Wiring (16-Pin Parallel):

For simplified connections, use an I2C adapter to reduce the pin count and streamline wiring.

Usage Tips:

• Adjust the contrast using a 10K potentiometer connected to the V0 pin for optimal display quality.
• For I2C, ensure the proper library (like LiquidCrystal_I2C) is installed for easy interfacing.
• Use a 220Ω resistor for the backlight to prevent excessive current flow and prolong its life.
