Take digital port: PIN4 (DB4), 5 (DB5), 6 (DB6), 7 (DB7), 8 (RS), 9 (E), 10 (backlight control), analog key port A0 . (LCD color is not specified, the random delivery.) used in conjunction with Roboduino:

Module debug: Plugged into the LCD Keypad Shield Arduino controller, and then need to download LCD4Bit_mod.h (Save as) library file to arduino-0015 \ hardware \ libraries in, then compile the following test program will be downloaded to a Arduino, the first Use LCD Keypad Shield, the first observation of the character LCD has no display, if the character does not show that the contrast may be incorrect, you can use a flathead screwdriver adjust RP1 (clockwise rotation), the character can be transferred to appear clearly. Professional anti-static packaging
