* The Door class.
|
|
*
|
|
* This class exists as a singleton as only one door and hence one object may exist.
|
|
* Available via the get() method.
|
|
*
|
|
* This class is responsible for opening and closing the door by sending
|
|
* the heartbeat to the AVR board via Raspberry Pi GPIOs
|
|
*
|
|
* Whenever the unlock() is called, this class also sends a 0x55 resp. 0xaa
|
|
* to the AVR in order to klacker the schnapper.
