The project mainly aims in designing completely automated menu in restaurants with the help of touch screen sensor and a LCD to provide a user-friendly environment. There is no need of a person to take the order from the table. The menu will be displayed on the table and we can directly order the menu with the help of touch screen.   Touch screens provide fast access to any and all types of digital media, with no text-bound interface getting in the way. Faster input can mean better service. Using a touch interface can effectively increase operator accuracy, reduce training time, and improve overall operational efficiencies, a properly designed touch interface can improve each operator's accuracy. Touch screens are practical in automation, which has become even simpler with touch screen technology. Owners familiar with the icon system appreciate touch screens that make automation systems user friendly.   The system consists of a microcontroller, which is interfaced with the input and output modules, the controller acts as an intermediate medium between both of them. So the controller can be termed as a control unit. The input module is nothing but a touch screen sensor which provides the information like seat number and item to the microcontroller.  The output module is LCD to show the information, placed at ordering department. The controller also takes the responsibility to display the menu items on the LCD. At the receiving end the selected items will be displayed on LCD with user table number. Also, Buzzer based alerts will be given for every order. To perform this intelligent task, Microcontroller is loaded with an intelligent program written in embedded ‘C’ language.      

The main objectives of the project are:  

1. To order any food through simple touch.
2. Displaying the order information on LCD.
3. Buzzer based alerts for every order.

  This project provides exposure to the following technologies:  

1. Touch screen sensor.
2. Conversion of AC supply to DC supply.
3. Embedded C programming.
4. Design of PCB.
5. LCD interfacing.

  The major building blocks of this project are:  

1. Regulated power supply.
2. Touch screen.
3. LCD with driver.
4. Microcontroller
5. Reset
6. Buzzer with driver.
7. Crystal oscillator.
8. LED indicators.

      Software’s used:  

• PIC-C compiler for Embedded C programming.
• PIC kit 2 programmer for dumping code into Micro controller.
• Express SCH for Circuit design.
