Pin definition:

Module debugging:
 
 The LCD Keypad Shield plugged into the Arduino controller, then you need to download LCD4Bit_mod.h (Right Save As) library file to arduino-0015 hardware libraries, followed by a test program compiled below and then download to the Arduino, the initial use LCD Keypad Shield, the first observation LCD has no display character, if the character does not appear likely that the contrast is not correct, you can use the screwdriver adjust RP1 (clockwise rotation), characters can be transferred to emerge clearly.

Professional anti-static packaging



Test renderings:

  GP2D12 ranging code: 

#include

LCD4Bit_mod lcd = LCD4Bit_mod(2);

char GP2D12;
char a,b;
char str1[]="Renge:";
char str2[]="   Renge Over   ";
char str3[]="cm";

void setup()
{
  lcd.init();
  lcd.clear();
  lcd.printIn("GP2D12 testing..."); 
}

void loop()
{
      GP2D12=read_gp2d12_range(1);
      if(GP2D12>80||GP2D12<10)
        {
          lcd.cursorTo(2,0); 
          lcd.printIn(str2);     
        }
      else
        {
          a=0x30+GP2D12/10;
          b=0x30+GP2D12%10;          
          lcd.cursorTo(2, 3); 
          lcd.printIn(str1);    
          lcd.print(a);    
          lcd.print(b);
          lcd.printIn(str3);                    
        }    
    delay(50);
}

float read_gp2d12_range(byte pin)
{
 int tmp;
 tmp = analogRead(pin);
 if (tmp < 3)return -1; 
 return (6787.0 /((float)tmp - 3.0)) - 4.0;
}
