Play A Diminished Arpeggio on the low D string at frets 1, 7, and 10, saying each note name and degree aloud.
Build a phrase that lets A on open string 5 ring, then connect it to the nearest A root and two other arpeggio tones.
Connect the A root positions on strings 6 through 1 at frets 7, 0, 7, 3, 0, and 7, adding the nearest arpeggio tone between each pair of roots.
