16x2 LCD display - Green backlight

Character Display: The display consists of 16 columns and 2 rows of characters, allowing it to display a total of 32 characters at once.

Alphanumeric Characters: It can display alphanumeric characters (letters and numbers), symbols, and custom characters if supported by the controller.

Backlight: The "GREEN" designation indicates that the LCD has a green backlight. This backlight provides illumination to the characters, making them visible in low-light conditions.

HD44780 Compatible: Many 16x2 LCD displays use the HD44780 controller, which is a widely used and well-documented controller chip. This compatibility ensures ease of use and compatibility with various microcontrollers and development platforms.

Parallel Interface: Typically, these displays are interfaced with microcontrollers using a parallel interface. They require multiple GPIO pins for data and control signals.

Voltage and Contrast: The LCD module usually operates at 5V or 3.3V and may require an adjustable contrast control to set the display's readability.

Character Size: The characters are typically 5x8 dots in size, but some displays support custom characters for creating custom symbols or icons.

Applications: 16x2 LCD displays are widely used in various applications, including:

• Embedded systems and microcontroller projects
• Temperature and humidity displays
• Digital clocks and timers
• Data loggers and instrumentation
• Home automation and control panels
• Consumer electronics devices

Library Support: Many microcontroller platforms have libraries or code examples available to simplify interfacing with 16x2 LCD displays.

Serial Adapters: Some modules come with I2C or SPI serial adapters, making them easier to interface with microcontrollers that have limited GPIO pins.
