Hi, I bought the Arduino IO expansion shield (https://images-na.ssl-images-amazon.com/images/I/91zgHMGyEiL._SX425_.jpg) but I couldn't see any articles or videos about its use, neither in English nor Turkish. For example, how do I connect my lcd screen to the lcd parallel section? How do I check with code? For example I have the port on the sd card reader but how do I use it. So what's the pin number?
