Technical detail of my artwork

Arduino 1

/*
Name of Arduino COM4
Program for Art Work
Version 1.4
Huge 7 segment controller with Shift registor.
Made by Shotaro N 2010

note:
Somehow,you need Serial.print(); in a function of block();.
It does not do anything, but without having it, the program does not work properly.
Ver 1.1 added relay control and LEDcontrol
Ver 1.2 fixed a relay proglem
Ver 1.3 added a daisy chain pulse controller
Ver 1.4 change daisy chain controller from transistor to relay

/*
Program for second Arduino
Ver 1.3

Serial in Watcher "1" got data from daisy chain
Serial in Watcher "2" got data from ultrasonic range finder
Serial in Watcher "3" got data from motion sensor

Ver 1.0 basic
Ver 1.1 error correction about values
added while loop to fix communication Arduino and Isadora
Ver 1.2 fixed motion sensor value
Ver 1.3 fixed problem especially reset commend
Ver 1.4 take out motion sensor and reduce pressure to a computer
