It seems to me that 30 LED's would be drawing way to much current to sink or source from the 555. I could be wrong(probably am). Could you explain how the 555 which can only handle 200ma can supply 30 LED's?
I don't mean to doubt you or anything, but I am fairly new to electronics, and rather than just have someone tell me to do it a certain way, I would like to know how that way works before I do it.
Also, are there any sites for setting up circuits to make pin 3 low or high at a certain frequency? Thanks again guys. You guys are great. It is all starting to make a lot more sense to me now.
Like sinking and sourcing. If I sink the current, the LED's would turn on when pin 3 of the 555 is low. If I source it, they will turn on when pin 3 is high. One other question, pin3 will supply the same voltage that my supply is, correct?
