Hi people! I have thsi basic chaser circuit: but the outputs are going to be switching alot of LEDs, about 20 of them and at 20ma each that is 400ma. the 2n3904's there are not powerful enough for this (max 200ma) so i was wondering what i could swap them with that would give more juice. The whole thing is going to work off 5v. cheers! on a similar note, if i wire 20 LEDs in parallel with one reistor (all same) then will the resistor be the same as if i wired 5 in parralel (same as above).. Also, my calculator says i need 1watt resistors for this... is this true? thanks alot!
