Newbie - Incremental Increase in RPM on DC motor?

Hi everyone,
I was wondering how I could incrementally increase the voltage going to a DC motor without an arduino. The motor is 6 volts. Is this possible? And what exactly is a soft start motor?

Thanks,
lprevs
 
Usually variable motor control is done now by way of a PWM control.
Soft start usually refers to power being applied with gradual increase from zero, rather than full voltage.
Max.
 
Well if the battery is 6V you can only ever run it slower than that. You could do it with a 555 timer wired to PWM driving a power MOSFET transistor which drives the motor in turn. Is there a reason you won't accept an arduino?

A 555 and a 4017 might do the trick, look up 4000 logic ic's.
