1 Connect ground to X11 block for LED you want to test.1 through 6 (L&R,1-3). More than one can be grounded and will become 'live'.
2 Connect jumper wire to 3.3v or 5v block.Briefly insert jumper into each X10 connector socket of LED segment and it will light up.
Here are helpful links for PPDB schematic and Parallax Object Exchange lookup table of pre coded letters and numbers.
