As of Arduino 1.0, interrupts are not supported on the Arduino Leonardo. I’m working on a project using the atmega32u4 with the Arduino IDE which needs interrupt support for both software serial and frequency counting, so I investigated ways to…

PCB Desktop Background
Want a nice hearty printed circuit board desktop background? Well, here you go (right-click, save as). The PCB is an older Arduino NG board placed on top of one of our 10W MNLC lighting nodes (still under development, more information…
RGB Multi-Node Lighting
This project uses the open-source i2c RGB LED controller firmware “cyz_rgb” to create a modular high-power lighting network. The network is controlled by an Arduino, which scans the network for nodes controls them autonomously with onboard scripts, manually via serial…
ZonCoffee .2 Released
ZonCoffee is a full-featured PID controller package for Arduino, customized for use with espresso machines. ZonCoffee is written in Processing/Wiring, and includes some code from Tim Hirzel‘s BBCC project.
EC155 PID with Arduino
This is a build log of my PID modification to my DeLonghi EC155 espresso machine. Currently, the machine uses an Arduino to drive a solid-state relay controlling the heating coil. The Arduino displays mode and temperature on a serial lcd,…
(Really) Cheap RFID door opener
Well, the school year is over, so I thought I’d post up some information about my (extremely cheap and junky-looking but functional) door opener.
Arduino Mobile Connectivity
Many DIY projects that people attempt these days include internet connectivity, logging, gps tracking, sensor data storage, and remote control. People have used xBee, GPS modules, and extra hardware to integrate all of these features, but there is a much…
Automatic Panoramas with Arduino and CHDK
Last year around this time, I posted some information about my automatic panorama-taking “robot” made with an arduino, and a Canon S3IS mounted on a stepper motor, but I never published it to a more exposed portion of the site.…
PanoBot
PanoBot is a rudimentary panorama-taking device for any Canon camera running the CHDK firmware. This project was made back in ’08 so there are numerous projects that are much more full-featured than this implementation; nevertheless, I am making the code…
