arduino = serial.Serial(port='/dev/ttyUSB0', baudrate=9600, timeout=1)

Function to send data to the Arduino

def send_data(data): try: # Encode the string data to bytes and send it arduino.write(data.encode('utf-8')) print(f"Sent: {data}") except Exception as e: print(f"Error: {e}")

Main loop

if name == "main": while True: # Example data to send data_to_send = "Hello, Arduino!" send_data(data_to_send)

    # Wait for 1 second before sending the next message
    time.sleep(1)


**Note**: Ensure the Arduino is programmed to receive and process the data sent from the Jetson Orin NX.
