Arduino lcd library sda scl serial#
If characters arrived over the serial port.
Initialize the serial port at a speed of 9600 baud Set the LCD address to 0x27 for a 16 chars and 2 line display
Lcd.setCursor(0,1) //Defining positon to write from second row,first column. ĭelay(1000) //Delay used to give a dynamic effect Lcd.print(" Tech Maker ") //You can write 16 Characters per line. Lcd.setCursor(0,0) //Defining positon to write from first row,first column. lcd.backlight() // To Power OFF the back light Lcd.backlight() //To Power ON the back light The blue color component you have seen in the above picture is a potentiometer which is used to adjust the brightness of the display. If you properly have seen the picture above, you will see a black adapter. That black adapter uses the PCF8574T IC chip which converts I2C serial data to parallel data for the LCD display. Jumper Wires Pin Configuration of I2C LCD Display I2C protocol is also known as 2 line protocol. By seeing the above example you may know the advantage of I2C protocol. If you use I2C LCD display, you need only just 4 connection. If you use normal LCD display, you need a total number of connections are 12. One of the best things about using I2C is we can reduce the connections (wiring).
This is usually used to communicate between one master and multiple slaves. I2C (I-square-C i.e IIC) means inter-integrated communication protocol. Before starting this article we will see what is i2c.

In this tutorial, you will see how to connect i2c LCD display (Liquid Crystal Display) to Arduino using the i2c module.
