The LCD displays the fan state and the temperature from LM35 sensor.
Conditions:
Temperature < 30 --> FAN OFF
Temperature >= 30 --> FAN speed = 25% of Max Speed
Temperature >= 60 --> FAN speed = 50% of Max Speed
Temperature >= 90 --> FAN speed = 75% of Max Speed
Temperature >= 120 --> FAN speed = 100% of Max Speed
