Referring to the LCD16020, I believe that everyone is not unfamiliar the square shape, green color, a row of 2.54 pin header.... LCD1602 module is a product of the DFRobot Gravity IIC series, which has been greatly optimized for its original LCD1602 appearance. This module does not need to adjust the contrast, retain the backlight controllable function, simultaneously compatible with 3.3V and 5V voltage. The optimization of function and the appearance brings you the different experience. This kind of module has the blue screen, the green screen, the gray screen.

Follow the pin description to connect the hardware, then download the sample code to UNO. After upload finished, you can see the LCD display and backlight gradient effect.

Have you been fed up with Black/White LCD screen? Do you want to try a colorful one? DFRobot I2C 16x2 Arduino LCD with RGB Backlight Display module will bring you a new experience about screen. It comes with RGB full color backlight, which has 16 million kinds of color.

Usually, Arduino LCD display projects will run out of pin resources easily, especially with Arduino Uno. And it is also very complicated with the wire soldering and connection. This I2C 16x2 LCD Screen is using an I2C communication interface. It means it only needs 4 pins for the LCD display: VCC, GND, SDA, SCL. It will saves at least 4 digital / analog pins on Arduino. And Gravity interface make it easier to use with our Gravity: IO expansion shield.

Accustomed to the same LCD screen, do you want to have a different experience? DFRobot LCD1602 will bring you a new visual feeling, It is not the same as the previous LCD monochrome screen, supports RGB full-color font, can provide 16 million kinds of color combinations. DFRobot Gravity I2C 16x2 Arduino LCD with RGB Font Display use universal Gravity I2C interface, it means only two communication lines, you can realize communication and backlight control. The LCD screen can display 2x16 characters, support screen scrolling, cursor movement and other functions. Through dedicated Arduino library, you can complete all the design without cumbersome wiring and complex code.

Follow the pin description to connect the hardware, and download the sample code to UNO, after upload is successful, you can see the LCD display and backlight gradient.

This LCD module uses a 128x64 liquid crystal display that support Chinese character , English characters and even graphics. It can exhibit 4 lines and 12 English characters/6 Chinese characters per line. It is suitable for interactive work with Arduino.

The following sample is working under SPI mode. It demonstrates how to display integers on the LCD scrren. You will need the Arduino Library which can be downloaded here.

This is a very popular LCD Keypad shield for Arduino or Freeduino board. It includes a 2x16 LCD display and 6 momentary push buttons. Pins 4, 5, 6, 7, 8, 9 and 10 are used to interface with the LCD. Analog Pin 0 is used to read the push buttons. The LCD shield supports contrast adjustment and backlit on/off functions. It also expands analog pins for easy analog sensor reading and display.

The LCD Keypad shield is developed for Arduino compatible boards, to provide a user-friendly interface that allows users to go through the menu, make selections etc. It consists of a 1602 white character blue backlight LCD. The keypad consists of 5 keys — select, up, right, down and left. To save the digital IO pins, the keypad interface uses only one ADC channel. The key value is read through a 5 stage voltage divider.

Creates a variable of type LiquidCrystal. The display can be controlled using 4 or 8 data lines. If the former, omit the pin numbers for d0 to d3 and leave those lines unconnected. The RW pin can be tied to ground instead of connected to a pin on the Arduino; if so, omit it from this function"s parameters. for example:

Initializes the interface to the LCD screen, and specifies the dimensions (width and height) of the display. begin() needs to be called before any other LCD library commands.for example:

The J1-J8 include the both the user interface, i.e. Analog pins, APC220(Serial) pins, Digital pins, and the pins connected with the lower Arduino card, e.g. Uno/ Leonardo. Here is a simple mapping picture.

It works well if uploaded by Arduino 1.5.3 version, however, the latest 1.6.* have discard pin Definition for Edison. So you have to add pinMode(); into the setup() like this:

Hello friends welcome back to Techno-E-solution, In previous video we see how to interface LCD 16×2 to Arduino Uno, but there are very complicated circuits, so in this tutorial, I"ll show you how to reduce circuitry by using I2C module which is very compact & easy to connection. Simply connect I2C module with LCD parallel & connect I2C modules 4 pins to Arduino. I2C module has 4 output pins which contains VCC, GND, SDA, SCL where 5V supply gives to I2C module through VCC & GND to GND of Arduino. SDA is a data pin & SCL is clock pin of I2C module. To interface LCD and I2C with Arduino we need Liquid Crystal I2C Library in Arduino IDE software.

To make this project we need Arduino Liquidcrystal library in Arduino IDE. Follow following steps to add this library in Arduino IDE software.Open Arduino IDE Software.

I forked johnrickman/LiquidCrystal_I2C and created a version that supports both Arduino and Raspberry PI (Linux I2C, really). For the most part, the source code is the same as what was forked, but it has been refactored so that the code that interfaces with the actual device (the platform-specific code) is instantiated in a compile-time factory. The example programs have been modified to work on both platforms. Autotools is supported on Linux, and there a library is created that can be linked to your source to get the platform-specific bits.

For those of your who might be wanting to support both Linux and Arduino platforms with a single set of code, even more so if you are coming from Arduino with code to port, you might find this implementation of the DFRobot I2C LCD code helpful.
