To display text on an I2C LCD 1602A display with Arduino, you will need to connect the display to your Arduino board, install the necessary libraries, and write code to control the display.
Here are the basic steps to get started:
In this tutorial we will see how to display text in an LCD display with Arduino.
The Arduino UNO is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins, 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header, and a reset button. It is the most popular and widely used board among the Arduino boards.
The Arduino UNO can be programmed using the Arduino programming language, which is based on C++. It uses a simple and intuitive programming environment, making it easy for beginners to get started with microcontroller programming.
The Arduino UNO can be connected to various sensors and actuators to control different devices and perform different tasks. For example, it can be used to control motors, read data from sensors, display information on an LCD screen, and communicate with other devices via serial communication protocols such as I2C and SPI.
The Arduino UNO can also be powered by a USB cable or an external power supply, making it easy to use in a wide range of projects and applications. It’s compatible with a wide range of shields (expansion boards) that adds functionality to the board, such as Ethernet, WiFi, and Bluetooth, and it’s widely supported by a strong and active community, which provides a lot of tutorials, examples and libraries to help users to get the most of the board.
LCD I2C 160A display
An LCD I2C 160A display is a type of liquid crystal display (LCD) that uses the I2C communication protocol and has a screen size of 160×128 pixels. The I2C (Inter-Integrated Circuit) protocol is a communication protocol that allows multiple devices to communicate with each other over a shared bus. This means that the LCD display can be connected to a microcontroller, such as an Arduino, using just two wires for communication and power.
The I2C interface allows for a simpler wiring and board design, and also multiple LCD can be connected to a single microcontroller by just changing the I2C address of each display. The size of 160×128 pixels provides a decent resolution for displaying text, images or graphics.
This type of LCD display can be used in various projects such as in home automation, weather station, data logger, etc. It’s also compatible with many development board like Raspberry Pi, Arduino, etc.
Connecting wires are used to connect various components in an electronic circuit. They allow for the transfer of electricity, data, or signals between different devices and components.
When connecting wires to an Arduino or other microcontroller, it is important to pay attention to the correct pinout. The pinout refers to the arrangement of pins on the microcontroller and the corresponding function of each pin. The Arduino pinout can be found in the documentation provided by the manufacturer, or in various resources available online.
To complete the assembly you must connect:
Here is the program to display text on the LCD display.
LiquidCrystal_I2C lcd(0x27, 20, 4);
lcd.init(); //display initialization
lcd.backlight(); // activate the backlight
lcd.setCursor(0, 0); // stand in the front line
lcd.print(" Carte"); // Display the word 'card' on the I2C LCD 1602 display
lcd.setCursor(0,1); // stand on the second line
lcd.print(" Arduino"); // Display the word 'Arduino'
Note: You must download the LiquidCrystal_I2C library(Download).
