All you need to know about I2C LCD screens on an Arduino Uno. I2C Liquid Crystal Displays. All you need to know about I2C LCD screens on an Arduino Uno. Nov 11, 2019
To connect an LCD I2C module to your Arduino, you will need the following components - Arduino Board e.g., Arduino Uno - LCD I2C Module 16x2 or 20x4 - Jumper Wires - Breadboard optional - Power Source USB cable or external power supply Wiring Diagram. The wiring for connecting an LCD I2C module to an Arduino is simple.
Arduino I2C Pins . The Arduino Uno board has only one I2C module, but it provides these SDA and SCL line at two different locations. Note While communicating with devices using I2C communication protocol, pull-up resistors should be used. The value of pull-up resistors may vary depend upon devices used. I2C functions for Arduino. Wire.write data
The following image shows the circuit diagram for Arduino I2C demonstration between two Arduino UNO boards. Code. In order to program the I2C peripheral in Arduino, you need to understand the Wire library. This is the main library that allows you to communicate with I2C or TWI Devices over the I2C Bus SDA and SCL lines. Wire Library
Initialize pin 13 of the Arduino as an output pin using pinMode Add the blink logic code inside the loop The Wire Library. To use the Arduino's built-in I2C interface, we will use the Wire library. This library is included with the Arduino IDE, so there's no need to install it.
Introduction. A good way of adding complexity of features to your projects without adding complexity of wiring, is to make use of the Inter-integrated circuit I2C protocol.
The module has 16 pins that can be directly connected to the display, or you can test the connection in breadboard, as I did riding the circuit below where I used a 162 LCD display with HD44780 controller connected to the Arduino Uno If you are using an Arduino Mega 2560, use the pin 20 SDA and 21 SCL
This circuit features an Arduino Nano connected to an OLED display and a DS3231 real-time clock RTC module for displaying the current time. The Arduino Nano is powered through a toggle switch connected to its VIN pin, with power supplied by a TP4056 charging module that charges and manages two 3.7V LiPo batteries connected in parallel.
Arduino Code Working Explanation. To interface the I2C LCD with Arduino UNO connect the circuit according to the diagram given above. Write the above-mentioned code of determining the 12C address in your Arduino IDE and upload the code in Arduino UNO. Open the serial monitor and wait until the device is found.
