Example code

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
void setup() {
  lcd.begin(16, 2);
  lcd.print("Hello, World!");
}
void loop() {
}

Mini project

Create a simple thermometer that displays the external temperature on the digital display.

Common mistakes

• Connect the display pins incorrectly.
• Use an inappropriate value for pull-up resistors.
• Do not configure the display correctly in the library.
