liudr:
I was just thinking about basic breadboarding. Maybe next time I will bring out that header. What do people use that header for? Programming, debugging, what else?
I've personally never used it for anything 
Oh and the 5V and ground lines didn't fit into the sides on my breadboard (obviously different spacing but I used sockets so they come out the top). I hadn't realised that that's what the connections were meant to do until I looked at your pic again
