LCD 16×2 Blue with I2c #931

Description

An “LCD 16×2 Blue with I2C” is a specific type of alphanumeric display module featuring a 16×2 character configuration (16 characters in each of the 2 rows) with a blue backlight and equipped with an I2C (Inter-Integrated Circuit) interface. These displays are commonly used in various electronic projects for showing information, messages, and data in a human-readable format. Here are the key details:

1. **LCD Display**: The “16×2” specification means that the LCD screen can display up to 16 characters in each of the 2 rows, resulting in a total of 32 character positions for displaying text, symbols, or data.

2. **Blue Backlight**: The “Blue” indicates the color of the backlight for the LCD. The blue backlight provides a visually appealing and often easily readable display.

3. **I2C Interface**: The I2C interface simplifies the connection and control of the display with a microcontroller or other devices. It uses the I2C communication protocol, reducing the number of required pins and simplifying the wiring.

4. **Character Display**: These displays can show alphanumeric characters, symbols, and custom characters, making them suitable for displaying various types of information and messages.

5. **Contrast Adjustment**: Some of these displays include a potentiometer for adjusting the contrast, allowing you to control the visibility of the characters.

6. **Compatibility**: LCD 16×2 displays with I2C are often used with microcontroller platforms like Arduino, Raspberry Pi, and others. A variety of libraries and code examples are available to facilitate their integration into projects.

7. **Applications**: These displays are commonly used in DIY electronics projects, temperature and humidity monitors, time and date displays, instrumentation, and other applications that require human-readable information.

When working with an LCD 16×2 Blue with I2C, you’ll typically need to install the relevant libraries and write code to display the information you want. The I2C interface makes the connection process straightforward, usually requiring just two wires for communication (SDA and SCL), in addition to power connections. These displays are versatile and are widely used for user-friendly information presentation and feedback in various electronics and microcontroller-based projects.
