I've been relying on the online calculator to do the math but when I did it manually this is what I found  for 9v...

White LED = 3.3)  9 â€" 3.3 = 5.7 / 0.02 = 285 ohm

Blue LED = 3.3)   9 â€" 3.3 = 5.7 / 0.02 = 285 ohm

Green LED = 3.3)   9 â€" 3.3 = 5.7 / 0.02 = 285 ohm

Red LED = 2.0)   9 â€" 2.0 = 7 / 0.02 = 350 ohm

Orange LED = 2.0)   9 â€" 2.0 = 7 / 0.02 = 350 ohm

Yellow LED = 2.1)   9 â€" 2.1 = 6.9 / 0.02 = 345 ohm

They came with 300 ohm resistors for white, blue & green; also 360 ohm resistors for red, orange & yellow.

By my manual calculations I should be fine to use the resitors they supplied.

Thanks for helping clear that up!
