An Arduino library for I²C LCD driver with sample code. This library provides simple API to display characters on the LCD. Include device name header file (PCA8561.h) to use those class libraries.

This project is a simple Arduino-based LCD tester that I built as a quick bench tool for checking 16x2 character LCD screens before using them in other projects. The tester runs a basic display ...

One of the limitations of the small 8 bit microcontrollers like the Atmel ATMega family adopted by the Arduino board, is the reduced number of I/O ports. Among the main advantages of these ...

LCDs are widely used in applications like token-display machines in s malls and supermarkets, order number displays in restaurants and café, and so on. The project presented here demonstrates the ...
