  1. Connect the ultrasonic sensors:

    • Ultrasonic Sensor 1:
      • VCC to Arduino 5V
      • Trig to Arduino Digital Pin 2
      • Echo to Arduino Digital Pin 3
      • GND to Arduino GND
    • Ultrasonic Sensor 2 (similar connections as above):
      • VCC to Arduino 5V
      • Trig to Arduino Digital Pin 4
      • Echo to Arduino Digital Pin 5
      • GND to Arduino GND

  2. Connect the motion sensors:

    • Motion Sensor 1:
      • VCC to Arduino 5V
      • OUT to Arduino Digital Pin 6
      • GND to Arduino GND
    • Motion Sensor 2 (similar connections as above):
      • VCC to Arduino 5V
      • OUT to Arduino Digital Pin 7
      • GND to Arduino GND

  3. Connect the buzzer and vibration motor:

    • Connect the positive (red) wire of the buzzer to a digital pin (e.g., Digital Pin 8).
    • Connect the negative (black) wire of the buzzer to a GND pin.
    • Connect the vibration motor to a digital pin (e.g., Digital Pin 9) for control. Ensure you have a suitable power source for the motor.
