There are no particular behavior for the lights. But it's better if we can control how fast it flickers. The light that we will be using are LED. The minimum requirement is 8 LED lights.You need to define and describe what you mean by "christmas lights".
What are you using for lights?
How many lights?
How should the lights behave?
It's better if I can do all of that in a circuit, maybe with the help of switch? I can make them flicker at the same time and randomly.Still not clear what you want to do.
Are the LED or LEDs flickering at random or oscillating at a constant frequency?
Will all LEDs flicker at the same time in unison (i.e. they all flicker in exactly the same way)?
Or will each LED flicker at random rates independent of all others?
