Demonstrate that the buzzing of the door when the user comes late (Part 2)
We used a Magnetic Reed Switch to demonstrate the buzzer mechanism of a door.
The switch was conected with an Arduino board and the circuit was connected to a Laptop for mobility.
The magnet was attached to the opening part of the door and the switch was connected to the fixed part.
When the user entered the door late, the buzzer detected that the time of entry has passed.
The conncetion between the switch and magnet on the door has to be maintained in order to prevent the buzzer from ringing.
To add make the camera functioning.
To make the form of the LED clock.
To use ThingSpeak and push data.
