| + | * **void loop()**: | ||
| + | * Verify if the button has been pressed | ||
| + | * If the button has been pressed the Buzzer starts and makes a noise every second for 5 seconds | ||
| + | * The LCD displays that the sensor is reading | ||
| + | * After 5 seconds the buzzer stops | ||
| + | * The code computes the average value read by the sensor | ||
| + | * The condition blocks inside the code verify the value and display the appropriate message | ||
