Hello all,
I am an absolute beginner at electronics. I need a DC motor (probably a 1.5 to 9V hobby DC motor from radio shack).
I need to be able to vary its rotational speed.
By chance, I happen to have a 555 IC. I don't know how to read a schematic, is there some way I can use it to build a pulse width control circuit ?
Any other suggestions ?
Please help !
Thanks a bunch, Jj
By Googling the phrase
"555 +PWM" (no quotes), the first link that comes up is:
This'll do the job.
Good luck Chris

By the way, JJ, this page seems to be oriented toward newbies, but it still requires a little background. Take a look at the page, and post back if there's something you don't understand.
Good luck Chris
