How to Use Arcade Button (white): Examples, Pinouts, and Specs

The Arcade Button (White) is a push-button switch commonly used in arcade machines. It features a durable and responsive mechanism designed for frequent user input. This button is ideal for various applications, including gaming consoles, DIY electronics projects, and interactive displays.

The Arcade Button typically has two terminals:

1. Mounting the Button:

   • Drill a 24 mm hole in your panel or enclosure.
   • Insert the button into the hole and secure it using the provided nut.

2. Wiring the Button:

   • Connect the NO terminal to the input pin of your microcontroller or circuit.
   • Connect the COM terminal to the ground (GND) of your circuit.

Below is an example of how to connect the Arcade Button to an Arduino UNO:

Arcade Button (White)
  +-------------------+
  |                   |
  |  NO  ----> Pin 2  |
  |  COM ----> GND    |
  |                   |
  +-------------------+

// Arcade Button Example with Arduino UNO
// This code reads the state of the arcade button and turns on an LED when
// the button is pressed.

const int buttonPin = 2;  // Pin connected to NO terminal of the button
const int ledPin = 13;    // Pin connected to an LED

void setup() {
  pinMode(buttonPin, INPUT_PULLUP);  // Set button pin as input with internal pull-up
  pinMode(ledPin, OUTPUT);           // Set LED pin as output
}

void loop() {
  int buttonState = digitalRead(buttonPin);  // Read the state of the button

  if (buttonState == LOW) {  // Button is pressed
    digitalWrite(ledPin, HIGH);  // Turn on the LED
  } else {
    digitalWrite(ledPin, LOW);   // Turn off the LED
  }
}

• Debouncing: Mechanical buttons can produce noise or "bounce" when pressed. Consider implementing software debouncing in your code to ensure reliable button presses.
• Current Rating: Ensure that the current passing through the button does not exceed its rated 3A to prevent damage.
• Mounting: Secure the button firmly to avoid any movement during operation, which could affect performance.

1. Button Not Responding:

   • Solution: Check the wiring connections. Ensure that the NO terminal is connected to the correct input pin and the COM terminal is connected to GND.

2. Button Bouncing:

   • Solution: Implement software debouncing in your code. You can use a simple delay or a more sophisticated debouncing algorithm.

3. Button Sticking:

   • Solution: Ensure that the button is not physically obstructed. Clean the button mechanism if necessary.

Q1: Can I use the Arcade Button with other microcontrollers?

• Yes, the Arcade Button can be used with any microcontroller that can read digital inputs, such as the Raspberry Pi, ESP8266, or ESP32.

Q2: How do I implement software debouncing?

• You can use a simple delay in your code to debounce the button. For example:

if (buttonState == LOW) {
  delay(50);  // Wait for 50 milliseconds
  if (digitalRead(buttonPin) == LOW) {
    // Button press is confirmed
  }
}

Q3: Can I use the Arcade Button for high-voltage applications?

• The Arcade Button is rated for 3A @ 125V AC. Ensure that your application does not exceed these ratings to prevent damage.

By following this documentation, you should be able to effectively integrate the Arcade Button (White) into your projects. Happy building!
