Tutorial: How to Use 4-digit 7-segment Display with 0.36 Inch Digits

This 4-digit 7-segment display is ideal for displaying numbers and data in electronic projects such as counters, timers, or temperature monitors. It is suitable for beginner and intermediate makers who want to add clear visual feedback to their devices.

What you need

• Arduino Uno
• USB cable
• Test leads
• Batteries or power supply
• Driver 3461AS
• Power cable

Steps

1. Connect the display to the driver 3461AS following the pin mapping.
2. Connect the driver 3461AS to the Arduino.
3. Check the proper power supply of the display (check the datasheet).
4. Write the Arduino sketch to control the display.
5. Compile and upload the sketch to the Arduino.
6. Verify that the display shows the correct numbers.
7. Modify the sketch to update the displayed numbers.
8. Test the display with different data and configurations.

Example code

void setup() {
  Serial.begin(9600);
}

void loop() {
  displayNumber(1234);
  delay(1000);
}

void displayNumber(int number) {
  // Codice per visualizzare il numero sul display
}

Mini project

Create a step counter that displays the number of steps taken on a 4-digit display. Use a motion sensor or a button to count the steps and update the display in real time.

Common mistakes

• Connect the display to the driver with incorrect polarity.
• Do not power the display correctly.
• Write the sketch without considering the 3461AS driver.
• Do not update the numbers on the display correctly.

Recommended accessories

• PIR motion sensor
• Push button
• Pull-up resistors
• USB power supply cable
