Hi, i'm designing a bubble machine, and need to slow down a 3v motor, and not sure on what resistors to use. I need to slow it down enough so it rotates a wand and dips into a bubble machine and that bubble then gets blown out using a fan. The motor runs at 5,240rpms, i need to decrease that by alot! The motor will run from AA batteries.
Thanks to any one who can even give me the slightest help.
