RF tx & Rx interfacing

Postby intimind » Fri Feb 22, 2013 4:25 pm

Hey,
i just wanna how to interface an RF 434mhz tx n rx to a microcontroller such as AT89C51.
i basically hav 4 leds on the tx side, so i need to transmit the detail as which one is high.
so the rx receiver jst turns on another corresponding LED.

Why not follow along with my article here:

I use a different microcontroller, but as long as your AT89C51 can output serial data @ 1200/2400 BPS it should work fine for you!
