Is there a programmable 9V motor?

Question

I was just wondering if ther eis such a thing as a programmable 9v motor, or even better a way to do the whole thing, im really into this subject right now, and i was wodnering where i can also refer to?

well, i want to program, tempo, speeds, and times. thats all

and i also need to know how i can program it, preffereably by connecting it to the computer

Answer 1

What do you want it to do under program control? Should it run at some chosen speeds? Should it stop at specific points in a revolution? Should it change direction?

You might be best off getting a stepper motor and making a pulsing control that can be programmed to achieve your goals. The combo of motor plus controller chip should be able to do anything.

Answer 2

A motor, and just a motor that is programmable, no. Can speed control of such a motor be accomplished, yes. A PIC controller would do the job quite nicely.

Answer 3

A 9 volt motor can be controlled by a computer through the use of an electronic speed control. You can think of the speed control as an amplifier.

Brushed DC motors are the easiest to understand and control:
