ArtNet library for Arduino

Thursday, March 8th, 2012

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.

Features are:

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.

Social Fuel For Your Car: Travel With A Little Help From Your Friends

Thursday, February 23rd, 2012

Impressing automotive hacking lets this FIAT car moving by the number of “like” from the Guarana Antarctica Facebook Fan Page. The advertising idea is simple: let the social audience support this Sau Paulo to Salvador trip to reach the Carnivalby commenting / “liking” the page. The onboard Arduino ADK (connected to a tablet and the internet) allows the car going on by a certain amount of meters (apparently one “like” is 10 meters, while each comment lets the car go ahead for 20 meters).

Control An LCD with a 595 Shift Register

Monday, January 16th, 2012

[Carlo Denaro] is sharing a smart solution to save digital pins while controlling an LCD, using Shift Register 74HC595. A simple yet useful project with skecth&libraries, datasheets and Fritzing schematics.

ITP Winter Show

Sunday, December 18th, 2011

For the past couple weeks I’ve been wrapped up in finals at ITP, and in producing the ITP winter show 2011, along with my colleague Marianne Petit. I lost count of all the great Arduino projects in the show, but probably somewhere around 70% of the 110 projects in the show have a little blue board somewhere inside. If you’re in New York City today or tomorrow, come on down, it’s a good time, with lots of creative projects covering a range of application areas from healthcare  to fashion to video sculpture to politics, data visualization, assistive technologies, and more.

 

 

Here are a few selected at random that are using Arduino:

  • FOLKBOX is a device that allows a person with limited left-hand dexterity to play the acoustic guitar, by Justin Lange.
  • Glute-o-licious is a virtual cycling experience in which the user controls the speed of a first-person video by riding a stationary bike, by Courtney Mitchell
  • HeartRacer is a portable exercise-based video game that plugs into your TV and is powered by your heartbeat, by Nick Santaniello
  • Kinetic Sculpture 5 is composed of five pendulums that the viewer can control. Simply wave your hand over the sensors to “play” the piece, by Ben Light
  • Metrochange is a charity donation platform using New York City subway cards, by Genevieve Hoffman, Paul May, and Stepan Boltalin
  • RFID Beat Box is an instrument that lets you create and play your own music using RFID tags, by Danne Woo and Stefanie Kleinman
  • Nostalgia is an interactive art piece where you can view a memory of the artist’s past by typing, by Yoonjo Choi
Here is a full list of the projects. Come and see them all!

Connecting your Arduino to AIR using an AIR Native Extension

Monday, December 5th, 2011

[quetwo] aka Nicholas Kwiatkowski developed a native interface to receive serial data in Flash.

[...]  The AIR Native Extension (ANE) is a C based .DLL / .framework for the Windows/Mac platforms that allows AIR to essentially open a COM port.  I wrote it in a way that is supposed to emulate the functions of the flash.net.Socket library that is included in the AIR runtime.  I’ve posted the entire project, including the source code and final binaries on Google Code at http://code.google.com/p/as3-arduino-connector/

Matatino Lets Arduino Connect To Your Mac Apps

Tuesday, November 8th, 2011

[Robotgrrl] shared a super-userful way to import Arduino Data to  Mac applications, with tutorials and examples.

We created Matatino, a framework that lets you communicate between your Mac applications and your Arduino, You can follow our tutorials to get started with adding Matatino to your project. To see Matatino in action, check out Meters for Arduino. We will be adding more examples, libraries and tutorials for the Android ADK, iOS Redpark Serial Cable, Processing and OpenFrameworks in the future! You can stay informed about updates through RobotGrrl’s blog Apps4Arduino category feed.

Ball of Dub Keeps Audio in Your Hands

Tuesday, November 1st, 2011

Ball of Dub from LUSTlab on Vimeo.

Accelerometer to Renoise via OSC  to control trippy and dubby sounds.

[Lizzie] from LustLab sent in her Ball of Dub that turns a few accelerometer and a digital audio workstation and turns everything into an aural experience of wubs and dubs. The Ball of Dub can turn just about anything into dubstep, and does so with a fairly interesting user interface.

There isn’t a build log for the Ball of Dub, but  the folks at LustLab did send in a basic overview of her project. Inside the ball, there’s a Razor IMU from Sparkfun that is attached to the ever-popular XBee wireless transceiver. A tiny program on an Arduino calibrates the gyroscope and accelerometer and sends that data to the DAW at 50Hz.

The host computer is running Renoise, a very popular tracker that can accept MIDI and OSC input. A Processing app parses the ball spin, free fall and impact, averages them over a period of time, and pipes that into the OSC input of Renoise. In [Lizzie]‘s video, the ball spin is sent to a low-pass filter on the baseline track, and the average impact is applied to the vocal track.

HC-SR04 ultrasonic Arduino library

Thursday, October 20th, 2011

This is nice. I hope Carl posted the library in the Census

Carl Nobile has developed and released an Arduino library covering the HC-SR04 ultrasonic sensor. He writes: “It features timing, metric conversion, and standard deviation methods, plus a few support methods. It is written in C++ to conserve the namespace. The conversion formula can be easily modified to optimize the accuracy of conversion at different distances for inches and centimeters. Multiple buffers of different lengths can be created for determining standard deviation.

Look at the code and examples to understand how the library works. The standerd deviation code can be removed from the compilation resulting in a significant savings of resources. To do this comment the #define COMPILE_STD_DEV definition in the header file.”

Remix Domestic Appliances

Tuesday, October 18th, 2011

[Elvia Vasconcelos] developed a very simple yet interesting installation based on PureData and Arduino. The main goal is change / remix (and therefore innovate) the approach toward domestic appliances:

To re-purpose an object is to manipulate its construction. I believe there is nothing natural about the way objects behave and therefore in their potential to be reinvented. It is in the artistic domain to liberate these objects from the settings in which they have become predictable and accepted. For this installation I am looking at objects from the Home. I present a fan, an extractor, a light bulb and a vacuum cleaner that are pretending to be toasters. They are controlled by the viewer via a telephone. My work is guided by a desire to hold onto things but not exactly to hold them in place.
