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?

Two new Arduino products are available starting today from the Arduino Store. Read below for details!
This shield allows you to connect devices to your Arduino using a USB port, for example game controllers, digital cameras, phones, keyboards, etc:
- it is based on the MAX3421E, which is a USB peripheral/host controller containing the digital logic and analog circuitry necessary to implement a full-speed USB peripheral or a full-/low-speed host compliant to USB specification rev 2.0.
If you want to see how to use it, take a look at this tutorial from Officine Arduino which used it to add wireless to an RC Car.
It’s a tiny AVR-ISP (in-system programmer) based on David Mellis’ project FabISP and useful to anyone needing more space on the Arduino board. Uploading a sketch with an external programmer can be used for three main reasons:
- remove the bootloader and use the extra space for your sketch
- burn the bootloader on your Arduino, so you can recover it if you accidentally corrupt the bootloader.
- when you use a new ATmega microcontroller in your Arduino, and you need the bootloader in order to upload a sketch in the usual way.

We recently featured Plotly and discovered how easy it is to analyse and beautifully visualize data using their platform and API.
Now they shared with us a simple instructable to show to Arduino Community a hands-on experiment with ambient sensors:
The purpose of this instructable is to demonstrate how to hook up an Arduino + Ethernet Shield and send data to Plot.ly’s Servers and create beautiful graphs. We will be using a dual temperature+humidity sensor (DHT22), and sending the results directly to Plotly. (more…)
Jonathan from Anikken wrote us to show how Andee is more than just a Bluetooth shield. Not only does it allow to wirelessly connect and control the Arduino from any Android phone, but it comes with its own library for the Arduino IDE, to easily customise the smartphone user interface by doing the coding in the Arduino IDE itself without any Android programming.
He then created some action with it producing a Rubber band launcher and a cool video to see how it works:
I got the inspiration to build this rubber band launcher after watching a video of a rubber band gattling gun. I originally intended to build a rubber band gattling gun turret that I can control with my smartphone using stuff that I could find in my home and office.
Unfortunately, I didn’t have enough materials lying around to get it done. Instead, using whatever I had, I improvised and made a simpler version – the Rubber Band Launcher Mark I. (I’m calling it Mark I because I’m in the process of upgrading this model).
Last August Arduino Tour landed in Singapore, hosted by The Hub Singapore. Davide Gomba held a workshop there and met a lot of cool people during the hackathon happening in the same days. Ted, one of the participants, submitted to our blog the Indoor Localization (see video below) project he prototyped with his team during the 24 hours CodeXtreme hours:
Our idea is to convert existing speakers inside shopping malls into an indoor localization beacon. This allows malls to track the location density without adding extensive infrastructure since it uses embedded inaudible sound signatures in music that shops play in the malls. In short, instead of tracking Joker, we use Arduino (with WiFI Shield & MP3 Shield) and Android to track people (customer) inside a mall.
With the growing popularity of smart phones in this time and era it’s interesting to explore how Arduino could tap on the strength of smart phones – touch screen capability and smart phone capability. However for the integration to work, one has to develop the corresponding Smart phone app to handle the bluetooth communication and provide a stable GUI on the screen.
Therefore to make things easier for Arduino developers who wish to tap on the power on smartphone, the Singapore-based team came up Annikken Andee project, an Arduino shield, with supporting resources, that performs primarily the following actions:
- handles the communication between Android and Arduino
- GUI creation on smartphone by coding on Arduino. Requires no Smartphone App programming
- accesses to Smartphone functions from Arduino Library
- provides larger, portable and non-volatile storage
The shield communicates with Arduino via the ICSP header (SPI) and pin 8. An SD card Reader is available for external data storage for Arduino – for huge data storage or extended period of data logging activity by Arduino. As Android has yet to support for Bluetooth 4.0/BLE, they are using bluetooth 2.1 module WT11i by Bluegiga for communicating with the Android phone. Currently the shield supports Arduino Uno, Mega and Leonardo.
Robin, part of the Team Annikken Ande, wrote us:
With Andee, Arduino user can program the UI on their Android phone by downloading the Andee Arduino Library onto their Arduino IDE and the Andee Android App into their Android phone from google play store. Using the functions in the Arduino library, user can easily design the UI on the Andee Android App without touching Android programming.
As we hope to spread the news of this invention to as many people as possible, we believe that arduino.cc is the perfect place to help us make this work.
The Lesser Kestrel (Falco naumanni) is a small falcon at the center of HORUS, a project aiming to develop a system for automatic real-time monitoring of colonial falcons at Doñana Biological Station, a public Research Institute in Spain.
The falcons breed in nest-boxes on the window sills which the research team converted into “smart nest-boxes”: they have sensors to identify the falcons entering the box using RFID tags, but also cameras and other equipment controlled by and Arduino Mega.

First and foremost, these include nuclear weapons, but they also encompass climate-changing technologies and new developments in the life sciences that could inflict irrevocable harm.
