I may have to use this to communicate with the Arduino :

Gives serial access to PHP under linux, OSX and Windows (write-only under Windows).
This class can be used to communicate with a serial port under Linux, OSX or Windows.

I like this little Applescript proxy for use with the Arduino.

Basically it can interpret data (characters) sent from the Arduino and send them on to other programs

Control your Mac from Arduino, the easy way
A while ago I wrote a small app that would execute AppleScript commands depending on the data send from an Arduino board connected to my mac. I’ve been asked a few times to release it but it was just a quick hack. Now thanks to HyperWerk in Basel, I’ve had the time to fix it a bit for a student project. I’m releasing it to see what people do with it.

This website has a number of very basic experiments to start out with fairly advanced electronic components and the Arduino.

Working with analog input
Dimmer: Fading an LED with a Potentiometer
Drawing a graph of analog input
Thresholding with a Range Sensor
Tilt control with an Accelerometer
Understanding Voltage Dividers with a Flex Sensor
Flex sensor
Force Sensitive Resistor (FSR) Thumb Wrestling

A project I like (because it triggered a idea for a project I can do) - where the Author as added a Arduini board to his doorbell, whihc now send a signal to his Mac Mini every time the doorbell is pressed, and in turn sends out a message through Twitter!

I want to do the same with the catflap we have - as it is a RFID enabled I can even detect which cat has entered the house (or left the house) - more about that in a later posting.

Doorbell update

Quick update to last week’s post about the doorbell project. I’ve now squeezed in into an Altoids tin (surely everybody’s favourite project box), complete with a little hole for the radio antenna. It’s now permanently connected to the Mac Mini in the living room, meaning roo_house on Twitter now makes an update (”There’s somebody at the door”) when the bell is pushed.

Interesting - CPAN has a library to interface with a Arduino to use a Ardunio equipped with a LCD display!

The Arduino is an open-source physical computing platform. Among the many things one might want to do with such a device is connect an LCD to it and print stuff (at least that's what I wanted to do with it).

There are a couple of excellent low-level libraries that can be linked into an Arduino sketch to provide this functionality. I've chosen the LCD4Bit library to link against. The PerLCD sketch provides a few higher level functions as well as a serial listener.
