  5. Outline of Approach User Interface(Screen, Bill Acceptor) EEPROM Motorola 68000 Microprocessor Non-Volatile RAM Electronically Controllable Valves (solenoids)

  6. L.U.S.H General Configuration

  7. User Interface • LCD screen to view drink availability and selections • Numeric key pad to scroll through options and enter pin numbers • Bill acceptor to pay for drinks

  8. Software • Drink Database • Liquor/Mixer Availability • Liquor/Mixer Type with Valve Address • Payment Verifier

  9. Valves • Use a series of solenoid valves to control the flow of liquid • Solenoids will be controlled by micro controller

  10. Two Solenoid System • Attached to the bottle is a 1 oz tubing • Each end will have a solenoid • Closing the bottom solenoid and opening the top one will fill the 1oz tube • Closing the top one and opening the bottom will dispense the 1oz liquid Top Valve 1 oz Tubing Bottom Valve

  11. Bill Acceptor • Accepts one dollar bills to credit towards drinks • Sends signal to microprocessor

  12. Division of Labor • Programming: Andrew, Heather, and Mike • Construction: Taymoor and Pezh • Testing: Taymoor, Heather, and Pezh • User Manual: Andrew and Mike

  13. Schedule

  14. Risks • Placing a bottle in the wrong receptacle • Valves will allow variable volumes due to changing pressure in the bottle • Severe hangover

  15. Contingencies • Use variables for the bottle location in the software that can be updated according to content • Replace valves with pumps • Chaser pill dispenser
