If you are on a windows OS and can only see COM 1 then the first place to start is with drivers as you would expect an Arduino to show COM 3 or above as 1 & 2 are reserved for internal windows usage.
A picture of you board (in focus) might also help here or a direct link to where you got it.
It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google (who would have thunk it ! ) or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.
