When The Norwegian Broadcasting (NRK) planned the television broadcast of the Chess Olympiad 2014 in Tromsø, Norway, they encountered a challenge: how to mix video, graphics and the results of many ongoing chess games simultaneously, requiring 16 cameras for the games going on at the same time?

The world’s most diverse showcase of creativity and innovation in technology, craft and science is starting tomorrow in San Mateo, California and the Arduino team will be there with more than a couple of new things to present.
First of all, finally and officially the Arduino Robot will be alive and running around the Arduino tent to bring you into the world of robotics. Designed with Complubot, the 4-time world champions in Robocup Junior robotics soccer, the robot allows for endless hours of experimentation and play. It is a self-contained platform allowing you to build interactive machines to explore the world. As all the other Arduino products you can use it as it is, modify its software and even add your own hardware on top of it: it is perfect for the novice but also for those looking for their next challenge.
As you may have read in the article published on MAKE some days ago, The Arduino Robot is the result of the collective effort from an international team looking at how science can be made fun to learn and we loved to share its story. Connected with this aim, David Cuartellies – head of Arduino Verkstad, the Arduino office in Malmö (Sweden) – during Maker Faire Bay Area will present the Castilla Education Project aiming at evaluating the use of Arduino and other open source tools in the schools of Spain. He’ll especially focus on the way content was created and validated in an experiment involving 24 schools, 30 teachers, over 500 kids, and a 6-members design team.
On the topic of education also Michael Shiloh — Coordinator of Education materials for Arduino, will be on the Education stage on Sunday at 4.30pm for a Q&A on how to use Arduino boards and how to prepare material for teaching.
Then we’re happy to announce that Arduino is releasing the new version of the Arduino IDE and the new TFT screen. TCT LCD library relies on the Adafruit GFX and ST7735 libraries. The Arduino specific library, named TFT, extends the Adafruit libraries to support more Processing-like methods. You can write text, draw shapes, and show bitmap images on the screen in a way that should be familiar to users of Processing.
If you want to hear all these news from the voice of Massimo Banzi, don’t miss the center stage of Maker Faire Bay Area, saturday 18th of May from 1.30 and come to visit us at the Arduino tent (see map below for directions).
They created a new shield to control Dinamyxel servomotors to work with PWM laser drivers. The shield works using Arduino Ethernet programmed with a specific firmware to control laser and motor using Open Sound Control.
The project involved a team of 3 people (Eloi Maduell, Alex Posada and Santi Vilanova) coming from the field of audiovisual creativity, hardware engineering and software development.
To show us the way this system can be used, they sent us two of their projects. Enjoy! (more…)
In this tutorial, Luca shows how to add WiFi connectivity to your Arduino boards without using a WiFi shield. Instead, he has combined a standard Ethernet shield with a commercial (and quite cheap) WiFi router:
I found the TL-WR702N nano router by TP-LINK that, with a cost of about 20€ on eBay, can work also as a wireless client: in this mode the router acts like a “bridge” between the device connected to its ethernet port and a Wi-fi network.
After a simple setup, where Luca configured the router as a WiFi client, the Arduino board has become accessible from the wireless network. Enjoy!

Rebuilt my lucky cat: whenever a page of my website is loaded, the cat will be waving its arm. There’s a light sensor so when its dark, the cats RGB-LED is changing the color instead of waving the arm. Changing the color of the LED is also possible with one of the buttons on the cats ears. The other one is the reset button. Used an arduino ethernet, a servo, two buttons, an RGB LED and two small yellow LEDs. The seven segment display is one that I harvested from an old stereo. It’s driven by the arduino and two shift registers. unfortunately I’ve soldered that one together for an older project, so that it doesn’t fit into the cat too. It shows the number of pageviews of the website.
What do you do when you have an arduino, a camera, an ethernet shield and a doorbell? You make your own intelligent security system.
The system is actually pretty simple. When the doorbell rings an Arduino sends a request to a notification service called PushingBox which then grabs a picture from web camera located outside. Then PushingBox sends a notification to an iPhone (it looks like this can be modded slightly with PushingBox to include Android and Windows Phone as well) and an email with a picture attached.
The next time you wish to take a random photoshoot with one of these phones, do make a note that they are Arduino powered! The makers Chris Bell, Liangjie Xia, and Mike Kelberman built the Rotobooth as part of Twilio’s Photohack Day 2 event designed to showcase Twilio’s cloud computing capabilities.
When users lift the handset and dial their digits, an Arduino (you just knew there’d be one involved didn’t you?) takes in the information and then initiates the camera.
Four photos are taken — just like a photo booth — and they are sent to a Mac Mini. The photos are resized, watermarked and uploaded to Flickr. The photo links are then texted to your phone using Twilio.
If you decide not to enter your number just dial “0″ and one photo is taken and is uploaded to Rotobooth.com
Now just dial your number on the Rotobooth’s rotary dial and once your photo is taken, the shot is uploaded to Flickr and you are texted with the link.
If you’re into interactive lighting you’ll be familiar with protocols like DMX and ArtNet.
VVVV user “karistouf” has written a piece of code for the Ethernet shield that allows your Arduino to communicate over an ArtNet network.
ArtNet receiver v2: fixed artnet length receiver.
ArtNet sender: you can send artnet data from your device over network, for sensors and buttons this will be easier than all osc or firmata solutions.
For those of you who are addicted to merge new technologies to interface-archeology here is a new ‘Tworsekey’. A vintage looking tweeting device which takes input in the form of morse code and tweets the output. It features arduino and the ethernet shield. The sketch can be downloaded from here. Needless to say that the design is open sourced.
In case you want to build it, the design details can be obtained from here.
