The buttons

To control the buttons we need to add a piece of code that is similar to the piece of code for the LEDs. The biggest difference is that we now work with buttons instead of LEDs.

        aantal = aantal+1; 
      }
      if (buttonCheck == 5){  // <----- vanaf hier
        aantal = 1;
        while (aantal < lengte){
            buttonState1 = digitalRead(BUTTON_PIN1); // <-updaten van de pinstatus
            buttonState2 = digitalRead(BUTTON_PIN2);
            buttonState3 = digitalRead(BUTTON_PIN3);
            
            if(buttonState1 == LOW){       
              digitalWrite(LED_PIN1, HIGH);
                aantal = aantal + 1;
                delay(500);
                  
            else if(buttonState2 == LOW){       
              digitalWrite(LED_PIN2, HIGH);
              aantal = aantal + 1;
              delay(500);
            }
            else if(buttonState3 == LOW){        
              digitalWrite(LED_PIN3, HIGH);
              aantal = aantal + 1;
              delay(500);
            }
            else{                           
              digitalWrite(LED_PIN1, LOW); 
              digitalWrite(LED_PIN2, LOW);
              digitalWrite(LED_PIN3, LOW);
            }
            
        }
      }          // <------ tot hier
      digitalWrite(LED_PIN1, HIGH);
      digitalWrite(LED_PIN2, HIGH);
      digitalWrite(LED_PIN3, HIGH);

To check if the right button was pressed I used the code below:

if(buttonState1 == LOW){       
              digitalWrite(LED_PIN1, HIGH);
              delay(250);
              buttonState = 1;
              if (1 == volgorde[aantal+1]){
                aantal = aantal+1;
              }
              else{
                aantal = lengte + 1;
                start = 1;
              }
            }

scoring

Of course we want to see our points if we are lost. This code shows the points by means of LED flickering.

      aantal = 1;
      
    } 
    
    if (start = 1){
      aantal = 0;
      while (aantal < lengte){
        digitalWrite(LED_PIN1, HIGH);
        delay(500);
        digitalWrite(LED_PIN1, LOW);
        delay(500);
        aantal = aantal +1;
     }
  
  }
  }
}

This is an example where I made a mistake.
