Indispensable Arduino to RaspPi transition link

So you finally got a Pi and fired it up with Wheezy. Now what? Everyone's talking about using it with an Arduino-this will teach you how to eliminate the middle man. A good primer on Linux and Python too. Once you get the LED blinking don't forget to kill the process with a before you close the Bash or it will go on until you unplug the power.

New improved I2C library for Arduino

Recently I have been experimenting a lot with I2C. My A.I. project uses the DS1307 RTC and a work project uses several I2C ADC's.

Normally the Arduino Wire library works fine with the DS1307 RTC but it does not play well with 3.3V @ 8MHz devices such as my Micro Magician and does not support fast mode (400KHz). It also has some compatibility issues with some devices such as my ADC's because it does not support a repeated start condition.
