LiquidCrystal (7,6,5,4,3,2) / / (RS, E, D4, D5, D6, D7) So I have a conflict on pin 2 of Arduino. Do you have a solution for this?Any available I/O pin can be used for any of the LCD signals.
E 'can move the pin to read LCD?
This information is documented but well hidden on the Arduino site at: http://arduino.cc/en/Reference/LiquidCrystalConstructor.
Of course a simple comment in the example would also help to clear things up:
//LiquidCrystal lcd(RS, E, D4, D5, D6, D7);
LiquidCrystal lcd(7, 8, 9, 10, 11, 12); // put your pin numbers here
