In this tutorial you will learn how to communicate between the iPhone/iTouch app TouchOSC via a WiFi network to a Processing sketch displaying graphics and finally to control an Arduino board to light up an LED. TouchOSC is just one of many iPhone/iTouch apps that can send Open Sound Control signals. I particularly like TouchOSC because it's stable, it’s only $4.99 and most importantly comes with a really easy to use iPhone interface builder for your computer.

Arduino & Freeduino Knowledge
... an evolving index of practical subjects for the Arduino and Freeduino microcontrollers, as found in the Arduino site , Playground wiki, forum and that big WWW thing. Everything you read here will work on Arduino , the many versions of Freeduino , the Barebones and RBBB , the Boarduino , the iDuino and MAXserial , the eauDuino , the Jeenode , the many Arduino-compatible boards listed below, and of course the new-kids-on-the-block, the Sanguino , the Freeduino EPIC and the Arduino MEGA . Because of the different hardware layouts of these boards, slight modifications will occasionally be required between physical platforms.Breadboard Sanguino
Okay, so you want a Sanguino but Zach's Sanguino is too expensive ;-> Or too red ;-> Or you just have to have it NOW ;-> And you just used up the last of your solder so a strip board is out. What are you to do … bread board Sanguino. Of course, nothing in life is free.
Adafruit now has FREE SHIPPING – UPS ground, for all orders over $250. Continental USA. On checkout you’ll see FREE SHIPPING on check out if your order is $250 or over. We’ve been shipping so many packages lately, UPS gave us great rates, so we can now offer this as a great perk & added savings for our customers in the continental USA. This is also an experiment for us, we’ll see what else and what more we can do down the road – for USA customers,...

April 3rd, 2012 Check how the translation of the IDE is coming together. So far, after just 4 days in the making, we have 18 full translations and yet another 7 in the making. This prototype of the IDE boots in your local language. There is no way to select the language from a menu or similar, it just recognizes your preferred language in your computer and it boots that way. The demo shows how I change the language in my computer and reboot Arduino in some of the languages the system has been translated to already.

Drive a floppy motor
I wanted to quickly demonstrate using a stepper motor from a floppy drive with the Arduino/Wiring platform as a follow up to the weekend's workshop. By the time we got to the stepper parts I was a bit scattered. So here is an example that I set up yesterday.This tutorial demonstrates how to use the Arduino to read in the analog input and update a ThingSpeak Channel by sending an HTTP POST via the Arduino Ethernet Shield or the Arduino Ethernet (all-in-one). The analog input can be the output of a sensor, like a light sensor or temperature sensor. The Arduino + Ethernet Shield does not have DNS by default, so you need to send data using an IP address. ThingSpeak has an API address dedicated for its API. field1=(Field 1 Data)&field2=(Field 2 Data)&field3=(Field 3 Data)&field4=(Field 4 Data)&field5=(Field 5 Data)&field6=(Field 6 Data)&field7=(Field 7 Data)&field8=(Field 8 Data)&lat=(Latitude in Decimal Degrees)&long=(Longitude in Decimal Degrees)&elevation=(Elevation in meters)&status=(140 Character Message)

Another post on Pachube and how easy it is to get setup and going. This post will cover the basic steps on how to get some sensors online! I will be using my project of two light sensors as an example. The status of my light sensors are viewable at http://www.pachube.com/feeds/2145 Head over to the Pachube website and see various sensors from all over the world and view their status. Be sure to view the ABOUT page, this describes INPUTs and OUTPUTs, along with ways to interface with Pachube and your sensors.
