HD44780 16 by 2 LCD DISPLAY…

Recently I was engaged in a simple but interesting little project i.e using 16 by 2 LCD DISPLAY through different microcontrollers like PIC16F877A and ATMEGA328(Arduino uno).


Here are some hints and the code which might interest some of beginners:

1.Make connections as follows:

  • 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.
  • LCD VSS pin to ground.
  • LCD VCC pin to +5V.
  • LCD VCE pin to a 10K potentiometer(varying this resistance will vary the display).
  • LCD V+ pin to +5V or you can use a 100K potentiometer to vary the background led intensity)
  • LCD V- pin to ground.

2. Use the code(https://skydrive.live.com/redir?resid=B8FF27E1026C49ED!245&authkey=!ADc69b5b17QKIjw) or create your own and enjoy!
