Tutorial: How to Use the 12x12mm Push Button Module

This push button module is ideal for projects requiring simple user interactions. Useful for beginners and intermediates.

What you need

• 12x12mm Push Button Module
• Arduino
• DuPont Connectors Cable
• Pull-up Resistor (10kΩ)

Steps

1. 1. Connect the push button module to pin D2 of Arduino with a Dupont cable.
2. 2. Connect the pull-up resistor (10kΩ) between the VCC pin and the input pin of the button.
3. 3. Connect the GND pin of the button to the GND of Arduino.
4. 4. Use the following code to control the state of the button.
5. 5. Check the datasheet for further details.
6. 6. Upload the code to Arduino.
7. 7. The on-board LED should light up when the button is pressed.
8. 8. Verify the functionality of the button.

Example code

```cpp
int pulsante = 2;
void setup() {
  pinMode(pulsante, INPUT);
  Serial.begin(9600);
}

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

Mini project

Create a simple pulse counter with a 7-segment display.

Common mistakes

• Omitting the pull-up resistor can cause stability issues.
• Connecting the output pin of the button directly to VCC without a resistor can damage the Arduino.
• The output pin of the button must be configured as INPUT.
• Always verify the correct polarity of the connections.

Recommended accessories

• 7-segment display
• Dupont cable
• Arduino UNO
• LED
