Michu shared his IKEA Expedit shelf RGB LED mod ExpeditInvaders. He connected 40 RGB LED modules and a keyboard to an Arduino to make a color changing Ikea bookcase: I just finished my project “ExpeditInvaders”, a spiced up Ikea shelf! I added 40 LED modules to it and glued a keyboard on the bottom of […]

Arduino Robot shield
This is an Arduino shield intended for robotics prototyping. It features a DC/DC power supply, a sonar obstacle sensor, and a IR remote control receiver. The idea behind this post is to bring together some robot designs and trasform them in a new device with new hardware and standard software (arduino of course) and so […]
SJS-ONE: Open, Arduino-Based Synth
The SJS-ONE is a digital software synthesizer with a dual analog filter designed as a shield for the Arduino Uno. Its name is derived from the venue where it was designed, the SyltJam 2011, which is an annual LAN-party like weekend event for synth-geeks in Malmö, Sweden. The description of the original DIY version can […]
Black Hat hacker gains access to 4 million hotel rooms with Arduino microcontroller
This hack was demonstrated by Cody Brocious, a Mozilla software developer, at the Black Hat security conference in Las Vegas. At risk are four million hotel rooms secured by Onity programmable key card locks. According to Brocious, who should be scolded for not disclosing the hack to Onity before going public, there is no easy […]
RoboBrrd Brain board v2 gEDA design time-lapse video
Watch Erin design RoboBrrd’s Brain board v2 in gEDA from start to finish. RoboBrrd is an interactive robot designed to motivate students by responding to their achievements through chirps and dances. The original brain of the RoboBrrd was an Arduino MEGA, but the latest version will feature a custom Arduino compatible board. Since redesigning RoboBrrd […]
Hack: Fit an Arduino on a breadboard
Here is simple hack that allows you to use a breadboad with the Arduino. Alex simply bent the Arduino’s digital IO header so it would fit the standard 0.1” pitch of breadboards. Via the forum.
Arduino task scheduler
Brad shared an Arduino library he wrote schedules when specific functions will be executed. The code is open source and available on github. This library allows you to create a schedule queue of functions to be executed at specified times, on specified intervals. For example, say you’re trying to log some sensor data and update […]
OpenWRT router interfaced to an Arduino
Yesterday we talked about the cheap OpenWRT supported TP-Link WR703N Wi-Fi router. This instructable describes how to interface it to an Arduino board, and compares it to other Linux boards like the Raspberry Pi. So far the nicest solution I have found is one of the world’s smallest pocket routers TP Link WR703N. Cheapest in […]
Arduino based line following robot
Erdabyz finalized his Arduino-based line following robot. The design is open source and you can download the project files in the forum. He has 20 board which he’d sell for $3.5 +shipping. Via the forum.
Arduino shield roundup
Squonk found this list of 288 Arduino shields, from 116 makers, including pictures, license and pinouts. Looks pretty comprehensive, and includes some we’ve never heard of. Via the contact form.
Q&A with the developers of Codebender web-based Arduino IDE
Codebender is a new web-based development environment for the Arduino. Everything happens online, they even figured out how to upload new sketches from the browser. Before you groan about another locked-up software as service startup hear this: it’s open source! We talked to Codebender about the project. Walk us through your project Our goal is […]
Nimbits 3.2 released
The Nimbits crew is proud to announce the release of Nimbits v3.2. It is now easier than ever to get started using the public Nimbits cloud. Nimbits.com is a free, open source platform for logging and visualizing data on the cloud. It is a service you can use out of the box to log changing […]
Interfacing the LTC2440 24bit ADC with the Arduino
Jbeale shows how to interface the LTC2440 24bit analog to digital converter with the Arduino. He provided the pin connections, a small sketch, as well as some advice to get it up and running. I should add: to reach the specified noise performance of this part (200 nV RMS) you must have an absolutely clean […]
New app for Mac gives speech to your Arduino
Here is a voice synthesizer app for Mac giving your Arduino speech capability. You simply send strings over the serial port and the app reads them out. Speech for Arduino supports all voices on your Mac. You are able to change the pitch, rate, and volume straight from the window. You can also use various […]
BTSwitch project controls devices with Android smartphone
Luca Dentella writes, “Hello! I’ve just published my latest project, an Arduino-based bluetooth switch you can control via Android App.” The design uses an Android smartphone app which communicates via Bluetooth with a Bluegiga WT11 module, which in turn communicates with an Arduino controlling a relay switch. Luca’s plans and code are available on his […]
Arduino from the command line in Ubuntu 12.04
Martyn Davis is an Arduino enthusiast whose operations have outgrown the stock Arduino GUI IDE. “If you’ve done more than a bit of programming in the past, you’ll soon find the dinky IDE a little frustrating to use. For example, my preferred text editor, by far, is vim, and I find it quite jarring to […]

ROBOTC for Arduino public BETA released
The ROBOTC dev-team has released their first Public BETA of “ROBOTC for Arduino”. “ROBOTC is a powerful C-based programming language with a Windows environment for writing and debugging programs, and the only programming language at this level that offers a comprehensive, real-time debugger.” It has previously been released in a paid version for the the […]
Tutorial: Accurate Arduino ADC readings
The Hardware Hacking guys have posted this brief tutorial with tips on improving the accuracy of ADC reading with the Arduino. They endeavor to do this by measuring the internal 1.1V reference voltage (it is available for ATMega 168 and ATMega 328 only) and, then, by normalizing the ADC. Via the Arduino Blog.
