I'm very new to hardware and arduino.
It seems to me that the protoshield could be more useful if there were built-in pins for the switch and the two leds.
Forgive me if I get the terms wrong.
I'm thinking about adding a male header with three pins. One could be connected to a digital input pin to read the button. The other two could be connected to digital output pins to light the leds.
So I should be able to run a wire from the header to the holes marked led 1 and led 2 ... each of these leds appears to have a current limiting resistor already. I think I can see how power can run to that hole, follow the trace to and through the resistor, and then into the led itself. I know its on the schematic, but I have a hard time relating that to the board (everything's so tiny).
From what I've read, I need a pull up resistor to use the switch ... I'm a bit confused, but I think this means that I should connect the header to +5V via the resistor, but also connect the same header to the switch. I have to assume this would be to the hole marked "+". End result: the input pin will read HIGH until the button is pressed.
To be honest, this is like thinking in a foreign language; I'm really confused about the switch part (for some reason, I "get" pull down resistor easier than pull up).
Anyway, just looking for comments, criticisms and thoughts.
