Connect the Diplay with Arduino! Pins:

  • PIN DISPLAY | CONNECT TO ARDUINO
  • 1(VSS) | ARDUINO GND PIN
  • 2(VDD) | ARDUINO +5V PIN
  • 3(contrast) | RESISTOR -> ARDUINO GND PIN
  • 4(RS) | ARDUINO PIN 12
  • 5(R/W) | ARDUINO PIN 11
  • 6(Enable) | ARDUINO PIN 10
  • 7(DB0) | NO CONECTION
  • 8(DB1) | NO CONECTION
  • 9(DB2) | NO CONECTION
  • 10(DB3) | NO CONECTION
  • 11(DB4) | ARDUINO PIN 5
  • 12(DB5) | ARDUINO PIN 4
  • 13(DB6) | ARDUINO PIN 3
  • 14(DB7) | ARDUINO PIN 2
  • 15(BACKLED+)| ARDUINO PIN 13
  • 16(BACKLED-)| ARDUINO GND PIN

    I have been messing around with a couple of these displays. My experiense is that an Arduino pin is not able to suply enough power to drive the backlight. I drive it through a 2N3904 transistor and furthermore from a PWM pin. In this way I can regulate the brightnes. I also have a SparkFun frequency counter perhaps it's from there I have got the idea about the transistor driver. I have some ideas about expanding this with a voltage/current read out. ;-)
