Need a LED circuit to simulate candle
Hey guys, I'm hoping somebody here can help me out. I'm a newbie when it comes to electronics and whatnot. I can read basic electronic schematics (I know symbols for resistors, LEDs, ground, etc). What I'm wanting to do is create some Halloween decorations for my niece and nephew and their friends, which is basically a hand held lantern that has flickering LED's behind frosted glass to give the appearance of a flickering candle. There are several nice instructables I've found here that cover LED flickering, but at most they're dealing with things I'm not really comfortable with (555 timers and other IC's, programmable chips that use hex coding, etc).
The effect I'm looking for is a red LED that doesn't flash along with a orange and yellow LED that do flash to give the appearance of a flickering candle flame. I've found a few places that sell these kinds of kits, but I'd only prefer to buy them as a last resort. Since I'm building several of these lanterns by hand, it would really be easier if I could buy several parts (LED's, resistors, caps, etc) and put them all together myself to save money.
As I understand it, you can vary the values of the caps and resistors to get not only varying times of flash, but also a fade in/out effect. I think using a 555 timer would probably be easiest to get random flash patterns for the yellow and orange LED's. I'm not opposed to using a 555 timer, it's just I've never used one before and it's been difficult looking at the instructables here that feature 2 LED's that flash or 40 LED's flashing and trying to figure out how I add a solid non-flashing LED into the mix.
Would it be simplest to simply buy a flashing orange and yellow LED and then use a cap and resister of varying amounts attached to a battery along with the non-flashing red LED to achieve this affect? Or would it just be simpler to use a 555 timer with two regular LED's to make them flash, and then wire the red LED I don't want flashing outside of the timer's circuit (I guess parallel to it so it still runs off the same battery?).
I had considered using 5mm LED, though I'm honestly not sure how bright these would be. I'm not wanting the room to light up like the ceiling light was turned on, but bright enough to definitely be noticeable. I'd also prefer to either run these off of a 9v battery for mobile use or wire up a 12v DC adapter to it for a more permanent solution.
I've seen a few sites that offer "single flasher led" schematics, but again, I just don't know how to add another LED to that circuit to have two that flash at different intervals as well as how to add a third LED to it that WON'T flash. I've also seen people use the modified LED tea candles, but again, that is a single LED and I just don't know how to combine that with another (or 2+) LED's in a circuit so they all operate safely off of the same power source.
If anybody could lay out the diagram for the three LED's (or if you think it would be brighter to use 2 of each of the 5mm LED's I want to flash for a total of 5 LED's) along with either the r/c circuit or the 555 timer circuit, I'd greatly appreciate it. Like I said before, I've scoured through all of the flashing LED tutorials here, and while they're all really great, there aren't really any that fit my needs and because I'm a novice with this, I don't know how to take the information that's given and apply it to my needs :(. Maybe I need layman's terms for the setup lol.
I'm sorry if this is all long winded and a long read, I just wanted to supply as much info as I could to make sure I was (hopefully) understood fully :)
