Hello everbody! new to the community, look forward to learning lots! i would like to crossfade 1w rgb leds with pwm, but i cant directly do it off arduino. so i was thinking of using a transistor, but need help calculating values of base, and collector resistors.. Id like the leds to run around 30…

please help configuring simple circuit

I wouldn't be too quick on thinking you have an answer. Plug it in, take some measurements.
