In these three examples I've used some pedal point notes. (Here they are alternatively repeated with chords, although this technique is also very often used in flatpicking. )
I think this fingerpicking use of pedal point must have its origin in the piano style of playing. (The same as walking bass) The best thing is to play the examples slow enough at first so that you give a little time to your neurons to make new links. I've learned too that isolating difficulties helps a lot in making things finally work. Don't think this is too hard a job at all, even if you are just beginning. Learning to play things like these has been very rewarding to me and I hope you will enjoy the experience too.
Just in case you need it, this is a list of the chords that go along the pedal point notes with their names and composition.
