    This program uses an LPC214x microcontroller to detect obstacles using an infrared sensor connected to pin 24 of port 1. It initializes an LCD display using several command codes. The main function sets the directions of ports 0 and 1, initializes the LCD, displays an initial string, and enters a loop to continuously check the infrared sensor. If an obstacle is detected, it displays a message on the LCD, otherwise it clears the first LCD line. It defines separate functions for sending command and data to the LCD, and for sending a null-terminated string to the LCD.
