Much sooner meaning straight away IME ;) Also, since the blue and green appear brighter then the red, calculate the resistor for the red and use that on the other 2, he blue and green will be a bit dimmer but nothing major. |

Sorry for replying so late. Here is a pic of the LED (sorry for the low quality). Would I need a resistor for every LED or just for each string? If i do get a resistor how do I wire it to my pc's power supply? |
| ivwshane:
Can anyone answer the above question (how many resisters do I need)? What type of resister do I need (yes I'm a noob when it comes to this stuff). |

Back when I used to work with LED's I believe I used to put 1k Ohm resistors for each LED. |

You need to know a few details before you can figure out what resistors to use and how to wire them. * Source voltage you are using (either 5v or 12v from your PSU) * LED forward voltage (should be somewhere around 3v) * LED forward current (should be somewhere around 30mA) * The amount of LEDs you wish to light When you know all of them put them into [this] calculator and it will tell you which resistors you will need and how to wire them (series/parallel/combination). |
