LCD2004 Parallel LCD Display with IIC/I2C Interface

If you’re looking to incorporate visual output into your Arduino projects with minimal pin usage, the LCD2004 Parallel LCD Display with IIC/I2C interface is an excellent solution.

This display offers a simple and cost-effective way to integrate a 20×4 White on RGB Liquid Crystal Display into your project. With a 20-character by 4-line configuration, it displays clear and high-contrast white text against a blue background with backlight.

Ideal for Arduino-based projects, this display with a blue backlight is easy to interface with Arduino or other microcontrollers. Notably, this product addresses the pin usage concern of the standard LCD2004 Parallel LCD Display. Instead of occupying about 8 pins on your Arduino, this version comes with an I2C adapter directly soldered onto the display pins. This simplifies the connection to just the I2C pins, requiring minimal coding effort and showcasing compatibility with a good library.

The I2C (Inter-Integrated Circuit) is a type of serial bus that uses two bidirectional lines, SDA (Serial Data Line) and SCL (Serial Clock Line). The I2C interface simplifies connections and supports both standard 5V and 3.3V usage voltages.

If you already have the I2C adapter soldered onto the board, like in this product, the wiring is quite easy. You should usually have only four pins to hook up. VCC and GND of course. This display works with 5 volts. So we go for the 5V pin.

The values shown on the display can be either simple text or numerical values read by the sensors, such as temperature or pressure, or even the number of cycles that the Arduino is performing.

Features:

1. Arduino IIC/I2C interface was developed to reduce IO port usage on the Arduino board
2. I2C adapter allows flexibility in connections
3. I2C reduces the overall wiring.
4. 20 characters wide, 4 rows
5. White text on a Blue background
6. Single LED backlight included can be dimmed easily with a resistor or PWM.
