Of course, we wouldn"t just leave you with a datasheet and a "good luck!".For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and Development Kit at the bottom of this page.

As we all know, though LCD and some other displays greatly enrich the man-machine interaction, they share a common weakness. When they are connected to a controller, multiple IOs will be occupied of the controller which has no so many outer ports. Also it restricts other functions of the controller. Therefore, LCD2004 with an I2C bus is developed to solve the problem.

I2C bus is a type of serial bus invented by PHLIPS. It is a high performance serial bus which has bus ruling and high or low speed device synchronization function required by multiple host system. I2C bus has only two bidirectional signal lines, Serial Data Line (SDA) and Serial Clock Line (SCL). The blue potentiometer on the I2C LCD2004 is used to adjust backlight to make it easier to display on the I2C LCD2004.

I²C (Inter-Integrated Circuit), pronounced I-squared-C, is a multi-master, multi-slave, single-ended, serial computer bus invented by Philips Semiconductor (now NXP Semiconductors). It is typically used for attaching lower-speed peripheral ICs to processors and microcontrollers. Alternatively I²C is spelled I2C (pronounced I-two-C) or IIC (pronounced I-I-C).

I²C uses only two bidirectional open-drain lines, Serial Data Line (SDA) and Serial Clock Line (SCL), pulled up with resistors. Typical voltages used are +5 V or +3.3 V although systems I²C (Inter-Integrated Circuit), pronounced I-squared-C, is a multi-master, multi-slave, single-ended, serial computer bus invented by Philips Semiconductor (now NXP Semiconductors).

I²C uses only two bidirectional open-drain lines, Serial Data Line (SDA) and Serial Clock Line (SCL), pulled up with resistors. Typical voltages used are +5 V or +3.3 V although systems with other voltages are permitted.

3) Find the file LiquidCrystal_I2C which you just download. Click it open and then you"ll be prompted by "Library added to your libraries. Check "Import libraries"”. You also can see the libraries just imported have appeared on the list by Sketch->Include Library->LiquidCrystal_I2C.

If everything is correct,But the display just shows 16 black rectangles on Line 1.it may be the address of i2c is not 0x27,therfore you need to run the following code to read the address,then modify the 0x27 to which you read.

Features：IIC/I2C interface was developed to reduce the IO port usage on Arduino board.* Old 1602 screen requires 7 IO ports but this module uses only two.* Much needed control panel IO ports can be used to add some sensors, SD card and so on.* A New High-Quality 4 Line 20 Character Lcd Module.* Potentiometer can be adjusted to control the contrast.* Back light can be turned off by removing the jumper on the back panel.Specification:* Interface: I2C* I2C Address: 0x27* Pin Definition : GND、VCC、SDA、SCL* Back lit (Yellow with Black char color)* Supply voltage: 5V* Size : 60mm×99mm* Contrast Adjust : Potentiometer* Backlight Adjust : Jumper

The LCD has always been a device that acts as a window in human-computer interaction. For example, the prompt window on some instrument devices, the temperature and humidity prompt box, the device running status monitor, and the prompt screen of the counting device all have LCD figures.

It is a high-performance serial bus with bus rules and high-speed or low-speed device synchronization required for multi-master systems. The I2C bus has only two bidirectional signal lines, a serial data line (SDA) and a serial clock line (SCL).

4 line, 20 positions alphanumeric LCD 2004 with HD44780 (or compatible) display controller and the standard 4/8 bit parallel interface. The available I2C interface (option) fits right on the back of the display and turns its interface from parallel to simple 2-wire I2C (perfect for microcontrollers like Arduino to save on I/O ports).

4×20 blue LCD character display with bright white LED backlight, high contrast, and optional serial interface (I2C, SDA/SCL) for microcontrollers. The display needs a 5V power supply for operation. With the I2C interface installed, the backlight can be controlled by software as well. Many different libraries for different programming languages and controller families are available, also countless examples.

LCD Display Module I2C 20x4 Blue Arduino -  If your current LCD is frustrating you because it occupies all your GPIO pins and lacks characters" space, it is time to replace it with this one. This LCD Display Module uses an I2C communication interface, which only needs 2 wires to display information on any microcontroller-based project, including the Arduino. It is capable of displaying 4 lines of 20 white characters on a blue background. Moreover, it is compatible with either 3.3V or 5V logic systems, which is basically everything in programmable electronics.

A regular LCD is substantially more difficult to connect than an I2C LCD. Instead of 12, only 4 pins must be connected. Start by connecting the GND pin to the ground and the VCC pin to the Arduino"s 5V output. The I2C communication pins are all that is left at this point. Keep in mind that the I2C pins on each Arduino board vary and must be linked appropriately. The SDA (data line) and SCL (clock line) are located on the pin headers close to the AREF pin on Arduino boards with the R3 configuration. They also go by the names A5 (SCL) and A4 (SDA).

To power, the LCD, connect the Arduino"s USB port. The backlight will be visible lighting up. You will now begin to see the first row of rectangles as you adjust the potentiometer"s knob. Congratulations if that occurs! Your LCD is operational. After completing this, we can begin programming the LCD.

You must first install a library called LiquidCrystal I2C to drive an I2C LCD. The LiquidCrystal library that comes with your Arduino IDE has been improved by this library.

You can narrow your search by entering "liquid-crystal." Several entries ought to be present. Look for Frank de Brabander"sLiquidCrystal I2C library. Select Install after clicking that entry.

As was already said, the manufacturer determines the LCD"s I2C address. The default I2C address for LCDs powered by Texas Instruments PCF8574 chips is 0x27Hex. The default I2C address for LCDs powered by NXP Semiconductors" PCF8574 chip is 0x3FHex.

Therefore, your LCD"s I2C address is most likely 0x27Hex or 0x3FHex. However, it is advised that you ascertain the LCD"s precise I2C address before utilizing it. Fortunately, there is a simple method for doing this, due to Nick Gammon.

A straightforward I2C scanner sketch created by Nick scans your I2C bus and gives the addresses of each I2C device it encounters. Launch your Serial Monitor after loading this sketch onto your Arduino. You get to see the I2C address of your I2C LCD.
