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

motion sensor information

Since we have two different motion sensor this link will help to use the motion sensor which I did not make tutorial.

Check below link to see the first motion sensor tutorial.

http://art-research2010summer.blogspot.com/2010/06/sensor-motion-sensor.html

http://www.eathertons.com/blog/?p=73

The most different point of these two motion sensor is that the colors of the wire are different so that we need to change the connection of the wire and the motion sensor that is talked in the link require a resistor.

I think it is a good idea to reduce the delay  time in a program that was introduced in the link so that the motion sensor works more ideally.  Also I preferred to use a more higher resistor that the resistor that was used in a tutorial so that you can get more good data from the motion sensor. 

 

Isadora setup

Serial In watcher will control everything, so that Arduino can control everything.

Somehow Isadora's picture player does not work properly. Even I send a value 0 to turn off visibility, it does not work. Only wave generator can controll on and off.

 Also "Gate" does not work for picture player.

Arduino Daisy Chain 2

Program for Arduino Daisy Chain

This program is specifically designed to communicate with Isadora.

You can use this program as a switch in Isadora.

Program for a host Arduino

/*

this program is just send on and off signal to client Arduino every 2 second

*/

int signalPin=3;
void setup(){
pinMode(signalPin, OUTPUT);

digitalWrite(signalPin, LOW);
}
void loop(){
 
digitalWrite(signalPin, HIGH);
delay(2000);
digitalWrite(signalPin, LOW);
delay(2000);
}

Program for a Client

int ReadingPin = 0;
int val;
void setup(){
Serial.begin(9600);

}
void loop(){
val = analogRead(ReadingPin);

/*

with this "if" commend, Arduino does not send any data to Isadora when an analog pin receive nothing.

*/
  if (val>100){
  val=1;//you can change value to anything you want 
Serial.print(1,DEC);
Serial.print (val, DEC);
Serial.println();
delay(50);
}
}
