How is speed controlled with this DC motor board?
Manual is attached.

Should have looked first.Anyhow here's some info.

Take a look at Activity #2 of Chapter 5 in Process Control on page 141 (151 in the PDF).

Just figured out the IC on DC motor board is same one we got from Parallax.
I don't remember getting a DC motor from Parallax.
Can't think of what it is used for in Parallax lessons right at the moment.

That IC is commonly used to drive bipolar stepper motors.

That's it! Thank you.
Thought of why PWM sounds familiar.
Is hardware PWM in a CCP more serious than software PWM?
Guess the thing to get is standalone CCP module.Maybe.

Got to the bottom of CCP modules.
That is a whole subfield of using micro's.
Off the table for now.
Software PWM is just fine.

Got 77 cents?
"When you make a thing, a thing that is new, it is so complicated making it that it is bound to be ugly. But those that make it after you, they don’t have to worry about making it. And they can make it pretty, and so everybody can like it when others make it after you."

The DC Motor mini board does cost more than 77 cents but you just connect it and it's ready.
We have enough to do figuring out PWM.
H bridges are handy to have around.Thanks.
