#120844 - IR proximity detector
I want to transmit RC codes from 89c2051 and recieve that on same chip.

RC codes are remote control codes.
so in this project transmission and reception are to be done by same chip.
so everyone is invited to present his view on this.

RC codes are used so that no other ir source can trigger false alarm
also using RC codes give more range in IR rx modules then a continous 38khz signal.

I am using modules similar to TSOP1738
similar modules from some companies don't even respond to continous 38khz they need some modulation.
