What is the use of I2C module for LCD?
I2C LCD Adapter This chip converts the I2C data from an Arduino into the parallel data required by the LCD display. The board also comes with a small trimpot to make fine adjustments to the contrast of the display. In addition, there is a jumper on the board that supplies power to the backlight.
What is I2C LCD display Arduino?
This is a 16×2 LCD display screen with I2C interface. It is able to display 16×2 characters on 2 lines, white characters on blue background. 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.
What are the advantages of using the I2C interface for connecting the LCD display?
An I2C LCD advantage is that wiring is straightforward, requiring only two data pins to control the LCD. A standard LCD requires over ten connections, which can be a problem if your Arduino does not have many GPIO pins available.
How do you control a character I2C LCD with Arduino?
Adjusting the contrast of the LCD On the I2C module, you will find a potentiometer that you can turn with a small screwdriver. Plug in the USB connector of the Arduino to power the LCD. You should see the backlight light up. Now rotate the potentiometer until one (16×2 LCD) or 2 rows (20×4 LCD) of rectangles appear.
Why I2C module is used?
I2C Bus enables 2 devices to communicate with each other in a stable, high-speed, bidirectional way and with the least I/O pins. I2C Bus utilizes 2 lines to communicate, Serial Data Line (SDA) and Serial Clock Line (SCL), so that the protocol I2C uses is also called “bidirectional” protocol.
How does I2C module work?
I2C is a serial communication protocol, so data is transferred bit by bit along a single wire (the SDA line). Like SPI, I2C is synchronous, so the output of bits is synchronized to the sampling of bits by a clock signal shared between the master and the slave. The clock signal is always controlled by the master.
How add I2C library to Arduino?
Go to the link and download the library Arduino-LiquidCrystal-I2C-library. Then open Arduino IDE and go to Sketch>Include Library> Add. ZIP Library. Next select the downloaded ZIP file and click open.

What is the purpose of I2C?
The I2C bus is a very popular and powerful bus used for communication between a master (or multiple masters) and a single or multiple slave devices.
What is I2C Arduino?
Arduino boards to share information with each other. The I2C protocol involves using two lines to send and receive data: a serial clock pin (SCL) that the Arduino Master board pulses at a regular interval, and a serial data pin (SDA) over which data is sent between the two devices.
How does I2C work on Arduino?
The I2C protocol involves using two lines to send and receive data: a serial clock pin (SCL) that the Arduino Master board pulses at a regular interval, and a serial data pin (SDA) over which data is sent between the two devices.
How to use the I2C protocol with an LCD display and Arduino?
To use the I2C protocol with an LCD display and Arduino, there is a special library to be downloaded and included in the code. The name of this library is Liquid Crystal I2C. Download the library, a zip file (you can download it from here) and extract the contents in the libraries folder of the Arduino IDE.
What is the voltage of the lcd1602 module?
Both must be connected via pulled-up resistors. The usage voltages are standard as 5V and 3.3V. The LCD1602 module consists of two parts. A classic standard LCD display HD44780 16×2 (16 characters on 2 lines). The backlight can be green or blue.
How does the I2C bus work on the lcd1602?
This problem has been solved thanks to the communication on the I2C bus. 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).
How to use liquid crystal I2C library in Arduino IDE?
The name of this library is Liquid Crystal I2C. Download the library, a zip file (you can download it from here) and extract the contents in the libraries folder of the Arduino IDE. You can do directly from the Arduino IDE, select Sketch > include Library > Add .ZIP library from the menu.
