  void setup()
  {
  lcd.init();
  lcd.backlight();
  lcd.setCursor(0, 0);
  lcd.print("b2cqshop");
  lcd.setCursor(0, 1);
  lcd.print("Voltage: ");
  lcd.setCursor(13, 1);
  lcd.print("V");
  }
  void loop()
  {
  int val;
  float temp;
  val=analogRead(0);
  temp=val/4.092;
  val=(int)temp;//
  lcd.setCursor(9, 1);
  lcd.print(0x30+val/100,BYTE);
  lcd.print(0x30+(val%100)/10,BYTE);
  lcd.print('.');
  lcd.print(0x30+val%10,BYTE);
  delay(100);
