Denver writes that he has created a Morse Code generator, and posted a tutorial in my blog about how it is done. His tutorial begins with an explanation of how Morse Code is organized and proceeds to explain the process of writing an Arduino sketch to produce the sequences of “dits” and “dahs” corresponding to […]

Arduino code emulation object for Parallax Propeller
If you regularly use the Arduino, but want to explore the versatile multi-core environment of the Parallax Propeller, here’s a code project of interest. Perry Harrington has written a Propeller SPIN code object to emulate many of the functions found in the Arduino SDK. Perry describes his code: This is a basic _light_ implementation of […]
Rescuing an ArduinoBT board with the Bus Pirate
Rohit de Sa has used the Bus Pirate with STK500v2 firmware to rescue a damaged ArduinoBT board. A few days ago I help a friend recover his ArduinoBT board. He had somehow managed to mess up the Bluetooth bootloader on the Arduino, and with wireless comms being the only way to program the board, he […]
How to make a CheerLights controller with Arduino and ioBridge
CheerLights is an ioBridge Labs project that allows people’s lights all across the world to synchronize, stay linked based on social networking trends. It’s a way to connect physical things with social networking experiences and spread cheer at the same time. We are all connected. The Arduino is used to generate the PWN signal to […]
Arduino 1.0 released
The Arduino team has released the official version 1.0 of the Arduino IDE. New features include changing the file extension for sketches to “.ino”, new toolbar icons, the Serial class (as well as other classes inheriting from Stream, like EthernetClient, SoftwareSerial, Wire and more) now contains functions for parsing incoming data, support for DHCP and […]
Arduino 1.0 IDE code available for preview
Arduino team member David Mellis says: I have Arduino 1.0 uploaded and ready for release, but it would be great if you could try it out as a sanity check before I announce it. You can find links to the download for Linux, OS X and Windows here. Via Adafruit.
ProtoStack ATmega328 kit review and Arduino clone build
Here is a comprehensive review of the ProtoStack ATmega328 kit that Eric won in the 7400 contest. He was pleasantly surprised that Protostack included an USBasp AVR programer. The review goes into detail on how to build a Arduino clone on this development kit. I managed to get my 7400 Logic PLL Based Switcher in […]
Parallax KickStart tutorials
Anticipating an increase in interest in their products now carried at Radio Shack and other retailers, Parallax has posted a number of useful tutorials on their Getting Started with Parallax Wiki Google code site. Designed to bring beginners up to speed with coding and interfacing peripherals with the Propeller multi-core MCU, the Basic Stamp module […]
GKOS keyboard for Arduino
The Global Keyboard Open Standard (GKOS) is an ongoing project to implement the full qwerty keyboard on a set of 6 keys. It is intended for use with tiny wireless terminals in order to minimize the space requirements. The standard was first published in 2000 and has been the subject of ongoing development. You can […]
Defcon 19: Network Monitoring with Arduino
Steve Ocepek, Director of Security Research, Trustwave SpiderLabs presented this talk at Defcon 19 (2011). He harkens back to the days of blinking modem lights, and demonstrates how to create a modern day “blinking light” network monitoring device using the Arduino Uno along with itead Studio’s Color Shield. Dubbed the cerealbox, this design interfaces with […]
Colornode holiday lighting microcontroller board
ColorNode is a wireless Arduino-compatible microcontroller board designed to replace the stock controller board on GE Color Effects light strings. It’s a project designed by digitalmisery and was inspired by deep darc’s Hacking Christmas Lights project last year. The schematic and photos are available, and they promise to post the code as soon as the […]

One of it’s main goals is to bring closer physical computing and robotic platforms to primary schools, kids and beginners.” You can download this Beta version for Windows and OSX here.
Radio Shack’s Great Arduino Challenge
Radio Shack has begun their Great Arduino Design Challenge. They’re seeking the project that best shows how you can use Arduino in a creative and innovative way. Check out the contest’s webpage for rules and all the details.
Matatino lets Arduino connect to Mac apps
Robotgrrl posted a link to her coding project Matatino, “a Cocoa framework for Mac that provides a straight-forward way to communicate with your Arduino through its serial connection.” Matatino is an open source project. You can learn how to add Matatino to your Xcode project at Robotgrrl’s Apps4Arduino site. Via the Arduino blog.
The human side of Arduino
Carlos made a mosaic picture of the Arduino board from faces of the Arduino Playground group on LinkedIn. The mosaic is made from 190 individual profile pictures. A zoom-out video of the mosaic is featured below. Via the contact form.

Irongeek’s Teensy based SD keylogger
Adrian Crenshaw (“Irongeek”) has released the project details and code for his latest hardware keylogger. If you have a Teensy board and ever thought about experimenting with keyloggers you’ll find everything you need in Adrian’s project description. You simple connect the Teensy between a female PS/2 connector and an SD card adapter and grab the […]
PID library for Arduino
Arhi tipped us to a PID library for Arduino. If you require precision control of electro-mechanical devices like heaters, servos, water pumps, etc. PID is one way to implement that control. It is an algorithm that controls a device by constantly adjusting its control or power signals to keep the device at preset state. Using sensors […]
Light sequencing and decoding DMX with Arduino
Akiba of Freaklabs and the Tokyo Hackerspace has written an excellent tutorial on using the Arduino to decode the DMX protocol, a standard protocol for stage lighting displays. It includes a three-part video presentation (Part I, above) and a link to the source code. As Akiba notes, these techniques could be used in developing some […]
