ATMEL AT89S52 + RFM70 for Wireless Data Transmission !

I have interfaced RFM70 a 2.4GHz RF Module with ATMEL's AT89S52 microcontroller and used it for wireless communication. 

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

Here is the Pictures of that project.

Step 1: Assembling Power Supply

First step is to assemble the components for the Power supply, Here i have used 7805.

Step 2: Board With PhoneJack,Crystal and LEDs

Here i have assembled Power Supply, Crystal and other Indication LEDs on board.

Step 3: Wiring Side !

Solder Side of the General Purpose Board.

Step 4: Interfacing With RFM70

Here is the interfacing with RFM70 Module.

Step 5: Complete Board

Here is the Complete Board, And Ready to Use. :)

Step 6: And Finally Running Project

Here is the Snap of the running Project. ;)

Step 7: Video for You

Here is the Video for you guys,

There is pair of transmitter and receiver. BLUE LED blinks everytime data is being transmitted and at receiver side the GREEN LED blinks if the receiver receives the data.

I don't know that how to Embed the Video. :(

my project is about dtmf based speed control of dc motor...i am using at89s52 for pwm generation..can u plz provide the program..

[gsandhu2]

I’m working on a project which is about making a rescue
robot . I have struggling with it for 4 months and now all the mechanical works
had been done . but I’m facing difficulty in make the robot to work with rf
module can u plzz help me…

I want make transmitter and receiver that can control the
motion…I mean that receiver should have control 8 dc gear motor and each dc motor
should have a forward and backward botton to control the motion ……can u kindly
help me with this project ….if u can make the circuit board diagram for the PCB
….or any other suggestion plz reply me. or can mail me at "[e-mail]"

I have been searching for this. thanks! Could you please upload the schematic please.
or mail me the reference to [e-mail]

[Vicharshunya]

Hi Buddy, Sorry But I do not have prepared schematic for that. you can see RFM70 datasheet they have provided reference design there.

[ybautista1]

Can you share to us the copy of schematic diagram of that circuit.,thank you!

[Vicharshunya]

I have not prepared Schematics for that but I can send you reference design which you can use. Its easy.

[pmounica]

can i do the same concept with PIC micocontroller
give me some suggestions

[Vicharshunya]

Yes, You can do the same with any Microcontroller.

This is a great Instructable, but you need to add a main image of the final project to the intro step. Please do that, and leave me a message when you have so that we can publish your work.

Thanks!
