A friend recently gave me a set of three (old) 16x2 LCD displays. (datasheet)
However, I'm having difficulty thinking through how to connect one to my Arduino. Particularly, each LCD has 14 (!) pins, of which 7 are denoted "data bus line" on the datasheet.
In the past, I've connected my Arduino to a LCD screen using serial connection, and I have an I2C LCD that I won at a competition recently (I've yet to use that one, though--I'm waiting on a specific type of jumper cable).
However, I've never used an LCD with this many pins, and certainly don't want to hog all the pins on my Arduino (Uno). So, my question is:
How do I communicate with this LCD, using my Arduino? (While keeping in mind that I want to do other things with the pins.)
