The Brightness Control API allows developers to access
embedded devices and easily control brightness.
A watchdog timer (WDT) is a device that performs a specific
operation after a certain period of time if something goes
wrong and the system does not recover on its own. A watch-
dog timer can be programmed to perform a warm boot
(restarting the system) after a certain number of seconds.
The Hardware Monitor (HWM) API is a system health super-
vision API that inspects certain condition indexes, such as
fan speed, temperature, and voltage.
