16x2 LCD Display

Description :

The JHD 16x2 Character LCD Display with Yellow Backlight is a popular liquid crystal display (LCD) module used in various electronic projects for displaying alphanumeric characters. It has a 16x2 character configuration, meaning it can display 16 characters in each of its two rows. The yellow backlight provides visibility in low-light conditions. Here are some key features and information about the JHD 16x2 Character LCD Display:

Key Features :

• Display Size : The display consists of 16 columns and 2 rows, allowing for the display of 16 characters per row.
• Character Set : The display is capable of showing alphanumeric characters, symbols, and custom characters.
• Backlight : The yellow backlight provides illumination to make the characters visible in low-light environments.
• HD44780 Controller Compatible : The display is often compatible with the HD44780 LCD controller, making it easy to interface with microcontrollers like Arduino.
• Parallel Interface : The JHD 16x2 LCD typically uses a parallel interface for communication with a microcontroller.
• Voltage Requirements : The module typically operates at 5V, which is a common voltage for interfacing with microcontrollers.

Pin Configuration :

The JHD 16x2 LCD module usually has the following pin configuration:

1. VSS (Ground): Connects to the ground (0V).
2. VDD (Power): Connects to the power supply (5V).
3. VO (Contrast Adjustment): Connects to a potentiometer for adjusting the contrast.
4. RS (Register Select): Used to select either the command register (RS = 0) or the data register (RS = 1).
5. RW (Read/Write): Used for selecting between read and write modes (usually tied to ground for write-only operations).
6. E (Enable): Enables the LCD for data read/write operations.
7. D0 to D7 (Data Lines): The eight data lines for transferring data to/from the LCD.
8. A (Anode): Connects to the anode of the backlight.
9. K (Cathode): Connects to the cathode of the backlight.
