Sample Project:

Circuit:

Library: No external library required.

Code:

const int digitalPin = 2; // Digital input pin for the keypad

void setup() {
  Serial.begin(9600); // Initialize serial communication
  pinMode(digitalPin, INPUT); // Set the digital pin as input
}

void loop() {
  int buttonState = digitalRead(digitalPin); // Read the digital value from the keypad

  // Check if a key is pressed
  if (buttonState == HIGH) {
    Serial.println("Key pressed");
    delay(500); // Avoid rapid multiple readings
  }
}
