This is a 20x4 Arduino compatible LCD display module with high speed I2C interface. It is able to display 20x4 characters on two lines, whitecharacterson blue background.

Generally, LCD display will run out of Arduino pin resource. It needs 6 digital pins and 2 power pin for a LCD display. If you want to build a robot project, it will be a problem with Arduino UNO and LCD display.

This I2C 20x4 LCD display module is designed for Arduino microcontroller. It is using I2C communication interface, With this I2C interface, only 2 lines (I2C) are required to display the information on any Arduino based projects. It will save at least 4 digital / analog pins on Arduino. All connector are standard XH2.54 (Breadboard type). You can connect it with jumper wire directly.

This 1602 LCD module has 8 I2C address in all, from 0x20 to 0x27. You can set one according to your requirements, avoiding the confliction of I2C address. And its contrast can be adjusted manually.

RC2004A is 20 characters x 4 lines monochrome LCD display module. The RC2004A LCD display has the same specs as RC2004A1. The only difference between them is the position of pins. RC2004A has 16pins on the PCB; pins of RC2004A1 are on the FFC connector. Default interface of RC2004A LCD display is 6800 with built-in IC ST7066; if you require interface such as SPI or I2C, they’re available as well, but the IC will be replaced with RW1063. Power supply of LCD display RC2004A is 5V (3V is optional). Negative voltage version is available for 3V power supply.

Raystar provides various LED backlight combinations for RC2004A display LCD, such as white, yellow-green, amber, red and RGB. You can choose module with LED backlight or without it. There are many LCD modes to choose from, including STN negative, blue ; STN positive, gray/yellow-green ; FSTN positive, white ; FSTN negative, black. RC2004A display LCD 20x4 offers a selection of fonts, for instance, English/Japanese, Europe and Cyrillic (Russian), etc. If you’d like to obtain full datasheet of LCD 20x4, please contact us for more info!

On previous tutorials on our website, we have covered the use of several displays, LCDs, and TFTs, with diverse Arduino boards. From Nokia 5110 LCD display to different types of OLEDs, the reason for the tutorials has been to ensure that, as a reader, you know how to use many of the most popular displays so this help you make the best choice when trying to select the perfect display for your project. For today’s tutorial, we will continue in that line and examine how to use the 20×4 I2C Character LCD Display with Arduino.

The 20×4 LCD display is essentially a bigger (increased number of rows and columns) version of the 16×2 LCD display with which we have built several projects. The display has room to display 20 columns of characters on 4 rows which makes it perfect for displaying a large amount of text without scrolling. Each of the columns has a resolution of 5×8 pixels which ensures its visibility from a substantial distance. Asides its size, the interesting thing about this version of the display being used for today’s tutorial is the fact that it communicates via I2C, which means we will only require 2 wires asides GND and VCC to connect the display to the Arduino. This is possible via the Parallel to I2C module coupled to the display as shown in picture below. The I2C module can also be bought individually, and coupled to the 16 pins version of the display.

To demonstrate how to use this display, we will build a real-time clock which will display date and time on the LCD. To generate and keep track of date and time, we will use the DS3231 Real time clock. We covered the use of the DS3231 RTC module in the tutorial on DS3231 based Real-time Clock, you can check it out to learn more about its use with the Arduino.

To write the code for this project, we will use three main libraries; the DS1307 Library to easily interface with the DS3231 module, the liquid crystal I2C library to easily interface with the LCD display, and the Wire library for I2C communication. While the Wire library comes built into the Arduino IDE, the other two libraries can be downloaded and installed via the links attached to them.

As mentioned during the introduction, our task for today is to obtain time and date information from the RTC module and display on the LCD. As usual, I will do a breakdown of the code and try to explain some of the concepts within it that may be difficult to understand.

We start the code by including the libraries that will be used. After which we create an object of the Liquid crystal library, with the I2C address of the LCD as an argument. The I2C address can be obtained from the seller or as described in our tutorial on using the 16×2 LCD display to ESP32.

Next, we create a set of variables which comprises of byte arrays that represent custom characters to be created and displayed.  The custom characters are usually 5pixels in width and 8 pixels in height, representing each box in the rows or columns of the LCD. The byte array represents which pixels of the box to be turned on or off.

Next, we write the void setup function and start by initializing the library using the lcd.begin() function, with the first argument representing the number of columns, and the second argument representing the number of rows. After this, the CreateCustomCharacters() function is called to convert the char variables created above into characters that can be displayed on the LCD. One of the characters created is then used to create a UI/frame which is displayed using the printFrame() function.

The first function is the printTime() which breaks down the time data stored in the “tm” variable to extract seconds, minutes and hour values. These values are then displayed on the LCD using the lcd.print() function.

The printDate function is similar to the printTime function. It extracts date information from the variable tm and uses the lcd.print() function to display it.

The printFrame() function, on the other hand, was used to create a sort of user interface for the project. it makes use of the characters created above. Each of the custom characters created is displayed using the lcd.write(byte(x)) function with x being the character number of the character to be displayed. The characters are positioned on the LCD using the lcd.setCursor() function which takes numbers representing the column and row on which the character is to be displayed, as arguments.

The original iBook"s only customer-serviceable parts were the RAM and AirPort card, accessed via two slots under the keyboard. No other modifications were possible in-warranty. There was no PCMCIA port for additional expansion capabilities. 40 screws needed to be removed to access the hard drive. The optical drive, however, can be accessed far more easily, requiring only 11 screws and one standoff to be removed. Later on, some users transplanted a 1024×768 LCD from the more recent white iBook into a clamshell iBook. This is only possible with the "FireWire" and "FireWire SE" models, as they have 8 MB of video RAM; the older ones only have 4 MB.
