Wired Italy’s Video Profile of Arduino Co-Creator Massimo Banzi
Have a look at this wonderfully handcrafted 20-min webumentary about Arduino, made by Opificio Ciclope and produced by Wired Italia.
Nice format and nice look: good job.
The core of our story is the life of Massimo Banzi, and the region in which he was born: the Canavese area. In particular, the city of Ivrea, a veritable Mecca of Italian informatics, where Olivetti had its headquarters. The more we discovered their world, the more it became clear that this story was not only about silicon and circuits: it was about their shared excitement and their curiosity, like kids playing with their favorite toy.
(BTW, Massimo is not from Ivrea, but I guess Ivrea’s Mayor is going to give him and the Arduino Team the honorary citizenship)

Hello everyone,
I recently recieved some HC-SR04's and am wanting to make a little device to test them. The idea is that one sensor controls when a piezo buzzer will play, and the other sensor will decide the pitch of that note. I have written some code together but on trying to compile I get this error:
core.a(Tone.cpp.o): In function `__vector_7':
C:\Program Files (x86)\arduino-1.0.1\hardware\arduino\cores\arduino/Tone.cpp:523: multiple definition of `__vector_7'
I tried to write a code but the servo would not stay so
Please can someone write a c++ code for arduio for me
Hello,
I want to build a mini hexapod and i would like a suggestion from you for a cheap servomachine (de kserw an to grafw kala auto) to use, which will be sufficient for this project.. I have found these here on my own:
HobbyKing HK15148
HobbyKing 928BB

If you have a project that uses a bunch of Arduinos, how can you get them to communicate together? Scott Lawrence from The Geodesic Sphere shows us how to daisy chain multiple Arduinos together via their serial ports. He used this technique for his long-term Animatronic Avian project inspired by [...]

[Jason] and his father took advantage of a week off of work over Thanksgiving to design and build a Christmas light decoration that can flash fancy patterns. He calls it the Uno Christmas Tree. It’s sixteen strands of lights draped between a pole and the ground to form the shape of a tree. The main controller is an Arduino UNO, but what really makes this work is a mechanical relay board with sixteen channels.
Using trigonometry they figured out that the decoration would be fifteen feet tall and have a five-foot radius at the base. A pipe was installed to act as the trunk, with an old toilet flange at the top and stakes at the bottom to anchor the lights. They all make their connections at the controller box using extension cords that were labelled with channel numbers. You can see the final product in the video after the break. But you’ll also want to watch the clip on [Jason's] blog which shares the sonic symphony created when the mechanical relays really start working.
