Piezo

this project is a switch case i whit one piezo it works but now in case 5 i while 2 piezo als trigger.

case 5:
          StartTime = millis();    //  start timer
          hit = 0;  // reset the number of times the target has been hit. you have 3 shots until it moves to the next one
          delay(RandomTime);
          while(hit < 1){
            //  read sensors for random mode
            HeadSensorReadingRandom = analogRead(HeadSensor);
            TorsoSensorReadingRandom = analogRead(TorsoSensor);
            LegSensorReadingRandom = analogRead(LegSensor);
            LegSensor1ReadingRandom = analogRead(LegSensor1);
            //  light the target to hit
            digitalWrite(Led4yellowPin, 1);
            digitalWrite(Led4redPin, 0);
            digitalWrite(Led4greenPin, 0);
            digitalWrite(Led1yellowPin, 1);
            digitalWrite(Led1redPin, 0);
            digitalWrite(Led1greenPin, 0);
            ActualTime = millis();  // measure the actual time
            Timeout = ActualTime - StartTime;   // calculate the time that has passed since the target was active
            // if the sensor reading is greater than the threshold:
            if (LegSensor1ReadingRandom >= sensitivity || HeadSensorReadingRandom >= sensitivity )  {
           
            while(HeadSensorReadingRandom>= false)
           {
            digitalWrite(Led4yellowPin, 0);
            digitalWrite(Led4redPin, 0);
            digitalWrite(Led4greenPin, 0);
           }
           if(LegSensor1ReadingRandom>= false)
           {
            digitalWrite(Led1yellowPin, 0);
            digitalWrite(Led1redPin, 0);
            digitalWrite(Led1greenPin, 0);
           }
                   
             // update the LED pin itself:
              wright(3);
              hit = 3;
            } 
            
            //if the target has been active for too long (more than 20s), you've timed out
            if (Timeout >= 4000) {
              wrong(15);
              hit = 3;
             RandomOFF = RandomOFF + 200;
              delay(15000);
            }
          }
          //  one less target to the end of random mode
          RandomOFF = RandomOFF + 1;
          break;
