Photocopier

Projects General Guidance
1

I am working on building a photocopier that shoots paper everywhere for the musical 9 to 5 which is playing at my local High School tomorrow night Thursday May 16, 2013.

Basically it has one feeder motor, one "setup" motor, and an air valve.

I have everything working except for the "setup" motor.

The "setup" motor has to run for about 5s on start up.

The code I have written so far is pasted below.

char state_this = 'f';
 
boolean getBut1()
{
  return digitalRead(7) == HIGH;
}

boolean getBut2()
{
  return digitalRead(8) == HIGH;
}

void setMotorOff()
{
  analogWrite(6,0);
}
 
void setMotorSlow()
{
  analogWrite(6,200);
}
void setMotorFast()
{
  analogWrite(6,255);
  analogWrite(5,255);
}
void setMotor2On()
{
  analogWrite(9,255);
}
void setMotor2Off()
{
  analogWrite(9,0);
}

void setup()
{
  Serial.begin(9600);                // Set up serial communication at 9600bps

  pinMode(7,INPUT);
  pinMode(8,INPUT);
  pinMode(6,OUTPUT); 
  pinMode(5,OUTPUT);
  pinMode(9,OUTPUT); 
}

 void loop()
 {
   char state_next;
   boolean b1,b2;

   state_next = state_this;
   
   b1 = getBut1();
   b2 = getBut2();
   t1 = Time1();
   t2 = Time2();
   
   if   (state_this == 'f') {
     if      ( t1)      state_next = 's';
     else if ( b2)      state_next = 'f';
     else if ( b1)      state_next = 'a';     
   }
   else if (state_this == 'a') {
     if      ( t1)      state_next = 's';
     else if ( b2)      state_next = 'f';
     else if (!b1)      state_next = 'A';     
   }
   else if (state_this == 'A') {
     if      ( t1)      state_next = 's';
     else if ( b2)      state_next = 'f';
     else if ( b1)      state_next = 'b';
   }
   else if (state_this == 'b') {
     if      ( t1)      state_next = 's';
     else if ( b2)      state_next = 'f';
     else if (!b1)      state_next = 'B';
   }
   else if (state_this == 'B') {
     if      ( t1)      state_next = 's';
     else if ( b2)      state_next = 'f';
   }
   else if (state_this == 's') {
     if      ( t2)      state_next = 'f';
     else if (!t1)      state_next = 'S';
   }
   else if (state_this == 'S') {
     if      ( t2)      state_next = 'f';
   }
   else {
                        state_next = 'f';
   }
  
   if (state_this != state_next) {

     // actions when entering a state 
     if      (state_next == 'f') {
        setMotorOff();
        setMotor2Off();
     }
     else if (state_next == 'a') {
        setMotorSlow();
     }
     else if (state_next == 'A') {
     }
     else if (state_next == 'b') {
        setMotorFast();
     }
     else if (state_next == 'B') {
     }
     else if (state_next == 's') {
        setMotor2On();
     }
     else if (state_next == 'S') {
     }
   }
   
   state_this = state_next;
   delay(10);
 }

I need help figuring out how to trigger time1 at times less than 5000ms and time2 at times greater than 5000ms.

I tried doing this using millis for my time value, but found out that I could not compare it to a number.

Any help would be greatly appreciated as I only have tonight to finish it.
