Hey everyone! New user here, and not that experienced with electronics (as far as putting them together).
I'm trying to setup the lighting for a prop I built (a replica of the gun from Portal). I will have a sequence of 11 orange LEDs and 11 blue LEDs with a switch to go from one to another. What I am wondering is if I need to have resistors with that many LEDs. I saw this project where the guy had a similar number of LEDs in sequence, but he didn't use a resistor. Welcome to Slothfurnace.com... Tasty!
Here are the LEDs I will be using.
**broken link removed**
Forward Voltage: 3.0-3.6v
Current: 20-30mA
**broken link removed**
Forward Voltage: 1.8-2.4v
Current: 20-30mA
Here is how I would have to seperate them. I will be lighting up different sequences of the gun.

I assume I will have to set them up somewhat like this.

I don't know what voltage I need, or what kind of resistor I should use.
