LCD2004 Parallel LCD Display with IIC/I2C Interface

A display is required if you wish to provide your Arduino projects any visual output. The LCD2004 Parallel LCD Display with IIC/I2C interface is a suitable option if you only require a little amount of data to display.

For your project, this display offers an easy and affordable way to incorporate a 20×4 White on RGB Liquid Crystal Display. White text on a blue background with a high contrast is displayed in a 20 character by 4 line format.

This blue backlight LCD display is excellent. For projects based on Arduino, it is excellent. It is quite simple to interface this blue-backlit display with an Arduino or other microcontroller.

This display solves the problem with the LCD2004 Parallel LCD Display, which required approximately 8 pins on your Arduino to power on. Fortunately, an I2C converter is soldered directly onto the display pins in this device. Therefore, just the I2C pins—which display a decent library and minimal coding—need to be connected.

Two bidirectional lines, known as SDA (Serial Data Line) and SCL (Serial Clock Line), are used by the Philips-developed I2C serial bus type. It is necessary to link both using pulled-up resistors. The standard voltages for usage are 3.3V and 5V.

The wiring is rather simple if the I2C adaptor is already soldered onto the board, as it is with this package. Generally, you only need four pins to connect. GND and VCC, naturally. 5 volts are needed to operate this display. Thus, we target the 5V pin.

Simple text or numerical values read by the sensors, such as temperature or pressure, or even the number of cycles the Arduino is executing, can be displayed on the display.

Features :
