Prac 11

This Arduino code reads temperature data from a DHT11 sensor connected to pin 12. It continuously monitors and updates the maximum and minimum temperatures recorded, displaying them in both Celsius and Fahrenheit. The program includes error handling for sensor reading failures and prints relevant temperature information to the serial monitor.
