LED wiring question with diagrams

(1/6) > >>

Timoe:
I would like to wire a simple set of (4) leds to one 5v source.  I have attached a blank diagram for your use and a sample diagram of what I think will work.

1. Will my idea work?  If not, what corrections are needed?

2. Will only one resistor be needed?

Kaytrim:
Sorry Timone, you may blow your LEDs in that config.  The resister is divided amongst all the LEDs in the chain.  You are better off adding a separate resister to each LED.  This is the reason that I purchase all my LEDs from GGG.  Randy supplies the proper resister for the LEDs he sells.

Timoe:
So then this should work?

Kaytrim:
According to Wikipedia you have the resister on the wrong side.  Look at the section titled "Considerations in use" in this first link to the main LED page.  This second link is to a sample circuit.  Below is what I understand as being the proper layout.  I also included a pic of my LED boards that I put in buttons.

TTFN :cheers:

Timoe:
Perfect, Thank you.
