Alongside such vending staples as candy bars and bottles of water, this machine dispenses USB cables, LCD displays, LEDs, breadboards and Arduinokits.

The machine also contains MREs (military “meals ready to eat”), an open-source breathalyzer kit, solder tubes, servos, DC motors and ShamWows, among other things.

[...]la riforma del secondo ciclo, con le nuove materie di Tecnologie Informatiche e Scienze e Tecnologie Applicate, reintroduce l’informatica già nel primo biennio di studi della scuola superiore. In questo contesto si aprono nuove opportunità e nuove sfide per migliorare l’insegnamento dell’informatica negli istituti tecnici e nei licei.[...]

The Android Open Accessory Development Kit (ADK) provides an implementation of an Android USB accessory that is based on the Arduino open source electronics prototyping platform, the accessory’s hardware design files, code that implements the accessory’s firmware, and the Android application that interacts with the accessory. The hardware design files and code are contained in the ADK package download.

The video is stop motion, so every frame is an individually shot photograph. Each photograph is a long exposure photo, with exposures reaching up to 20 seconds in some cases.

To control the lights, I used an Arduino controlled via bluetooth to drive a stepper motor. The stepper motor controls the movements of the lights remotely from Processing.

We made B-Squares for ourselves at first, since we’re guys who like to make things too.  While working on another project dealing with solar batteries in emerging markets this January, we put together a few crude prototypes of what would become B-Squares, thought it pretty amazing, and decided to push to pre-production ourselves.  Now we’re trying to complete the journey and make it a real product with our launch on Kickstarter. 

Assembling medium quantities of PCBs was never within the reach of a home based manufacturer. It requires expensive equipment, but most of these parts can actually be 3D printed, and you can use your existing 3D printer, such as the Ultimaker, to do pick-and-place operations.

RESTduino is a simple sketch to provide a REST-like interface to the Arduino via the Ethernet Shield. The idea is to allow developers familiar with interacting with REST services with a way to control physical devices using the Arduino (without having to write any Arduino code).

Of course some flexibility is traded for this convenience; only basic operations are currently supported:

• Digital pin I/O (HIGH, LOW and PWM)
• Analog pin input

Later versions of the sketch may provide additional functionality (servo control, etc.) however if you need more than just basic pin control you’re probably better off learning the basics of programming the Arduino and offloading some of your processing to the board itself.

serial2socket-proxy is a cross-platform software application developed in Processing for creating a virtual connection between the serial port and a network socket port.

For example, you can control an Arduino board connected to the serial port from any computer over internet. Also you can use this socket connection for communicate with your arduino board from Flash/Air application programmed in Actionscript, a PHP application or whatever language that can access to a socket

[...]the newest member of the RobOrchestra. This amazing musician was built by club members with a total budget of $1000. The Vibratron uses an Arduino Mega to control 30 individual solenoid gates which drop steel balls onto the vibration keys. Using the Arduino Mega they were able to avoid complications with multiplexing I/O lines. Notes are read in using a MIDI shield to receive standard MIDI signals from a sequencer or keyboard. The balls are recirculated using an Archimedes screw to raise them to the bucket at the top.
