Arduino Servo Shield Sequencer with 256K External EEPROM

The Servo Shield Sequencer works great for short sequences, up to 255 steps, but what if you need more than 255 steps?

tronixstuff has a very good tutorial showing just how easy it is to add external I2C EEPRom to the Arduino. Within 10 minutes you can go from having only 1Kbyte of EEPRom on the Duemilanove to having 256Kbytes using a 24LC256.
