Independent and random on and off times without delays

hello-
i have bank of intake solenoids have corresponding outtake solenoids.
for example if intake[0] on, outtake[0] must off. if outtake

• high, intake
• must low.

the high times (inwhoosh[]) , high times (outwhoosh[]) different.
the high-in times longer high-out times. high-in times should take random values inwhoosh[] array , high-out times should take random values outwhoosh[] array.

i've tried work out logic , came psuedocode. not sure correct, or how go it. in advance.

my psuedocode

code: [select]


if intake state high intake(random [i])
set corresponding outtake state low (series of if statements?)
if intake state high , it's been longer on interval
grab currentmillis , set previousmillis
set intake state low
go beginning

if outtake state high outtake(random [i]) , it's been longer off interval
grab currentmillis , set previousmillis
set outtake state high

my actual code

code: [select]

#include <streaming.h>                                                  // library formatting printf
#define solenoidcount 8
unsigned long previousmillis[8];                                        // store last time solenoid toggled
unsigned long interval[] = {1700,2000,1500,700};                          // interval time each solenoid on/off
int outtake[solenoidcount] = {1,2,3,4,5,6,7,8};                                  // intake pins
int intake[solenoidcount] = {9,10,11,12,14,15,16,17};                              // exhaust pins
unsigned long inwhoosh[] = {4000,4900,4200,4800,4100,4200,4900,4400};
unsigned long outwhoosh[] = {2000,3000,1800,3700,2000,1100,3000,2000};
long int count = 0;
int led = 13;
void setup() {                                                          // set digital pin output , initialize previousmillis
  serial.begin(9600);
    unsigned long thismilli = millis();                     
    for(int = 0; < 8; i++) {
      pinmode(intake[i], output);
      pinmode(outtake[i], output);     
      previousmillis[i] = thismilli;
      pinmode(led, output);
      digitalwrite(led, low);
  }
}

void loop() {
  unsigned long currentmillis = millis();
   for(int = 0; < 8; i++) {     
       if(currentmillis - previousmillis[i] > inwhoosh[i]) {         // switch states if current - previous > array value
       //if current millis( ones have been counting since arduino turned on) - previous millis(points value in array) > interval [points value in array]
       previousmillis[i] = currentmillis;                                    // save last time flipped solenoid 
          if (digitalread(intake[i])  == low) { 
          digitalwrite(outtake[i], low);
          digitalwrite(intake[i], high);
          delay(200);
          }
          else{
          digitalwrite(intake[i], low);
          digitalwrite(outtake[i], high);
          delay(200);
        }
       }
  }
}

change interval array value @ each pin state change.
