This Arduino code controls a 16x2 LCD screen to display a counter that increases every second: #include <Adafruit_LiquidCrystal.h> - Imports the Adafruit LCD library to communicate with the LCD ...

In this tutorial we will see how to interface NodeMCU with 16x2 LCD without using I2C communication. Here we will interface 16x2 LCD using shift register SN74HC595.

In this tutorial we interface 16x2 LCD with ESP32, using only 2 pins, with the help of I2C communication. It reduces number of pins used by ESP32 so that more number of ESP32 pins remain free for ...

(address selection pads in the lcd backpack) Reference circuit diagram of an Arduino-compatible LCD backpack is shown below. What follows next is information on how to use one of these inexpensive ...

An LCD can be made to connect to a microcontroller using two wires with the aid of the I2C interface which includes pins for an SPI interface version for flexibility. The I2C LCD interface is used ...
