By Mitchell Page Mpag5967 [at] mail.usyd.edu.au Key Centre of Design Computing and Cognition, University of Sydney , Australia Normally you would use a serial USB cable connected from your computer to your Wiring board for receiving data sent from a computer running processing to your board. This tutorial demonstrates how to execute this same process, but wirelessly using Bluetooth. We will test this by being able to turn an LED on/off wirelessly.
Bluetooth
I needed some ultrasonic range finders for my project. But most of the commercial sensors like Parallax’s PING sensor and other similar products are quite expensive, especially if multiple units are needed. So I thought why not building it myself?

To establish a , you have three possibilities: XBee All of them have advantages and disadvantages. Finally, when I had to choose, I decided to go for the Bluetooth solution which, in the given circumstances, fulfilled all my requirements. Once I had choosen the wireless technology, I still had to find a shield to interface the emitter with my Arduino Uno.
Arduino With Bluetooth, Wireless Communication Made Easy
Arduino Modules-Mozilla Firefox
La carte Arduino dispose de 14 entrées/sorties digitales et de 6 entrées analogiques, dont deux peuvent être utilisées en bus série Inter-IC ou encore appelé I2C. Bien souvent les aplications nécessitent plus d'entrées ou de sorties. Nous avons à notre disposition des circuits intégrés permettant d'étendre le nombre de ces entrées/sorties. Plusieurs articles sont disponibles en anglais sur le site Arduino, qui décrivent très bien les montages à réaliser afin de créer des modules d'extension entrées sorties.
arduino-tvout - A composite video output library for AVR/Arduino - Google Project Hosting-Mozilla Firefox
The goal of this project is to create a simple interupt driven library for generating composite video on a single AVR chip. Currently the output is NTSC or PAL at a resolution of 128x96 by default. The library currently works on ATmega168,328,1280,2560,644p,1284p,AT90USB1286 and more can be added by editing one file.
