Relay relay(relayPin);
void setup() {
  pinMode(emergencyStopPin, INPUT_PULLUP);
}
void loop() {
  if (digitalRead(emergencyStopPin) == LOW) {
    // Emergency stop button pressed, turn off relay
    relay.off();
    Serial.println("Emergency stop activated!");
    // Add your additional logic here
  }
}
```
