  • pin headers to solder to the LCD display pins
Added line 28:

Before wiring the LCD screen to your Arduino we suggest to solder a pin header strip to the 14 (or 16) pin count connector of the LCD screen, as you can see in the image above.\\

 /*
   LiquidCrystal Library - TextDirection
  
  Demonstrates the use a 16x2 LCD display.  The LiquidCrystal
  library works with all LCD displays that are compatible with the 
  Hitachi HD44780 driver. There are many of them out there, and you
  can usually tell them by the 16-pin interface.
  
  This sketch demonstrates how to use leftToRight() and rightToLeft()
  to move the cursor.
  
  The circuit:
  * LCD RS pin to digital pin 12
  * LCD Enable pin to digital pin 11
  * LCD D4 pin to digital pin 5
  * LCD D5 pin to digital pin 4
  * LCD D6 pin to digital pin 3
  * LCD D7 pin to digital pin 2
  * 10K resistor:
  * ends to +5V and ground
  * wiper to LCD VO pin (pin 3)
