Hello!
I am planning to make an Arduino UNO LCD shield using this 16x4 display (datasheet: https://focuslcds.com/product/16x4-stn- … axbsyly6wt) but I don’t know where to start?
Specifically, how do i connect it? Can I use I2C?
Thanks and I am looking forward to your help.
If you study the data sheets on the display product page (which is STRONGLY recommended for all projects!) you will discover that the display adheres to the ancient standard, HD44780 compatible.
There are tens of thousands of web pages that describe in great detail how to connect and use such a display.
