Product Description This is a basic 20 character by 4 line display. Black text on Green background. Utilizes the extremely common HD44780 parallel interface chipset (datasheet). Interface code is freely available. You will need ~11 general I/O pins to interface to this LCD screen.Includes LED backlight. Works on either 4 bit or 8 bit mode. For Arduino LCD library, Please refer to http://arduino.cc/en/Reference/LiquidCrystal?from=Tutorial.LCDLibrary. Connections to Arduino: 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 Parallel LCDs run off of +5V so you can just solder the Vcc (pin 2 in LCD)wire to 5V and the ground (pin 1 in LCD) wire to GND. * 10K resistor: * ends to +5V and ground * wiper to LCD VO pin (pin 3)
