- Connect the other end to the GND pin on the Arduino.

2. Write the Arduino Code

Here is a basic example of Arduino code to read the state of a slot sensor:

const int sensorPin = 2;  // Change this to the pin you connected the sensor to

void setup() {
  pinMode(sensorPin, INPUT);
  Serial.begin(9600);
}

void loop() {
  int sensorState = digitalRead(sensorPin);
  Serial.println(sensorState);
  delay(100);  // Adjust delay as needed
}

3. Upload the Code

Connect your Arduino to your computer using a USB cable.
Open the Arduino IDE.
