Sometimes it may be necessary to use a display while making a hardware project, but the size and the type of the display may vary according to the application. In a previous project, we used a 0.96″ I2C OLED display, and in this project we will have an I2C 20×4 character display.
This tutorial will describe how to use 20 x 4 LCD display with Arduino to print a real-time clock and date.
