Subject: [PIC] (VERY) new 16f84a programmer needs help!


Hello all

I've recently become interested in learning to program embedded chips, and 
with that in mind bought the starter kit featured in the link below:-

http://cgi.ebay.co.uk/Getting-Started-PIC-16F84-LED-PCB-kit-programmer_W0QQitemZ120281761643QQcmdZViewItem?hash=item120281761643&_trksid=p3286.m14.l1318

 I have built the circuit on a solderless bread board and I am as sure as I 
can be that it is all as per the diagram. I compiled the example source code 
using CCS PICC running in MPLAB and it created the .hex file repoting no 
errors (other than a warning because of the infinite loop). I then sent it 
to the 16f84a using icprog which seemd to work as expected.

When I power the circuit nothing happens. If I disconect pin 5 (Vss) the LED 
lights up but doesnt blink.

I'm sure I am missing something very simple but as I said, I am a complete 
novice with both programming and electronics so it it very tough to work out 
which part of the process I've done wrong.


Thanks in advance
