What is the Max Current to Draw from 5V Pin Safely? Is it 40-50mA like the digital i/o pins?javascript:void(0);
No it's limited by the power source the arduino board is using. USB can provide about 500ma limited by the on board thermofuse. If on external power maybe a little more depending on the exact voltage you run the external power (or Vin) at. The basic board consumes about 50ma or so, the rest is available at the 5V pin.
