P------|------------------P

i meant to do exactly like this:
but, whats the max that i can put ? what should be max current/voltage of the adapter?
and do i need to feed the arduino as well? or it "know" how to use the power from the "VIN" pin?
- about the Continuous Collector Current, is it 20mA after the resistor?
what resistor should i use? i think the blue and green should be 220ohm, and the red 300ohm. (but what do i know
)
thnx
