Introduction:
In this article I will explain about LCD display connection and we will see how to connect it with the
Arduino Mega 2560.
Parts Of Lists:
- Arduino Mega 2560
- LCD Display
- Bread Board
- Potentiometer
- HookUp Wires
LCD Display:
- LCD display is a flat panel display.
- It does not emit light directly.
- It will display the arbitrary images or fixed images with less information.
Connection:
Step 1: Connection from LCD To Arduino Mega 2560,
Figure 1: LCD Display
- Fix the LCD display from 16 to 02 in the BreadBoard.
- The 16 from the LCD can be connected to the Gnd.
- The 15 from the LCD can be connected to the Vcc.
- The 14 from the LCD can be connected to the Digital pin 07.
- The 13 from the LCD can be connected to the Digital pin 08.
- The 12 from the LCD can be connected to the Digital pin 09.
- The 11 from the LCD can be connected to the Digital pin 10.
- The 01 from the LCD can be connected to the Gnd.
- The 02 from the LCD can be connected to the Vcc.
- The 03 from the LCD can be connected to the potentiometer of centre pin.
- The 04 from the LCD can be connected to the Digital pin 11.
- The 05 from the LCD can be connected to the Gnd.
- The 06 from the LCD can be connected to the Digital pin 12.
Step 2: Connection from Potentiometer to ArduinoMega2560,
Figure 2: Potentiometer
- Take the first pin connected to Gnd of the ArduinoMega2560.
- Take the second pin connected to 3 pin of the ArduinoMega2560.
- Take the third pin connected to the Vcc of the ArduinoMega2560.
Programming:- #include < LiquidCrystal.h > // Includes the library code
- LiquidCrystal lcd(07, 08, 09, 10, 11, 12);
- void setup()
- {
- lcd.begin(16, 2);
- lcd.print("C# Corner");
- }
- void loop()
- {
- lcd.print(millis() / 1000);
- }
Before uploading the program add the Liquid Crystal library
Explanation:
- In this we can simply see the name or any content we type in the lcd.Printf statement.
- The LCD should be kept as 16 to 2.
- This is used in schools, buses, shopping malls, etc.
