hi again.
I am using this schematic:
http://www.dprg.org/tutorials/2005-11a/index.html
I have replaced Q1 with a tip122
and both diodes have been replaced with 1n4001.
i can hear a slight slow down of my motor, but it's not nearly what I want. Is this because of the pot value, R1? Will lowering the duty cycle help? I'm guessing a much larger pot will help me out?
ps, don't you hate when you have piles of potentiometers and can't make out the values on any of them? arg.
ok, and sorry one more edit...this is gonna sound REALLY dumb, but does a higher or lower frequency make a slower motor?
