Re: remote car door help

Better option than IR or ultrasonic is 433MHz RF link ..
Here is an example:
4 CHANNEL AUTO ROLL RF REMOTE CONTROL RELAY BOARD

remote car door help

rws434 and tws 434 are easily available rf rx/tx pair, u need a decoder and encoder, now if encoder has 8 address pin and 4 data pin, u can use data pin as different channels and u can get 15/16 combination. if u need further help on this track feel free we will help u.
