Im very much happy for your reply guys. U know im just a baby to this technology. Anyhow, the things that id like to do is as follows:
1. Using PC, connect a single PIC-based RF/Ultrasonic module (PIC16F84/PIC16F877) to the RS232 interface of the PC. ( But as of now i really dont know how to do it!)
2. Another module PIC-Based RF/Ultrasonic module (not connected to the PC)[external]. This will beam towards [1] module. From their if possible, i will simulate it from the PC that there is an interaction or communication between the two PIC-based module.
I hope you can englighted me on what to do. Where should I start and how?
In our country, which is thirld world country we only PIC16F84 and PIC16F877.
