Broken laptop recovered using Arduino

When Jack the Vendicator’s laptop display malfunctioned, he thought all was lost. He developed a rescue strategy using an Arduino as a USB bridge between the laptop and a desktop PC. He plugged the Arduino into the laptop, and connected a USB serial converter from his desktop computer to the Arduino’s serial pins. In effect […]

Arduino EMF detector

High electromotive force/electromagnetic field (EMF) readings can cause interference with precision electronic equipment, and have even been associated with paranormal/spirit activity! DTN’s blog has an Arduino project designed to detect high EMF levels. It uses an Arduino mega with a 4 inch wire antenna on pin 31 and 16 LEDs for indicators. Source code is […]

Wireshark analysis of wireless protocols

FreakLabs has an interesting project designed to conduct sniffing of protocols that ride on top of 802.15.4 such as Zigbee and 6LoWPAN (IPv6 over 802.15.4). The project utilizes their FreakDuino platform which contains an Arduino integrated with a wireless radio. The tutorial assumes that Wireshark is installed on your computer, the Chibi or chibiArduino release […]

OBDuino: car diagnostics with Arduino

The OBDuino is an in-car real-time display of various information, like speed, RPM, instant fuel consumption or average trip fuel consumption as well as others PIDs supported by the car. It reads the data from the car’s OBD-II connector, interfacing it via a MC33290 chip to the Arduino which processes the CAN data and outputs […]

HUGE wireless RGB LED display

siklosi saw the post about using a wifi router as an Arduino wireless serial connection, and shared his own take. This RGB LED wall is plays Winamp visualizations, and more. The LEDs are driven by Rainbowduinos, the Rainbowduinos are connected to the PC using the router as a wireless serial connection. I made this “little” […]

Arduino + MQ3 = alcohol breath tester

This the season for good cheer, and what can be more cheerful than a project that’s as much fun to use as it is to build? How about a homebrew alcohol breath tester? Daniel Andrade shows how to build just such a device using just an Arduino, MQ3 alcohol sensor and a handful of resistors […]

Codebox: save Arduino sensor data to Google

Many are familiar with how to read data from Arduino into Processing. One such example varies the a PC’s onscreen graphics relative to the intensity of light on an LDR. Here MAKE presents a project which web enables Arduino sensor projects, allowing Processing data to be communicated and stored in a Google spreadsheet doc.

Plumbing: Parallel programming for the Arduino

Concurrency.cc has introduced Plumbing, a Creative Commons licensed introduction to programming the Arduino using the programming language occam-pi. The tools are open source and facilitate parallel processing within the Arduino. The most recent versions for Windows, Mac and Linux are available for download. Check our the free PDF book download.
