Introduction

In this  project we will  make one transmitter and RF receiver. From transmitter we will send the roll no . of student. On receiver side we will mark the attendance. 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. These codes are fed to 89C51 to take a controlling action on moon walker. We will use 16*2 LCD display.

For the regulated power supply we use ic 7805 as a regulator to provide a fix 5 volt power supply.

. Here we use pc 817 ( 4 pin opto coupler) to interface the micro controller with  the motor circuit.

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
