Button not working correctly. Static bool, Potentiometer. uno

[miked34]

Ya I should have picked up on that sooner, I was focused on saving pins, but since I'm going to use two boards I have some pins to spare.

so from everyone's feed back this is my new wiring diagram for the pot and switch.

2 question:

1. can I connect the switch to an analog or pin, say A3 ? (how could I code A3 to supply voltage would that be the led flag) ?

2. If so, would I use the conditional approach or the Ledflag ?

conditional

@gcjr

 if (digitalRead(button) == HIGH)  {
        int myDelay = analogRead(A2);
        int Led     = random (2 , 13);

        digitalWrite(Led, HIGH) ;     // turn on the random LED
        delay(myDelay);
        digitalWrite(Led, LOW);       // turn off that led
        delay(myDelay) ;              // delay off for amount of time it was on
    }

Ledflag

@gcjr

const byte butPin = A1;
const byte ledPin = 13;

byte butLst;

void setup ()
{
    pinMode (ledPin, OUTPUT);
    digitalWrite (ledPin, HIGH);

    pinMode (butPin, INPUT_PULLUP);
    butLst = digitalRead (butPin);
}

void loop  ()
{
    byte but = digitalRead (butPin);
    if (butLst != but)  {
        butLst = but;
        delay (20);         // debounce

        if (LOW == but)
            digitalWrite (ledPin, ! digitalRead (ledPin));
    }
}

Thanks !
