processing, to a Web Service or something else – You always have to encode the data and decode the answer. Using aJson To use aJson get it from the git repository or download the latest version. To parse the above structure with aJson you simply convert it to a object tree: aJsonObject* jsonObject = aJson.parse(json_string); (assuming you got the JSON string in the variable json_string – as a char*). aJsonObject* name = aJson.getObjectItem(root, "name"); The value of name can be retrieved via: Serial.println(name->value.valuestring); Note that the aJsonObject has a union ‘value’ which holds all possible value types as overlays – you can get only useful data for the type which you have at hand. name->type If you want to change the name, you can do so by Finished?

Push Notifications from Arduino to Windows Phone 8
This article explains how to push notifications from an Arduino board to an Windows Phone 8 application through the network. Introduction This is another post about integration between Arduino and Windows Phone. This article will explains how to send push notifications from Arduino to the Windows Phone through the network. It makes possible to alert you anywhere when some sensor state is updated. This post will show the following: How to connect to the Internet using an Arduino board; How to create push notification requests in Arduino; How to receive these push notifications on Windows Phone 8 application. Sample application (Simple alarm) An arduino board that listen to the infrared motion sensor and send a push notification to the mobile client application when some motion is detected. Architecture The below image shows how this architecture works togheter with the Arduino board. Mobile application Arduino (4) Receives the push notification and notify the user Hardware used Schematic Code
Das eigene Haus hacken: So baust du dir eine Fernbedienung, die Türen öffnet
Wer per Fernbedienung den HTPC oder Beamer hoch und die Jalousien herunterfahren möchte, das Licht dimmen oder die Heizung einschalten möchte, der benötigt eine Heimautomation. Fertige Produkte gibt es in diesem Bereich reichlich: Von der billigsten Funksteckdose (die nur bei gutem Wetter funktioniert) bis zur luxuriösen Produktserie, die die Tür abschließt oder die Heizung steuert. Wer viel Geld ausgeben möchte, kann die Installation getrost einem Fachmann überlassen. Wer aber Geld sparen möchte und den Drang verspürt, selbst Hand anzulegen, dem bieten sich vielfältige Möglichkeiten. Bis vor kurzem galten Mikrocontroller selbst unter vielen Programmierern als biestige Ungetüme. Was ist Arduino? Die Arduino-Plattform ist eine preiswerte Open-Source-Umgebung für ATMega-Mikrocontroller, die aus verschiedenen ATMega-basierten Experimentier-Platinen besteht. Welches Arduino passt für die Heimautomation? Funk mit RFM12 Die Zentrale und ihre Frontends Weiter auf Seite 2: „Die Steuerung per Web“ »
