Arduino realtime audio processing

Lab3, the Laboratory for Experimental Computer Science at the Academy of Media Arts Cologne, posted this tutorial on how to perform realtime audio processing with an Arduino. They explain: This is an experiment to show how some realtime audio processing can be done with the Arduino. The first set of examples alter an incoming audio […]

Arduino Ethernet + SD card tutorial

Ladyada has posted this detailed tutorial over at Adafruit on using Ethernet and SD card with Arduino. It describes how to use the Arduino to browse files on an SD card remotely. This tutorial is targeted at those who already have quite a bit of Arduino or microcontroller experience and are ‘fluent’ in C/C++/Java!

EasyMSP 0.8.2 Beta2 released

MattTheGeek has released his early project code for EasyMSP, which allows MSP430 users to run Arduino code with few modification, thanks to EasyMSP’s AFI, or Arduino Function Interface. The purpose of this project is to create a user friendly dev environment for MSP430 MCUs, seeking to accommodate both beginners and advanced users by providing the […]

Extreme electric motorcycle uses Arduino

This article from MIT News highlights the MIT Team’s recent entry into the Isle of Man TT Race, a speed competition for all-electric vehicles conducted over a 37.7 mile circuit. Race coordinators put up a prize of £10,000 for the first electric bike to finish with an average speed of 100 miles per hour or […]

Android Arduino MIDI sequencer

Here’s a project from SuLuLab using an Android smartphone to send commands via WiFi to an Arduino board in order to control a MIDI sequencer. It uses the new Processing 1.5 which provides Android support. SuLuLab writes: The first application developed to study the new Processing mode is a graphical interface for the simple MIDI […]

Update on Arduino imaging – Processing sketch + video

Earlier this week we posted about Carlos Agell’s project which allows the acquisition of analog camera images by an Arduino. Carlos has updated this project for use with a Processing sketch instead of the costly LabVIEW required in the original design. Here’s the link to his compressed file containing the Arduino and Processing sketches, LabVIEW […]

Image acquisition from an analog camera using Arduino

Carlos Agell of Hacking Electronics has developed this project which allows the acquisition of analog camera images by an Arduino. He uses an Arduino, Nootropic’s video experimenter shield, 1% resistors and a potentiometer. This hardware captures a 128×96 monochrome image and sends it back via serial to a PC where it can be viewed using […]

Pachube controlled RGB LED

Andy from the UK was looking to build a simple proof of concept project which would integrate an Arduino and ENC28J60 based ethernet shield (or a Nanode) to connect with his Pachube account to control an RGB LED. He says: This article describes a simple application to demonstrate the ENC28J60 EtherShield library. It can be […]

Command line LCD Arduino interface

Joseph Swanson from swantron likes working with the command line. He also likes working with the Arduino. So he came up with this simple project which takes the results of his command line entries and directs them over the Linux box’s USB output to the Arduino. The Arduino then displays the data on an attached […]

Foosball table uses Arduino to put scores on web

The gang at SinnerSchrader have combined their love of foosball and their passion for digital solutions to make the world’s first digital foosball game. The project uses optical sensors to detect the scoring of goals. These sensors are read with the Arduino which sends it over WiFi to the server which then makes it available […]

Arduino to Android IO on the cheap (aka Poor Man’s NFC)

Joe Desbonnet was looking for a cheap and easy way to transfer data from an Arduino to an Android device. The hack he devised requires only a 1-meter length of wire wound into a coil, a resistor and diode. He writes: This is a little hack that allows very low bandwidth communications in one direction […]

Microchip chipKIT giveaway and free shipping

Octal posted a free shipping coupon for Microchip’s new chipKIT 32bit Arduino-compatible platform. This is Microchip’s grab for some of the Arduino crowd action. They released an Arduino processing-based interface with sort of open compiler. Arduino sketches compile and run on the PIC chipKIT platform without any code changes. FREE shipping coupon for the new […]

Web interactive LCD controlled by Arduino

Here’s a project by Everett Robinson which demonstrates how to use an Arduino, Ethernet shield, 2×16 LCD, a breadboard and 2K resistor to produce a web-controlled interactive LCD display. The Arduino generates a simple HTML web page showing the text currently displayed on the LCD, providing an input form to change the LCD text, resulting […]

Openenergymonitor

emonTx stands for Energy Monitoring Transmitter. It’s a small, open source wireless energy monitoring node. It’s based on the Arduino (Atmega328) and is fully compatible with the Arduino IDE and programmed via an FTDI to USB cable. It’s designed to take inputs from multiple CT sensors, optically from a pulse-output utility meter and from multiple […]

Android ADK with a standard Arduino Uno and USB host shield

Rather than wait for the pricey Google ADK hardware, Mario Bohmer decided to hack away at Android accessory development on his own. Since the Google firmware was based on their dev board, he had to port the firmware and software for use with the Arduino Uno and a USB Host Shield. He reports success using […]

SoundAffects turns sounds of city into music

SoundAffects is a project designed to turn streets sounds into music. It uses an Arduino to read data from street level sensors measuring temperature, light, color, weather, cell phone activity, noise and proximity. This data is then processed using a combination of Jitter, MaxMSP and Ableton Live to produce dynamic musical compositions which passersby can […]
