On/Off with Soft-start

Projects Programming
4

Thank you very much for your answer! Here is my CODE. But is not good because, when I push the button and keep push, is OK. But I need only ON/OFF. When I push the button (TL2) (not keep pressed) only push, the program go in to Start mode (R+G led light and relay1) for 3 sec. And again when I push the same button, the program is going to OFF mode (Red LED and Relay1 and Relay2 + Green LED is OFF).

const int button = 0;    //button on my shield TL2
const int relay1 = 8;    //relay1 this relay on for 3 sec when LED_R + LED_G is light (in shield is YELLOW LED)
const int relay2 = 7;    //relay2 this relay is on when the LED_G is light (in shield is BLUE LED)
const int led_R = 5;     //this LED light when is START mode or OFF mode
const int led_G = 6;     //this LED ligh when is START mode or ON mode

        //record the current button state

enum { Off = LOW, On = HIGH };  // relay on when HIGH
int buttonState;
#define RelayPeriod     3000    // how long to relay1 is ON
unsigned long  msecRelay;
int  relayState = Off;

void setup () {    
  pinMode (button, INPUT_PULLUP);
  pinMode (relay1, OUTPUT);
  pinMode (relay1, OUTPUT);
  pinMode (led_R, OUTPUT);
  pinMode (led_G, OUTPUT);
  digitalWrite (relay1, Off);
  digitalWrite (relay2, Off);
  digitalWrite (led_R, On);
  digitalWrite (led_G, Off);
  buttonState = digitalRead (button);

}


void loop () {
unsigned long msec = millis ();
    // check for button press
    byte but = digitalRead (button);
    if (buttonState != but) {
        buttonState = but;
        delay (25);                         // debounce

        if (LOW == but)  {

            if (On == digitalRead (relay1))  {
                digitalWrite (relay1, Off);
                digitalWrite (relay2, Off);
                relayState = 0;
                digitalWrite (led_G, Off);
                digitalWrite (led_R, On);
            }
            else  {
                digitalWrite (relay1, On);
                digitalWrite (relay2, Off);
                digitalWrite (led_R, On);
                digitalWrite (led_G, On);
                relayState = 1;
                msecRelay = msec;
            }
        }
    }
    if (relayState && (msec - msecRelay) >= RelayPeriod)  {
        // turn off
        digitalWrite (relay1, Off);
        digitalWrite (relay2, On);
        digitalWrite (led_G, On);
        digitalWrite (led_R, Off);
        relayState = 0;
    }
}

PS: i found this code and I editting for me, but is not good. Origina this CODE : Switch a fan on for 5 seconds and then turn off - #4 by gcjr
