40ma limit ?

  1. I couldn't understand the diagram with them, so I winged it.... these are wired in parallel?
  2. The Specs days that require 20ma per unit?,
  3. is that 20ma in total when all 3 "Diodes" in side one RGB LED is Lit?
  4. is "3" is correct wouldn't the total current of all 3 lit LED's draw 60ma?
  5. if "5" is correct why do they still all light, when the max output of the Arduino pins(in this case the the Regulated 5v pin) is only 40ma?
  1. Yes. Parrallel.
  2. Yes, 20ma per diode (ie 20ma for red, 20ma for green, 20ma for blue)
  3. See #2.
  4. If you are running all colors simultaneously at max continous current, then yes, 60ma total is flowing through the LED.
  5. The 40ma limit is for each pin controlled by the Arduino. In this case each pin is only controlling 11ma or 7ma (based on 270 ohm resistors), depending on which color your are using.

The 5V pin is not controlled by the Arduino. It is limited by the Voltage regulator or your USB port.
