In reply to Taolo. You should include the header file stdio.h to use sprintf(). By the way thanks for asking this question, I have included this information in the article also.

Hi. I cannot use the sprintf function. I get an error in building the code. How should be included, the sprintf function?

In reply to Guest579. I am not sure about this particular LCD. But you can use any LCD which uses a controller compatible with HD44780. So first check whether this LCD controller is HD44780 compatible. If not you might need to make minor changes as per the specifications of that particular controller. In my experience, most of these kinds of LCD's controller are compatible to HD44780.

Hello, Ive ordered the pic you re using, but my lcd is a qapass 16×2 lcd ( from the elegoo mega 2560 kit). From your experience, do you know if the lcd controller is compatible or do i need to buy a new lcd…where did you buy yours from? Does it exist on amazon or ebay? If yes could you provide a link?
Thank you!!!
