I'll test the code in the morning.

#define LED 13
#define BUTTON 7

int val = 0;
int state = 0;

void setup {
  pinMode(LED, OUTPUT)
  pinMode(BUTTON, INPUT)
}

void loop {
  val = digitalRead(BUTTON);
  
  if (val == HIGH && state == 0) {
    digitalWrite(LED, HIGH);
    pause(500);
    state = 1;
  }
  if ((val == HIGH) && (state == 1)){
    digitalWrite(LED, LOW);
    pause(500);
    state = 0;
  }
}
