Hello does anyone know how can i send data from Pic to Pc using USB?
I am assuming that you PIC does not have an embedded USB.
You will have to use (you can try ebay) a SERIAL <--> USB converter. Connect SERIAL side to the PIC and the USB side to the PC (needs drivers if using Windows).
I've used this solution a lot of times.
The solution given by Fernando Machado, is very much feasible.
Your PIC Micocontroller and your computer/laptop can be made to communicate with each other using the USART communication protocal.
I have already made a tutorial (link below) which explains how this could be done
