Hey all...I need to wire 10 red led's (1.9V@20ma) from a 9 v battery. I was going to make them sequentially flash, but the flahsing circuit wouldn't cooperate no matter how many times I re-wired it.....I just want them to go on, and am struggling as to how to calculate the resistance needed, and the best way to do it.....2 parallel sets of 5 led's wired in series? If that is the best way to wire it, am I correct in figuring I need 52 ohm resistors on each led? (I realize I will have to get 56 ohm). Thanks for any info. on this one....
