Tutorial: How to Use 3 Pieces DS-02 Code Button

The DS-02 button is ideal for projects that require interactions as they develop. Useful for beginners and intermediates, it serves to control user input.

What you need

• 3 pieces DS-02 Code Button
• Arduino
• Power cable
• Multimeter (optional)

Steps

1. 1. Installation: Assemble the pieces on the circuit or protoboard.
2. 2. Connection: Connect the button pins to your Arduino. GND to GND, VCC to 5V, pull-up to a digital pin.
3. 3. Coding: Check the datasheet for the pull-up specifications.
4. 4. Test: Power on the Arduino and verify that the button works correctly.
5. 5. Code: Add code to check the state of the button.
6. 6. Debug: Use a multimeter to verify the correct polarity.
7. 7. Assembly: Mount the button on the final project.
8. 8. Test: Verify functionality in real-world conditions.

Example code

```
int pulsante = 2;
void setup() {}
void loop() {
  if (digitalRead(pulsante) == HIGH) {
    Serial.println("Pulsante premuto");
  }
}
```

Mini project

Create a simple button pressure counter in 30 minutes.

Common mistakes

• Connect the pull-up to VCC instead of a digital pin.
• Omit checking the pull-up on the datasheet.
• Forget to test the button before final assembly.
• Do not use a multimeter to verify the correct polarity.

Recommended accessories

• Arduino Uno
• USB power cable
• Multimeter
• Protoboard

Frequently asked questions

How to connect correctly to the pull-up?
Connect the pull-up to a digital pin and not to VCC.

Which pins to use for the button?
Use a digital pin, for example 2, 3, 4, or 5.

Does the button work with Arduino Mini?
Yes, but make sure the pin used supports digital.
