Yes I want to buy a spool of wire, but my question was what type of wire would be best? Does it matter? Some one in an earlier post replied that I could consider using copper wire .... which would suggest that it does matter. When I know what I want to buy, yes I will Google it .... but at the moment I'm just trying to get advice on what I need 
So ....
The options appear to be single core wire (similar to jumper wires) or copper wire (not sure if this is stranded or single core). Advice would be greatly appreciated.
Thanks
