RF Modules are popularly used in remote control system . In Quadcopter , Robot remote control , Industrial remote control, telemetry and remote sensing etc. Get more details here RF_Wiki
Basic Concepts:
RF module consists of Two Units Transmitter and Receiver. We will use two pic microcontrollers to create transmitter section and receiver section. In Transmitter section we will connect one pic18f2550 with Transmitter and this will transmit signal according to the commands. The Receiver section will be built with another pic18f2550 and receiver unit. This section will receive signal from transmitter unit and the receiver unit will send data to the microcontroller. Finally microcontroller will execute led switching according to instructions.
RF Transmitter :
RF Module ( Wireless Radio Frequency )Transmitter_Tx
RF Module ( Wireless Radio Frequency )Transmitter Pinout
RF Receiver :
RF Module ( Wireless Radio Frequency ) Receiver Rx
RF Module ( Wireless Radio Frequency ) Receiver Rx
I didn't use any decoder or encoder circuit and I've no practical experience of using encoder or decoder. Maybe for making something secured you need encoder or decoder I guess. Thank you.
Hi a question, Is necessary in this circuit ,use a crystal of 12 MHz ?,Can I use other crystal? for example 10 MHz,20 MHz or internal crystal of uC . :)
If you use my code I mean hex file then you need 12MHz clock. But if you build project using my code you just need to define crystal frequency as you want. THat's it.
The LED screens has always created its own impact in the indoor advertisements, the one classic example of the LED has been in the airports which uses the LED screen to display announcements, notices and alerts. LED display
Somebody Sometimes with visits your web journal consistently and prescribed it as far as I can tell to peruse also. The method for composing is fabulous furthermore the substance is first rate. Much obliged for that understanding you give the perusers! I can't envision concentrating sufficiently long to research; considerably less compose this sort of article. You've beaten yourself with this material. This is extraordinary substance. Amazing Web Facilitating
Hey Hello...
ReplyDeleteI want to ask one question regarding this RF based LED Switching project that you have provided for us..
I just want to know is it necessary or not to avoid encoder and decoder IC's in this project?
As per your circuit diagram you are not using that encoder and decoder IC's...
Please help me...
Thank You...

ReplyDeleteHa ha ha.......
DeleteThank you. I didn't know that much.
hi, please could you send the download link for the rf transmitter and receiver library for proteus. Thanks
ReplyDeleteNever mind thanks... seen it
DeleteIt's ok. You are welcome :)
