This isn't technically a problem with the Arduino but more a request for help.
What is the name of the part that the proto shields slot into? I am building a small board at the moment and want to continue the neat idea of using 0.1 inch pin strip slotting into the thing called X.
I live in the UK and have tried looking for 0.1" female header at maplins, but with no success. What are they called and any ideas where I can get them?
