![]() ![]() Serial Monitor is extremely important for the programmer to know what’s going on, what the microcontroller is doing and whether the microcontroller is doing things as expected. The standard way for an Arduino to display measured data or to keep track of output is its Serial Monitor functionality. The purpose of this paper is to provide a beginner with the basics of connecting a LCD display to an Arduino via an i2C adapter: the 16-pin IIC/I2C/1602/2004 LCD adapter, also called ‘i2c expander’ This way of communication requires only two pins on the microcontroller bord: A4 and A5 By Floris Wouterlood – the Netherlands – July 4, 2017Īn easy solution to display data on a LCD display, especially when you are about to run out of pins on your Arduino is to use I2C mediated display.
