Tutoriels Arduino - Ethernet + SD Whatsit? We just got the latest version of the Arduino Ethernet shield with a MicroSD card slot and I promised Bill Greiman I'd try out the latest version of his SdFatLib library so I decided to code up a simple Webified file browser. Its a quicky project and demonstrates what you can do, but it isn't 100% perfect so you should be ready to modify it if you'd like to do other stuff, 'K? This is a good beginning to a logging web-monitor, or remote storage system. Get familiar Initializing Micro-SD card on an Ethernet shield The latest Arduino Ethernet shield comes with a handy MicroSD card slot so that you can store and retrieve data through the shield. Be sure to have the very latest version of SdFatLib , as you'll need some of the newer capabilities! First thing to note is that the SS (Slave Select) pin for the card is digital 4 (although as of the writing of this mini-tutorial, the schematic hasn't been updated, you'll have to trust me!) uint8_t r = card.init(SPI_HALF_SPEED); To: List files

ArduinoToBreadboard This tutorial explains how to migrate from an Arduino board to a standalone microcontroller on a breadboard. It's similar to this tutorial, but uses an Arduino board to program the ATmega on the breadboard. Unless you choose to use the minimal configuration described at the end of this tutorial, you'll need four components (besides the Arduino, ATmega328, and breadboard): a 16 MHz crystal, a 10k resistor, and two 18 to 22 picofarad (ceramic) capacitors. Uploading Using an Arduino Board Once your ATmega328p has the Arduino bootloader on it, you can upload programs to it using the USB-to-serial convertor (FTDI chip) on an Arduino board. Uploading sketches to an ATmega on a breadboard. Minimal Circuit (Eliminating the External Clock) If you don't have the extra 16 MHz crystal and 18-22 picofarad capacitors used in the above examples, you can configure the ATmega328 to use its internal 8 MHz RC oscillator as a clock source instead. Attention This procedure works on Arduino 1.0.x software.

LED Orb 2.0 : Une sphère POV RVB en rotation à base de LED Voici une réalisation électronique DIY très poussé, c’est un système de type gyroscope qui utilise plusieurs cadrans en rotation dotés de LED RGB. Ce montage dispose de 3 axes de rotation qui permette d’afficher une sphère électroluminescente à l’aide de la technique POV (Persistance of Vision) Ce qui m’a d’abord impressionné dans cette réalisation c’est le coté amateur de la chose, mais en regardant les détails, on s’aperçoit que le concepteur a dû bien ce prendre la tête avec certains détails comme l’équilibrage des pièces en rotation, ainsi que la transmission de données à l’aide de balai sur les différents axes. La structure est réalisé en bois, et les ensembles en rotation sont réalisé avec de petites tiges métalliques soudés à l’étain, plus artisanal que ça, on ne peut pas. La plupart des pièces ayant servit à la conception proviennent de récupération sur des vieux appareils électroniques HS, comme des magnétoscopes. Et voici le fonctionnement en vidéo : via :

PixelController « PIXELinvaders What? PixelController – a matrix control project by Michael Vogt , (c) 2010-2013. The main goal of this application is to create an easy to use matrix controller software which creates stunning visuals!I created this application to control the PixelInvaders panels. Download Download the latest PixelController version from Google Code (Crossplattform).

NRF24L01-2.4GHz-HowTo Having two or more Arduinos be able to communicate with each other wirelessly over a distance opens lots of possibilities:Remote sensors for temperature, pressure, alarms, much moreRobot control and monitoring from 50 feet to 2000 feet distancesRemote control and monitoring of nearby or neighborhood buildingsAutonomous vehicles of all kinds These are a series of 2.4 GHz Radio modules that are all based on the Nordic Semiconductor nRF24L01+ chip. (Details) The Nordic nRF24L01+ integrates a complete 2.4GHz RF transceiver, RF synthesizer, and baseband logic including the Enhanced ShockBurst™ hardware protocol accelerator supporting a high-speed SPI interface for the application controller. The low-power short-range (200 feet or so)Transceiver is available on a board with Arduino interface and built-in Antenna for less than $3! See it here. NOTE! Many users have had trouble getting the nRF24L01 modules to work. Range?? More Information on these pages: YD_nRF24L01_Receive_JoyStick
