| Oct 28, 2017 at 17:31 | comment | added | Trevor_G | @eidylon please note I changed the second schematic. Having the R below the emitter in this version may put the emitter voltage too high for the micro to turn it on. I'd also try it without the extra transistor first. I think it will likely work fine without it wired this way, but put a base R bin. | |
| Oct 28, 2017 at 17:28 | comment | added | Trevor_G | @eidylon No. LEDs are current driven animals. Having them in series, they all have the same current so they should all be about the same brightness. Putting them in parallel they are never the same. | |
