Good. So are you sure whatever sketch you are using during these 'tests' is writing a steady HIGH output and not switching between high and low at some rate, as your meter will give a lower voltage reading in reponse to a changing digital output?
it only puts out 1.5 volts and sometimes it will vary on its own up to the 5 volts.
pins 9 and 10 but depending on the sketch sometimes all of my designated output pins
