I have 100 blue diffused LEDs that I want to use (not necessarily all of them) to make some kind of circuit that would likely just crawl over my wall like some vine growth coming down from the ceiling and twisting downwards to the floor, held in lots of places by pieces of tape or other adhesive. When I bought these they also came with a pack of 100 resistors that read 0.455 when I measure them on 2k scale of my multimeter (so ~500 Ω?).

I am not sure how to check the voltage for the LEDs, they do glow blue when I check them with the multimeter at 2kΩ but I assume since they are blue that they are probably meant for around 3.5 V and draw standard 20 mA. I also have a 9V battery at hand but I suppose I could get a bigger one if needed.

My question is: How should I connect these LEDs (let's assume I am using all 100)? I know the difference between serial and parallel and having them all in serial would probably take alota lot of voltage right? So should I make X parallel branches with Y LEDs in each? What kind of wire should I use? Can someone help me create this circuit and also point out anything I should know by the way?

Thank you :)
