2. Purpose Make an intelligent restaurant with a digital menu and pay machine. That will help the customers to depend on themselves and to replace the waiter by this technique.

3. Flowchart

4. Introduction Our Idea Digital Menu Smart Pay Machine Smart Screen

5. Digital Menu Program the microcontroller C++ Program

6. Components LCD Display 8051 microcontroller- AT89C51 Keypad 4x4 33pf Capacitors 10pF Capacitor 8.2K Resistor 11.0592MHz Crystal

7. Data Sheet (Microcontroller & Keypad)

8. Data Sheet for the LCD

9. Circuit

11. Pay Machine We need pay machine to allow customer to pay. Pay Machine have 2 section: 1. circuit to count the coins 2.Add program to connect the senor to the microcontroller to display the counting in the LCD

12. Components Count the coins Optical sensor 2- resistor (240Ω) 5Voltage Wire Jumper

13. Optical sensor The HOA2001 consists of an infrared emitting diode facing an Opto Schmitt detector encased in a black thermoplastic housing. The buffer logic provides a high output when the optical path is clear, and a low output when the path is interrupted.
