I'm a newbie. I see DC motors, stepper motors, servo motors being used in projects. I'd like to know the advantages and disadvantages (circuit complexity, cost, programming) of each.
My son is interested in using 2313's along with K'nex & Legos to build some creative robotic ideas. I have some old CDRom drives and 5.25 floppy drives that have motors and steppers but have no clue where to go from here.
Any input or referrals to info would be greatly appreciated.
