Tutorial: How to Use Common Anode 0.56″ 4-Digit Display

This 7-segment digital display is perfect for creating counters or displaying numerical data in Arduino projects. Ideal for beginners and makers who want to add a visual element to their devices.

What you need

• Arduino Uno
• USB Type B Cable
• Test Connection (jumpers)
• Battery or External Power

Steps

1. Connect the display to the Arduino microcontroller following the pinout table in the datasheet. Check the specifications in the datasheet.
2. Install the LiquidCrystal library in Arduino IDE.
3. Write a simple sketch to test the installation: example code available in the ‘Code’ section.
4. Program the display to show numbers and characters. Use functions like print() and write(). Check the datasheet for segment combinations.
5. Customize the sketch to fit your specific project.

Example code

/*
#include <LiquidCrystal.h>

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup() {
  lcd.begin(16, 2);
  lcd.print("Benvenuto!");
}

void loop() {}
*/

Mini project

Create a timer that shows seconds and minutes. Connect the display to an Arduino timer to display the time progression.

Common mistakes

• Connect the pins incorrectly, always check the datasheet for correct connections.
• Do not load the necessary LiquidCrystal library.
• Use characters not supported by the display.
• Ignore the display’s polarity.

Recommended accessories

• Arduino Uno
• Test connection (jumpers)
• Batter or external power supply
• LiquidCrystal library

Frequently asked questions
