Newbie for lightsaber

[joqueen]

I am from Taiwan. I learn to build my lightsaber with the RGB LightSaberOS-master. I want to build a colorful one. There are some problems need your help. Thank you.

1.  If I build with the RGB LED like the figure what type do I choose ? (＋、R、G、B) or (－、R、G、B)  
2. And which blade type I need to choice in the confing.h?
3. Which Arduion nano pin wiring to led(R、G、B)? I found config.h A2->R, A3->G, A7->B. Is it right? 4. Or you can recommend what led type more suitable for set up the saber. And please give me the led spec. and led photos.

5. Are the S1~S6 5V voltage regulations?
   

6. Can I use the model:7805 voltage regulation? OR what model do I need?    
   7. The blue led on electric circuit is just for one color saber. I can ignore it?

Thank you
