is there a way to increase the light of an LED with a dial?

[Smitty Two]

I would like to think that he understands at least a bit about it now

Well, Victory, would you like to substantiate this by answering a couple
of questions about what's going on with your new circuit?

1> What does the pot do? In other words, how does it change the
brightness of the LED?

2> What purpose do the two most widely spaced terminals on the pot serve?

 

[Victory]

Sure, I will bite, if only for Arfa sake because he doesn't seem
grumpy.

1) The pot varies the resistance of current going to the LED. So, as
you turn it, the current gets stronger or weaker (brighter or dimmer),
until it is turned off.
2) The widely spaced terminals are for the OFF/ON switch of the pot.
I tested those separate and they turned the LED off and on as far as I
could see. When the current is interrupted by the switch being in the
OFF position (ie; the circuit not completed), the LED receives no
power from the battery. When the switch is turned on, the circuit is
complete and therefore the LED receives power from the battery.

How does that sound?

Surprisingly credible. You've gained more than I suspected.

Arfa and others are good teachers.

 

[William Sommerwerck]

Arfa and others are good teachers.

And Victory ought to be immensely grateful that so many busy people spent so
much time helping him with Electricity 101.

If he's genuinely grateful, he'll pick up a few books and teach himself some
more.

Well done !

See Smitty, I knew it was worthwhile giving it a go ... ! You could say, a
'bit of a Victory' Ha! Victory ! Geddit ?

Thanks Arfa,
Just trying to find a really small Button battery (cr2032) holder. It
is all going really smoothly thanks to the helpful members of the
group.

Just as a matter of interest, what is this project for ? Don't have to say
if you don't want to. Just nice to know where some of these left-field balls
come from ...
