ACKNOWLEDGEMENT

We are thankful to Mrs. Manu Bharti for their Guidance to select this project. We are very thankful to BCET college. This project will help us a lot in practical training. It’s the time to implement theoretical knowledge to practical implementation.

Introduction and Working:

Smart Ordering Sysem is our MAJOR final Year Project. We planned lot of project but finally we decided to make this project.
In this project LCD will show few items. There will be touch display . When we Touch on realted item then it will send our information wireleslly from transmitter . Then order will be automatically placed . It will display on LCD attached on receiver side. Project is quite interesting. We are will finish asap to give final look. RF remote control which is built using HT12E and HT12D chips. The remote control is built using RF encoder chip HT12E that will generate different codes. These codes will be transmitted by 434 MHz RF transmitter. At the receiving side these codes will be received by 434 MHz RF receiver and decoded by RF decoder chip HT12D.
In this project we show that how we design a RF information transfer . In this project we use two RF module for wireless data transfer.In this project we use Arduino microcontroller as a main processor.. This controller is basically a 40 pin ic. In this project we use two sensor also.ROM of Arduino is 8k and ram is 256 byte. We are using 16*2 lcd in this project. Lcd is connected to port 0 which will display the no. On receiver side RF module will give signal to microcontroller. Microcontroller is decision maker here and informer to person on duty.It will give data to LCD , buzzer and LED’s. we will also use four LEDs for immediate action.
These sensor are connected to the port p3.4 and port p3.5

Pin no 40 is connected to the positive supply. In this project we provide a 5 volt dc power supply. This power supply is truly regulated power supply. Pin no 20 is connected to the negative supply. Here we supply a negative voltage on this pin. Crystal is connected to the pin no 18 and 19 of the microcontroller. Crystal provide a clock signal to run the vehicle and process all the internal requirement of the circuit. We use two sensor and these two sensor are connected to the p3.4 and p3.5 of the microcontroller.For the regulated power supply we use ic 7805 as a regulator to provide a fix 5 volt power supply.
In this project we will make a transmitter for RF data transmission. Pin no 1of RF tx module is ground . second is for data , third for VCC and fourth for antenna Transmitter
