LCD display

I wanted to add other features to my project which is LCD display therefore I tried the Arduino LCD display tutorial. My target is to print out text message “kid, can you hear?” on the first row and Y=node or N=shook on the second row to ask the kid whether she/he can hear the sound produce by the buzzer.

LCD display is great way to display output from your arduino when it not connected to your computer. The common display used in arduino projects is 16×2 parallel LCD display which compatible with the Hitachi HD44780 driver. It can easily recognize with it 16 pin interface.

The parts list required;

1) 1x 16×2 parallel LCD display (compatible with Hitachi HD44780 driver)
2) 1x Arduino
3) 1x 10kΩ potentiometer
4) Jumper wire

Instruction of connecting the LCD to Arduino;

1) Connect all jumper wire as shown in diagram.(above)

2) Plug in 10kΩ potentiometer on breadboard. This potentiometer use for adjusting the contrast of the LCD character.

3) Plug in LCD display on breadboard

:: Below is the picture of my LCD circuit displaying  “kid, can you hear?” and Y=node or N=shook and also the program i've wrote.

# i might need to use bigger size of LCD since i need to display more texts.
