New bassystem V2.0

The bar system has a few different components:

  • a touch screen that is handled by an arduino that forwards clicks to USB.
  • an electronic key reader that is also read by the arduino and after checking also forwarded to USB.
  • a bar-code scanner that also is forwarded to the same USB port.
  • an ordering screen where multiple products can de ordered at once and a confirmation screen with the financial information.
  • a screen where the user can deposit new money to his account.
  • an historic overview screen that allows the user to page through the months and shows per day the financial changes.
  • a special bar-attendant mode where a single person is allowed to handle orders for multiple members.
  • a admin screen where all product details are shown.

BAR tronics

Electronics to read the serial touchscreen, the bar code scanner (also serial) and iButton reader.
