2. Display the current temperature value on an LCD.
3. Regulate the speed of the motor according to temperatureT:
T ≥ 75 °C: The motor reaches its maximum forward speed.
45 °C ≤ T ≤ 75 °C: Forward speed is raised.
10 °C ≤ T ≤ 45 °C: The motor stops.
0 °C ≤ T ≤ 10 °C: The motor rotates backward.
T ≤ 0 °C: The motor reaches its maximum backward speed.
