Added strike-through.

| Jul 7, 2015 at 21:17 | comment | added | Nick Gammon♦ | I don't see how that could be right. Why would the code care what pin is on the LCD logic chip? It needs to know what pin on the Arduino it uses for certain functions. | |
| Jul 7, 2015 at 9:09 | comment | added | radius | From my understanding, the pin used in the constructor, are the pin used by the logic chip on the LCD panel, not on the arduino. I don't have anything from the LCD connected on pin 2 and LCD works. If I changed '2' to another (not used) pin, the LCD no longer work. | |
