Flashing/Blinking LEDs

[kapnkrunch5]

I am a newbie at doing this but I was wondering if instead of just allowing the controllor to control the light pattern what if you connected flashing/blinking LEDs in series. Would that give you a more random flash pattern instead of a chaser pattern?

A flashing LED conducts only when it flashes. If it is in series with another flashing LED then they both might have no power and will not flash.
Maybe if they have a capacitor that slowly charges then causes them to flash, they both might flash at the same time.

Okay, That's what I was thinking. How about running them in parallel with a resistor it restrict the voltage? I have made a blinking led but only as a single flasher. I want to make a long line of random flashing. Maybe I should used different caps to vary the flash? Any ideas? Thanks for your time.

A parallel resistor does not restrict the voltage, it simply wastes battery power.
LEDs need their current limited, not their voltage. Leds set their own voltage because they are a forward-biased diode.

If you have a simple flasher circuit then make one for each LED. Electrolytic capacitors have a fairly wide tolerance range so the value of each one will be different and the flashing will have different speeds. Maybe you want a random noise generator to trigger flashing at random.
