Inarticulate Eloquence Opens and Closes with the Sun

Here is the code for our Hoberman Surface. For include statements, blogger likes to take the <> as HTML code, so I just took them out. Also, if statements with > < etc are changed to 'is less than' 'is greater than' etc to prevent the same issues.

The Stepper Motor - Arduino

#include afmotor.h

AF_Stepper LeftMotor(48, 1);
int position = 1;

void setup() {
Serial.begin(9600);
Serial.println("Stepper test!");

LeftMotor.setSpeed(250);
}

void loop() {
if(Serial.available()){
Serial.println("Available");
char ch = Serial.read();

switch(ch){
case '+':
if (position == 0){
LeftMotor.step(2250, FORWARD, SINGLE);
position = 1;
Serial.println(position);
}
break;
case '-':
if (position == 1){
LeftMotor.step(2250, BACKWARD, SINGLE);
position = 0;
Serial.println(position);
}
break;
}
}
}

The LDR - Arduino

int PhotoA = 3;
int LEDpin = 13;
int valueA = 0;
int threshold = 500;

void setup(){
pinMode(PhotoA, INPUT);
pinMode(LEDpin, OUTPUT);

Serial.begin(9600);
}

void loop(){
valueA = analogRead(PhotoA);

if (valueA is less than threshold){
digitalWrite(LEDpin, HIGH);
Serial.print('+');
}
else {
digitalWrite(LEDpin, LOW);
Serial.print('-');
}

delay(1000);
}

The Link - Processing

import processing.serial.*;

Serial MotorPort;
Serial LDRPort;

void setup()
{
size(720, 720);
colorMode(RGB, 1.0);
noStroke();
rectMode(CENTER);
frameRate(100);

println(Serial.list());
MotorPort = new Serial(this, Serial.list()[0],9600);
LDRPort = new Serial(this, Serial.list()[2],9600);
}

void draw()
{

char ch = LDRPort.readChar();
MotorPort.write(ch);

}

Fairly simple code this time. Got the job done.
