What it is for

The six-pin MSS-22D18 buttons are useful for projects requiring simple human-machine interactions. They are ideal for creating a presence counter or other devices that need to detect user input through a button.

Tutorial: How to use 4 Pieces MSS-22D18

These six-pin buttons are ideal for projects requiring simple human-machine interactions. Useful for beginners and intermediates.

What you need

• 4 pieces MSS-22D18
• Arduino
• Pull-up resistor (10kΩ)
• Power cable

Steps

1. 1. Check the datasheet for specifications and dimensions.
2. 2. Mount the buttons on a PCB or protoboard.
3. 3. Connect the buttons to an Arduino pin using pull-up resistors.
4. 4. Run the provided Arduino code.
5. 5. Test the buttons to ensure they work correctly.
6. 6. Add a display or LED to show the state of the buttons.
7. 7. Check the contact stability.
8. 8. Install the product in a final project.

Example code

```
int buttonPin = 2;
int buttonState;

void setup() {
  pinMode(buttonPin, INPUT_PULLUP);
}

void loop() {
  buttonState = digitalRead(buttonPin);
  if (buttonState == LOW) {
    Serial.println("Pulsante premuto");
  }
}
```

Mini project

Create a simple presence counter using MSS-22D18 buttons as switches.

Common mistakes

• Connect the buttons without pull-up resistors.
• Use pins different from those indicated in the code.
• Omit the button testing.
• Do not use a PCB or protoboard.

Recommended accessories

• Arduino Uno
• 10kΩ Resistors
• 16×2 LCD Display

Frequently asked questions

How can I test the buttons?
Connect the buttons and the pull-up resistor to an Arduino pin and run the provided code.

Which pins should I use for the buttons?
Use the digital pins of Arduino.

Can I use an Arduino Mini?
Yes, but make sure the pins are compatible.

What to do if the buttons don’t work?
Check the connection and pull-up. Check the Arduino code.
