I'm really new at this, but how can I know how much resistance as each resistor?

One way is by reading the color bands on the resistors. Check out the wiki, I believe there's some helpful things on resistors there. Another way is by using a multimeter that measures ohms. I'd go with reading the bands though.

Thank you so much.
Really helped me out. :]

Okay now wiring. I was wondering, did you guys send me two extra pieces or did I not do this right?

Which two extra? What kind of components?

47uif
and a 47k resistor?
I really don't know anything about this stuff.

Never mind the 47uif. Its used on the back of the pot.

so you should have the 47k resistor going to ground as well yes!.there is only one.....look at the schematic again....

the one that goes with the led?
I guess I'm good then. :]
is this a special wire or I can take any? I need a bit more and I have a bit laying around in my tool box.
can I use it if its similar size?

no the 47k that goes with your circuit...look along the bottom line of the schematic...

p.s ...an led resistor will probably be a 4.7k...not 47k....


edit:..sorry have you got a kit or something?,...

Yeah I have it.

The LED resistor is usually with the LED and the bezel.

The 47K resistor is the bottom of the schematic - look to the left of the word boost:

thats the 5k pot?

To the left of the word boost. 47K.

Yeah I know where it is on the drawing. But physically, what is that piece next to the resistor?
I'm really sorry about this guys, I'm really trying to understand.

What do you mean by this?
Title: Re: beginner project help needed
Post by: Martz on June 08, 2010, 08:42:00 PM
Okay that one I have in place. I have one left. Its a blue resistor.
With yellow purple black red and gold. Can't find that value. :/

That sounds like the LED resistor. Was it tucked in with the LED inside the bezel?

It might have fell, Its not here now.

Hmmmm now that sounds like a 47K resistor. Is it possible that you put the LED resistor on the board instead of the 47K? What's the color of the resistor in the 47K location?

lol.....sorry , but that WAS funny...!! :icon_lol:

Martz, did you get it to work?
