• LCD Overview: LCD (Liquid Crystal Display) screens are electronic modules widely used in devices and circuits. The 16x2 LCD refers to the display's capability of showing 16 characters per line, with 2 lines in total.
• Character Display: Each character is rendered in a 5x7 pixel matrix, and the display can show 224 different characters and symbols.
• Registers: The LCD has two main registers:
  • Command: Handles instructions to the display (like clearing the screen).
  • Data: Stores the information to be displayed (like characters and numbers).
