In this tutorial you will also learn how the same i2c 16×2 LCD can be interfaced with the Nodemcu ESP8266 Wifi Module which used in IOT based projects. In this tutorial, you will learn how to display text on the i2c 16×2 LCD using Arduino. This type of the LCD can be interfaced with any controller board using only 2 wires. The i2c 16×2 LCD is in fact the same LCD but it comes with the i2c driver module soldered on the backside of the LCD

The wiring can be reduced by replacing a regular 16×2 LCD with the I2C supported 16×2 LCD. A regular 16×2 LCD module needs a lot of wires, due to which maximum of the controller I/O pins are wasted. For displaying the Date and time information, In a password-protected door security system, and so on. I2C 16×2 LCD with Nodemcu ESP8266 Circuit Diagram:Īrduino 16×2 I2C LCD, Nodemcu 16×2 i2c LCD Code & Library- I have been using 16×2 LCD in different projects.
