Step 5: Assembly

Once I had the standoffs mounted on the Arduino board, I moved the parts around to see where they should be mounted. The Velleman breadboards have little dovetailed brackets that hold them together. I left the bus boards in between the breadboards, but if I were doing this again I would have moved them to the outside. I think its more useful to have shorter gaps between the vertical traces than to have the extra bus lines in the middle of the board.
