One step further than interfacing 16x2 LCD with Arduino.
Interfacing of 16x4 LCD plays by same rules as common 16x2 LCD. Same connections; same Arduino build in library code. Just change little bit of code as pointed to by this video. It is bigger LCD can display more data, more values and brings in more convenience.
