VD 2

This C program code defines constants and variables for controlling an LCD display and 7-segment LED display. It includes functions to check button presses, increment a counter when a limit is exceeded, display time and productivity statistics on the LCD, and light up the 7-segment LED display to show the current time. The main loop continuously calls functions to update the displays and check for user input.
