Thanks for the reply, I'm sorry but my explanations are terrible (I'm working on it
). I was trying to say that, as a completely standalone device (no USB power) could my external supply power both pins, ie give me a 5v pin to use and a 7.2volt pin concurrently?
And I'll repeat:
Yes you can use both the Vin voltage and the +5vdc voltage to power external devices from the Arduino board. However keep in mind that both those voltage sources have current limits that you can't exceed.
When using the external power connector, the voltage it provides is also avalible at the Vin pin (which will be the same voltage as the external applied voltage) for use to power external devices. The +5vdc pin is also avalible to power external devices. Again both voltage sources do have maximum current capacity that you can't exceed.
