Briefly: I would like to turn on a relay for 30 seconds, after I toggle a switch on.

I'm trying to do a blinds automation at home.

I have a simple ON-OFF-ON switch, attached to an Arduino connected to Relays. 

I want to turn on Relay#1 for a maximum of 30 seconds if I toggle the switch down from center. In other words, relay turns on when I switch, and when timer reaches 30 seconds relay turns off.

similarly I want to turn on Relay#2 for exactly 30 seconds if I toggle the switch up from center

And when I switch back to center, I would like the timer to reset.

I could not figure out how. Could anyone help?

I have been trying to use elapsedMillis library for this, which is a nice library that helps me avoid using Delays:
<http://playground.arduino.cc/Code/ElapsedMillis>

However even though I could work the relays without the 30 second limitation, I couldn't figure out the code to end working of the relays. Here is my current code:

```
      #include <elapsedMillis.h>
    #define RELAY_ON 0
    #define RELAY_OFF 1

    #define RELAY1_TURNS_ON_BLINDS  5
    #define RELAY2_SHUTS_DOWN_BLINDS 6

    #define shutswitch A0
    #define openswitch A1

    bool LocalCommandToOpen;
    bool LocalCommandToShut;

    void setup() ////////SETUP////////
    {
    digitalWrite(RELAY1_TURNS_ON_BLINDS, RELAY_OFF);
     digitalWrite(RELAY2_SHUTS_DOWN_BLINDS, RELAY_OFF);

     pinMode(RELAY1_TURNS_ON_BLINDS, OUTPUT);
     pinMode(RELAY2_SHUTS_DOWN_BLINDS, OUTPUT);

     pinMode(shutswitch, INPUT);
     pinMode(openswitch, INPUT);
        } ////SETUP

  void loop() { ///////LOOP
         if (digitalRead(shutswitch) == 1)
     {
       LocalCommandToOpen = 1;
     }
     else
     {
       LocalCommandToOpen = 0;
     }

      if ( digitalRead(openswitch) == 1)
     {
       LocalCommandToShut = 1;
     }
     else
     {
       LocalCommandToShut = 0;
     }

    unsigned int CloseInterval = 14000;
     elapsedMillis timeElapsedSinceCloseButtonPush = 0;
     unsigned int OpenInterval = 14000;
     elapsedMillis timeElapsedSinceOpenButtonPush = 0;

     //MANUAL SWITCH OPERATION

     if ( LocalCommandToShut == 1 )
     {
       digitalWrite(RELAY1_TURNS_ON_BLINDS, RELAY_OFF);
       digitalWrite(RELAY2_SHUTS_DOWN_BLINDS, RELAY_ON);
     }
     else
     {
       digitalWrite(RELAY2_SHUTS_DOWN_BLINDS, RELAY_OFF);
     }

    //MANUEL DUGME ILE ACMA
     if ( LocalCommandToOpen == 1)
     {
       digitalWrite(RELAY2_SHUTS_DOWN_BLINDS, RELAY_OFF);
       digitalWrite(RELAY1_TURNS_ON_BLINDS, RELAY_ON);
     }
     else
     {
       digitalWrite(RELAY1_TURNS_ON_BLINDS, RELAY_OFF);
     }

     delay(500);

    } /////////////////LOOP////////////////////////////////////
