This project is an amelioration of a classical collectivity water fountain.
Here, the red LED represents the solenoid controlled by the Arduino.
The power tensions are ignored.
The concept is:
One fountain for 3 persons
When a person wants to drink, he puts his glass and press his button
he keeps his button pressed while his glass is not full
The main function of the project is to compute the time and the volume distributed to a person, and increment a counter variable of total volume.
On the photo, the 3 buttons at the top left corner are assigned to the 3 different persons.
This switch at the top mid is the detector of the glass presence.
