Hello Ceans,

Here i want to share one small project that i have made for RF communication.
I am going to show off the Some Pics i have taken for this project and there is also one video.

For the all technical detail you can check out my Another Topic on the same project:- http://www.crazyengineers.com/forum/...ing-rfm70.html :rolleyes:

I have used General Purpose Board as there are very few components required.

Microcontroller i have used :- ATMEL- AT89S52.
Programmer for ATMEL:- TOPWIN Universal Programmer.
RF Module:- RFM70 from HOPE RF.
Communication between Microcontrolller and RF module:- SPI

Assembling the Power Supply section for 7805- 5 Volt Regulator

With PhoneJack, Crystal, Power Supply and other Indication LED.

Solder side

Interfaced with RF Module:- RFM70 and its now ready to use.

RFM70 Soldering, This is bit tricky as the pitch is very small. ;)

Back Side of GPB with 3.3 Vold SMD Regulator, Now i am going to Run the project. :cool:

Topwin Universal Programmer for loading the Code into AT89C52

And Finally, The Working Board

Guys in this project i have made one pair of Transmitter and Receiver and used Two LED as a indication of transmission and reception so here i am uploading a video that shows the LED blinking as per the transmission and reception.

Blue LED is Blinking when i am sending the data and the same way when receiver receives the data it will compare it and if the data received is OK then it will blink the Green LED.
