Tutorial: How to Use Momentary Waterproof Button Kit

These buttons are ideal for projects that require secure and waterproof user interfaces. Useful for beginners and intermediates.

What you need

• Arduino or compatible
• Test lead
• Multimeter
• Pliers

Steps

1. 1. Check that the buttons are waterproof.
2. 2. Prepare the Arduino and connect the buttons to pins 2 and 3.
3. 3. Check the datasheet for the maximum current.
4. 4. Load the example code.
5. 5. Test the buttons to make sure they work.
6. 6. Connect the buttons to the final circuit.
7. 7. Verify the stability of the contacts.
8. 8. Install the buttons in the final project.

Example code

```
int buttonPin = 2;
int ledPin = 13;

void setup() {
  pinMode(buttonPin, INPUT);
  pinMode(ledPin, OUTPUT);
}

void loop() {
  if (digitalRead(buttonPin) == HIGH) {
    digitalWrite(ledPin, HIGH);
  } else {
    digitalWrite(ledPin, LOW);
  }
}
```

Mini project

Create a simple alarm system with a button and an LED.

Common mistakes

• Connect the buttons to the wrong pins.
• Omit the contact test.
• Do not check the maximum current.
