Demonstrate that the buzzing of the door when the user comes late (Part 1)
We initially used a Piezo buzzer to demonstrate the buzzer mechanism of the door.
The Piezo buzzer was conected with an Arduino board and the circuit was powered up.
It was azzumed that the Piezo buzzer will buz if there is an interference in the path of the infrared ray it reflects.
The Piezo buzzer requires a stability of the environment surrounding it in order to identify disrupancies in future.
However, due to the lack of environmental stability in the environment of installment, the use of Piezo Buzzer was eleminated.
To use a Magnetic Reed Switch instead of a Piezo buzzer for accurate results.
