I'm shooting for only having 3 LEDs lite up, or when th switch is thrown it switches to a different three.
Cool. So bigger saves Power. And I am safe in using 1/4 or .25 watt resistors.
I see it does not matter where the resistors are placed, as long as they are in the circuit. So now I just need to do the math to figure out how much they need to resist. Since I mam going to want to have white/white/green up. Can I assume that I can use the full power of the two whites, and tie...
So, now that I can see the the images I see what you are getting at. However, I'm just making sure that the resistors are placed right. They are on the negative side of the LEDs. Or Common pole to negative terminal of the battery?
Yes. I could post links to everything if that would help?

Standard 23a 12volt Battery
Resistors, have not done the math for, but they will be bought at Radio...
Okay, well that takes out the momentary switch, and we will just make room to accept a double post double throw switch, and manually change it when ever events occur.

I am fairly new to building electronics, I...
Good afternoon,
I am attempting to build a LED Circuit that is more complex that I know how to do. It runs off of a 9 volt battery and 3 LED's.
First off the Math
Battery 9 volt
3mm Red/Green LED
Red: 1.9-2.5 Volts @ 20ma
Green: 2.9-3.5 Volts @ 20ma
5mm White/Green LED...
Maybe if I explain what its for that might help. And sorry for the poor art skills.
I play a game with models cast and built in the 28mm heroic scale. We have a tank, with a back hatch that drops open. I want to wire it up with LED's to make it stand out more. Two of the LED's will be for...
So I am working on designing a rather simple LED circuit. In theory at least. It looks something like this.
However, I am wondering if its possible for me to change one of the LED's to one that alternates between green and red on another switch. So that when say the switch is closed, its...
