In this lesson we will show how to mount a LCD display on your Arduino using the I2C communication. Finally you will see how to program it with a simple example showing how to display text on the display.<\/p>\n<h1 id=\"2\">Preparations<\/h1>\n<h2 id=\"2.1\">Hardware<\/h2>\n<ul>\n<li>OSOYOO UNO Board (Fully compatible with Arduino UNO rev.3) x 1<\/li>\n<li>OSOYOO Magic I\/O Shield for Arduino x1<\/li>\n<li>I2C LCD 1602 Display x 1<\/li>\n<li>OSOYOO 4-Pin PNP Cable x 1<\/li>\n<li>USB Cable x 1<\/li>\n<li>PC x 1<\/li>\n<\/ul>\n<h2 id=\"2.2\">Software<\/h2>\n<ul>\n<li>Arduino IDE (version 1.6.4+)<\/li>\n<li><a href=\"https:\/\/osoyoo.com\/wp-content\/uploads\/samplecode\/LiquidCrystal_I2C.zip\" target=\"_blank\" rel=\"noopener noreferrer\">LiquidCrystal_I2C.h<\/a><\/li>\n<\/ul>\n<h1 id=\"3\">About I2C LCD 1602 Display<\/h1>\n<p><img class=\"aligncenter\" src=\"https:\/\/osoyoo.com\/picture\/Arduino_Graphical_Programming_Kit\/lesson14\/1602-1.png\" \/><\/p>\n<p>The integration of an LCD display greatly facilitates the interactivity of the project you are developing, allowing the user to directly read some output parameters. These values can be either a 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.<\/p>\n<p>However, these displays have a small problem. When they are connected to a microcontroller (such as Arduino for example), these displays require virtually many connection PINs occupying practically almost all available IO and leaving the multiprocessor few outputs for any other devices and sensors. This problem has been solved thanks to the communication on the I2C bus.<\/p>\n<p>The LCD1602 display has an integrated microchip that manages this type of communication, and then all of the input and output information are limited to only two PINs (excluding power supply). I2C is a type of serial bus developed by Philips, which uses two bidirectional lines, called SDA (Serial Data Line) and SCL (Serial Clock Line). Both must be connected via pulled-up resistors. The usage voltages are standard as 5V and 3.3V.<\/p>\n<p>The blue potentiometer on the I2C LCD1602 (see the figure below) is used to adjust the backlight for better display.And there is a jumper on the board, if you take away this jumper , the backlight will aways be off.<\/p>\n<p><img class=\"aligncenter\" src=\"https:\/\/osoyoo.com\/picture\/Arduino_Graphical_Programming_Kit\/lesson14\/7.png\" \/><\/p>\n<p>For the usagage of other functions, pleae refer to the &#8220;LiquidCrystal_I2C.h&#8221; in the sourcecode of <b><a class=\"external text\" href=\"https:\/\/osoyoo.com\/wp-content\/uploads\/samplecode\/LiquidCrystal_I2C.zip\" target=\"_blank\" rel=\"noopener noreferrer\">I2C LCD library<\/a>.<\/b><\/p>\n<h1 id=\"4\">Connection<\/h1>\n<p>First, please plug Osoyoo Magic I\/O shield into UNO board:<\/p>\n<p><img class=\"aligncenter\" src=\"https:\/\/osoyoo.com\/picture\/Arduino_Graphical_Programming_Kit\/lesson4\/UNO%2BBase-min.png\" \/><\/p>\n<p>Then connect the<u>\u00a0I2C LCD 1602 Display<\/u>\u00a0module to the\u00a0<u>I2C\u00a0<\/u>port of the Magic I\/O shield (please move the switch on the board to 5V) with a\u00a0<u>4-pin\u00a0<\/u>PNP cable as below:<\/p>\n<p><img class=\"aligncenter\" src=\"https:\/\/osoyoo.com\/picture\/Arduino_Graphical_Programming_Kit\/lesson14\/base%2B1602.png\" \/><\/p>\n<h1 id=\"5\">Find the I2C address<\/h1>\n<p>Each device has an I2C address that it uses to accept commands or send messages. For Uno board, this address usually is 0x27. But sometimes the address might be changed 0x37,0x24 \u2026., So let\u2019s go and look for the one on your device.<\/p>\n<p><a href=\"https:\/\/osoyoo.com\/download\/code\/ic2_scanner.zip\" target=\"_blank\" rel=\"noopener noreferrer\">Download ic2 scanner sketch zip file<\/a> , then unzip and load it into Arduino IDE. By opening up the serial monitor in the upright corner, Arduino will scan the address range looking for a reply. Most Arduino board will show 0x27, however it be other number.<\/p>\n<p><a href=\"https:\/\/osoyoo.com\/wp-content\/uploads\/2017\/07\/scanneri2caddress.png\"><img loading=\"lazy\" class=\"wp-image-8386 aligncenter\" src=\"https:\/\/osoyoo.com\/wp-content\/uploads\/2017\/07\/scanneri2caddress.png\" alt=\"\" width=\"765\" height=\"419\" \/><\/a><\/p>\n<p>Write down the Address that you have found, you\u2019ll need it in the next step.<\/p>\n<h1 id=\"6\">Upload Sketch<\/h1>\n<p>After above operations are completed, connect the Arduino board to your computer using the USB cable.
