Olympia, WA, April 29, 2013, Olympia Circuits introduces the Arno Shield to expand their line of products for new Arduino users. The Arno Shield contains all the components necessary to learn Arduino programming when plugged into an Arduino compatible board without any messy wires. The original Arno Learning Kit was introduced last year and received a great response as an innovative approach to learning the basics of electronics and Arduino. The shield provides another way for new users to dive into the world of Arduino and breaks down barriers to learning about microcontrollers.
The Arno Shield will be available for purchase at olympiacircuits.com on May 2nd.
The Arno Shield shares the same features of the Arno, but in a familiar shield form factor. Bring your own Arduino compatible board, drop in the shield and start learning to write sketches.
The Arno Shield comes with the well regarded book “Learn Arduino with the Arno” which gives step-by-step instructions for more than forty projects. All the components for the projects are built into the Arno Shield, so no wiring is necessary, just plug and play. The Arno shield, like the original Arno, is fully compatible with the Arduino programming language and integrated development environment.
To allow for a wide range of learning projects, the shield includes the following devices:
- Four green LEDs
- One RGB LED
- One infrared LED
- Two momentary pushbutton switches for digital inputs
- One thumbwheel potentiometer to introduce analog measurements and controls
- One piezo element to create tones and measure vibrations
- One phototransistor to detect infrared and visible light
- An I2C digital temperature sensor to introduce between-device digital communication
Users of the Arno have enjoyed the ability to dive right in to programming without messing with wires and small parts. Like the original Arno, the Arno Shield and an Arduino compatible board make a good travel kit that wonʼt get you hung up in security.

A wireless mesh Arduino board with USB, LiPo battery charger, built in range testing and over-the-air programming… cheap enough to leave in your project!
Gregor @ inDevice.ca have developed a low cost wireless Arduino board. It is based on the ATMega128RFA1 and uses Atmel’s wireless mesh stack. It also has a built in V-USB port for the bootoader and serial terminal and is fully compatible with Arduino. Some other unique features weʼve added is built-in range testing and wireless programming. There is a new video up showing two wireless boards working together and accepting commands from a WiFi shield. Right now they have a page up on Indiegogo, check it out.

sigalabs.com have designed and build a great OBD2 Arduino Shield using STN110 IC :
The STN110 is a multiprotocol OBD to UART interpreter IC. It provides an easy means of accessing vehicle data, including diagnostic trouble codes, MIL status, VIN, Inspection and Maintenance (I/M) information, In-use Performance Tracking (IPT), and hundreds of real-time parameters.
It is compatible with famous ELM327 commands but introduce many new great features.

RFduino: A finger-tip sized, Arduino compatible, wireless enabled microcontroller, low cost enough to leave in all of your projects!
The RFduino runs Arduino code and can do everything an Arduino can, plus much more. Using the RFduino USB shield, simply plug the RFduino into a USB port of any computer and use the Arduino IDE to load your Arduino sketch, which automatically begins running on the RFduino.Then you can detach the RFduino USB shield and plug the RFduino directly into your project.

NXP has announced the LPC800-MAX – an mbed/Arduino development board based on the LPC812 – which will be released in April 2013. [via]
NXP is working with key partners to develop LPC800-MAX, a development board which combines mbed, LPCXpresso and Arduino connectivity, allowing users to choose and work with their favorite elements from each environment. The breakthrough interoperability of the LPC800-MAX development board is made possible thanks to the unique flexible switch matrix feature introduced in the LPC800 family of microcontrollers, which allows users to configure nearly any pin for any available function. Further, with the new mbed USB onboard interface, users can choose if they want to use cloud-based mbed tools for development, or if they would rather use an off-line tool chain, such as the LPCXpresso IDE, for development and debugging. The board will be available in April for a suggested retail price of € 16.00.

Lira – A Barebones, Low-Cost, Arduino Compatible Atmega328 Breakout Board – [via]
What I came up with is the Lira. It is, as you will see, little more than a breakout board for the ATmega328, but it provides all the bare necessities like voltage regulation, basic power conditioning and an FTDI programming interface. It’s the smallest, simplest, cheapest design I could come up with that still uses through-hole components for ease of construction.
Certainly, your Boarduino has more features, better power conditioning and all of that. But then the Lira is significantly smaller at 2.15×0.85″ (vs. 3.0×0.8″, per the Boarduino page). So perhaps it will find an audience among those in search of the smallest, most bare-bones microcontroller they can build themselves.

Ardusumo is a universal platform to build robots on wheels that can move around avoiding obstacles using infrared sensors and follow routes marked with dark lines on a white background.
We have created Ardusumo to bring young students to the world of robotics: if suitably programmed, Ardusumo allows robots to perform various autonomous movements, it integrates sensors and actuators of various types with wheels and electric motors.
The platform is Arduino based but consists of a single molded frame that is both mechanical and electronic circuit. It has also various possible assembly, thanks to the modularity and versatility of the connections.
The electronic circuit of the Ardusumo robot is very simple: the core is an Arduino UNO board, interfaced with four sensors – three in front and one on the back- and two Sharp infrared radar. The optical sensors are pointed down and used to follow tracks marked on the ground and recognize when the robot is crossing a delimited border.
