Sure. Mount them on a small PCB, with a header connector at one end, and connect to the uC board with ribbon cable, probably with IDC connectors.
Or you could achieve the same thing by just taking 11 conductors of ribbon cable - you can get this from any ol' scrounged ribbon cable, and split it up and form it like this:
bent ribbon wires bussed v v ,----------------------[LED]---+ | ,--------------------[LED]---+ | | ,------------------[LED]---+ | | | ,----------------[LED]---+ | | | | ,--------------[LED]---+ | | | | | ,------------[LED]---+ | | | | | | ,----------[LED]---+ | | | | | | | ,--------[LED]---+ | | | | | | | | ,------[LED]---+ | | | | | | | | | ,----[LED]---+ | | | | | | | | | | | | | | | | | | | | | | 10 9 8 7 6 5 4 3 2 1 VCC active low
You can just tin the stripped ends and wrap them 3/4 turn around the LED leads, like winding them around a post.
Have Fun! Rich
