problem in interfacing RF 433MHz module with pic16F877A.. kindly pls help….

[SUTARIYA HARSHAL]

hi guys.. i am making my final year project of automatic ambulance detection in ehich 

 

I put one simple RF 433 MHz toy car transmitter interface directly with Tx Pin of PIC 16F877A ..

 

and one receiver interfaced with Rx Pin of PIC 16F877A 

 

when i load program of transmitter and receiver in PIC , then nothing comes out at receiver..

 

I put some LED at PORT B of receiver PIC.

 

i have write simple program of transmitter and receiver which is given in mazidi for PIC 18.

 

i tried with low baud rate also..

 

and both pic and module is geven 5 v.

 

when i give RF Transmitter and Receiver module 9 v, then they work well. but the problem is that with giving 9 v to module my both PIC’s UART module has burned out..

 

and i can;t use it for UART. others program can waok well..

 

pls give me solution..

 

if any information required pls ask…
