And the other way would be:


                3.3v
                  |
               o-----o
               |     |
              .-.   .-.
          10K | |   | | 10K
              | |   | |
              '-'   '-'
               |     |
               |     |
               |    ---
             o-+----/ v-------o 0/5v in

      0/3.3v out
