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.
Flowchart
Introduction
• Our Idea• Digital Menu• Smart Pay Machine• Smart Screen
Digital Menu
• Program the microcontroller• C++ Program
Components
• LCD Display• 8051 microcontroller- AT89C51• Keypad 4x4• 33pf Capacitors• 10pF Capacitor• 8.2K Resistor• 11.0592MHz Crystal

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
ComponentsCount the coins
• Optical sensor • 2- resistor (240Ω)• 5Voltage • Wire Jumper
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.

Build the Circuit
•It is help to get the order faster than the normal one
•Save money ( because we do not have any waiters or accountant )
•keep pace with the technological area
•We know that we are in the era of speed
