This Arduino sketch demonstrates how to use an I2C-enabled LCD display with an Arduino board. The LiquidCrystal_I2C library is used to control the LCD, and the sketch also includes a function to ...

This is an Arduino library for HD44780 LCD display, operated in 4 bit mode over I2C bus with 8-bit I/O expander PCF8574 This project is a C++-based smart lock system developed on an ESP32 board. It ...

We all know how the free pins microcontrollers are precious. The use of an LCD display in our projects is often unavoidable. In the best case the cost is at least six pin and you'll understand, ...

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 ...
