This is my second project.To make this you need three things
1. RFID module
2. IC HT12D and IC HT 12E
3.Atmega8 or any other Micro-controller
I’ve finally got a nice and cheap RFID . It cost me around Rs. 450. In order to use this you need to have HT12D and HT12E. HT12D is 1:4 line decoder IC and HT12E is an 4:1 line encoder IC. RFID consist of two chips transmitter and receiver, with the transmitter connect HT12E and with the receiver connect HT12D. You can find the connection in the data sheet of these IC’s . Next you need to make a remote ,which is very simple if you use push buttons.Program your micro-controller according to the data you send and connect your car to it.
Some useful data sheets:
1. HT12E
2. HT12D
I hope you find this project intresting . If you need any help feel free to contact me.
