PROGMEM

There's a description of the various types of memory available on an Arduino board. The PROGMEM keyword is a variable modifier, it should be used only with the datatypes defined in pgmspace.h. It tells the compiler "put this information into flash memory", instead of into SRAM, where it would normally go. PROGMEM is part of the pgmspace.h library. #include <avr/pgmspace.h> Syntax dataType variableName[] PROGMEM = {dataInt0, dataInt1, dataInt3 program memory dataType - any program memory variable type (see below) variableName - the name for your array of data Note that because PROGMEM is a variable modifier, there is no hard and fast rule about where it should go, so the Arduino compiler accepts all of the definitions below, which are also synonymous. Using PROGMEM is also a two-step procedure. As mentioned above, it is important to use the datatypes outlined in pgmspace.h.

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. Ovidiu Predescu's Weblog: Arduino Tiny Web Server - part 3.

Webduino - Simple and extensible web server for Arduino and Ethernet Shield. This is an Arduino-based Web Server library, originally developed for a class at NYC Resistor.

webduino - Simple and extensible web server for Arduino and Ethernet Shield

It's called Webduino, and it's an extensible web server library for the Arduino using the Wiznet-based Ethernet shields. It's released under the MIT license allowing all sorts of reuse. I've also put my not-quite-complete presentation up for viewing at . I've got a few examples up right now -- the Buzz example interfaces with Zach's Danger Shield allowing you to remotely start and stop the speaker. We had a room full of students pinging my Arduino board on Saturday, buzzing me while I was lecturing. I hope to add a few more examples in the next few weeks, including a web-enabled fridge sign using a serial LCD and how to serve things other than just HTML text from the device.

Installation Notes. Arduino Control via a Web Service with Teleduino. Convert your Arduino into a sofisticated web control platform using Teleduino.

Arduino Control via a Web Service with Teleduino

Teleduino is both a product and a service. Once the Teleduino sketch has been loaded on your Arduino (the 'product'), it then connects to the Teleduino server awaiting your instruction from anywhere in the world via the internet (the 'service'). Typically there are no firewall changes required, and if your network supports DHCP then no network configuration is needed on the device. Easy! Make it Tweet.

Typically there are no firewall changes required, and if your network supports DHCP then no network configuration is needed on the device. Easy! The Teleduino platform allows you to perform the following with your Arduino, all via the internet: Reset, ping, get version, get uptime, get free memory. This tutorial will guide you through creating a Status LED for your device, then obtaining and uploading the Teleduino library/sketch to your ethernet enabled Arduino Uno (or equivalent).

Getting Data From The Web – Arduino + Ethernet. Yesterday we covered how you would go about controlling pins of your arduino over the internet using the Arduino Ethernet Shield set up as a server.

Getting Data From The Web – Arduino + Ethernet

Today we are going to take a look at using the shield as a client to get information off of a web page, and report back. I used this method a few months ago when I made the Nixie Twitter follower counter dubbed Twixie. The ethernet shield can be used to access any non-password protected site with ease, but getting the information back to you is the hard part. For Twixie I created a special php page that queried the twitter API and displayed only the twitter count. This made it so I didn’t have to tell the arduino what to look for, or scour endless lines of HTML looking for a single number. In the client mode, the ethernet shield is able to access a webpage and return what is read. Because of this, we need a way to tell the arduino what is junk, and what is the good stuff.

Cheap 2-Way Bluetooth Connection Between Arduino and PC. In the guide, I will explain how I managed to send data back and forth between a PC and Arduino via a cheap Bluetooth HC-05 transceiver, which can be found for less than $10 on ebay with the breakout board. The version I have used in this project does not have a breakout board so it's little cheaper but more difficult to solder. I strongly recommend buying the module with the breakout board. This Bluetooth transceiver basically acts as a generic serial COM port.

The PC to Arduino Bluetooth serial connection can be useful in many applications such as controlling servos, motors, and writing to LCDs. The Arduino to PC connection can be useful in applications where the Arduino reads sensors then pass their values via serial Bluetooth to a PC for processing. The only downside of this cheap Bluetooth transceiver is the absence of headers which means you have to solder at least 4 wires. The Bluetooth serial module I bought has the following specs: Arduino Tutorials - 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!)
