Getting a Serial LCD is much easier to work with both from a pin # and wiring perspective.
Thanks for the advice about the lcd , i found that a serial lcd is more expensive and i think the code is complicated comparatively to other lcd http://www.arduino.cc/en/Tutorial/LiquidCrystal ... But it's much easier at wiring you are right !
Anyway , it doesn't make any sense because if i completely remove the 7 digital pins of the LCD (if i was right at my last post) my pins will be 18 - 7 = 11 , but i need an lcd and i have only 3 digital pins left (UNO has 14) , so i have to go with MEGA.... i think...
