Problem for test threads:

battery_test_thread = threading.Thread(target=battery_test, args=(), daemon=True)
water_valve_test_thread = threading.Thread(target=water_valve_test, args=(), daemon=True)

Problem for test threads: ```python battery_test_thread = threading.Thread(target=battery_test, args=(), daemon=True) water_valve_test_thread = threading.Thread(target=water_valve_test, args=(), daemon=True) ```
