In this project we want to send encrypted data. RF Transmitter which is built using HT12E. 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.
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.
