Do you want to test your next Mac OS X-to-Arduino project without always having the Arduino available? Do you want to test you cool Processing application when your mate hasn't finished writing the Arduino sketch? Do you want to do test driven development of your Mac OS X based application without dependency on your microcontroller? If the answer to any of these questions is yes, then VirtualSerialPortApp is for you!

This is an overview of the hardware/software/services I used:

A LDR (light dependent resistor) is glued on the on/off led of the coffeemachine. When the coffeemachine is switched on the led turns on, the ldr detects this light. This LDR is connected to an Arduino microcontroller, Processing reads the value from the Arduino using Firmata and Processing sends this to a php file which will send it to Twitter.

Fritzing is an open-source initiative to support designers, artists, researchers and hobbyists to take the step from physical prototyping to actual product. We are creating this software in the spirit of Processing and Arduino, developing a tool that allows users to document their Arduino and other electronic-based prototypes, and to create a PCB layout for manufacturing.

This tutorial introduces a Processing interface sketch provides a GUI for the command-line interface written into the Arduino RFID example. You should read that tutorial first. The sketch shown here also allows you to upload tags it reads to O’Reilly’s Emerging Technology Conference attendee portal, and retrieves the resulting profile. The API for this was written by Edd Dumbill. The Processing sketch retrieves RFID tags from the Arduino reader serially, then passes the tag via a HTTP request to a PHP script on a remote server, shown below, that adds an authorized login to the O’Reilly site.

This tutorial shows how to make an Arduino-based RFID reader that reads Mifare tags and stores them in EEPROM. It is a modification of Alex Zivanovic’s code on Tinker.it. Thanks to Alex and Massimo Banzi for the reference. Once you’ve got it running, go on to the RFID to Web example, which provides a Processing interface sketch provides a GUI for the command-line interface written into the Arduino code.

The Arduino meets Processing project intends to make it as easy as possible for anyone to explore the world of physical computing. All you need is an Arduino board as well as the Arduino and Processing software, which you can download on their project websites.
