• 4-digit display
• 8 LED segments per digit
• SKU: ARD009366
• Price: 10.26 €

What it is for

The board is ideal for displaying numbers and letters on a 4-digit display. It can be used in Arduino projects for displaying information such as timers, counters, measured values from sensors, etc.

Tutorial: How to use 8 SEG LED Display Board

The 8 SEG LED Display Board is ideal for displaying numbers and letters on a 4-digit display. Useful for Arduino and beginner maker projects.

What you need

• Arduino or compatible
• Power cable
• 220 ohm resistor
• Check the datasheet

Steps

1. 1. Connect power to the display (VCC to 5V, GND to GND).
2. 2. Connect the resistor between VCC and Arduino pin D4.
3. 3. Connect the display to GND of the Arduino.
4. 4. Upload the code to Arduino.
5. 5. Check the numbers displayed.
6. 6. Replace D4 with another pin if necessary.
7. 7. Add code to display letters.
8. 8. Check current and power supply.

Example code

```
void setup() {
  pinMode(4, OUTPUT);
}

void loop() {
  digitalWrite(4, HIGH);
  delay(1000);
  digitalWrite(4, LOW);
  delay(1000);
}
```

Mini project

Create a simple timer by displaying seconds passed on a 4-digit display.

Common mistakes

• Forget to add a resistor (always use one with 220 ohm).
• Connect VCC to 3.3V instead of 5V.
• Forget to ground the display.
• Use an incorrect pin for the display.

Recommended accessories

• 4-digit 8-segment LED display
• 220 ohm resistor
• Arduino Uno
• Power cable

Frequently asked questions

The display doesn’t turn on?
Check the correct connection of VCC and GND, and the use of the resistor.

How can I display letters?
Use predefined display codes for letters (check the datasheet).

What is the maximum current?
Check the datasheet.

Can you use an Arduino Nano?
Yes, but it might require a different pin, check the datasheet.
