Is the bar open or closed? - An Arduino based hardware button to inform members of Jumpteam Scheveningen* if the canteen is open or closed. The open / close status is visible on the club's website.

Hardware:
-Three buttons with light indicator; open, close and reset.
-Arduino Ethernet board.
-Adafruit OLED-display.
-The case is a converted radio I found under a thick layer of dust in my bedroom.

Besides changing the open-status the software also checks if the network connections still exists.

*Jumpteam Scheveningen is a surf sports club on the beach of Scheveningen (The Hague, The Netherlands).
