I am trying to send a pulse of 5V, 5 millisecond from PIN 7 (or any output pin, for that matter) to NI 9411 6-Channel Differential Digital Input Module. As you guys can see page on page 16/17 of this manual http://www.ni.com/pdf/manuals/373506e.pdf , the input current rating of this input module is mere 1-2 mA. I am thinking Arduino Uno can provide this much of current. Things have not worked till now.
My first question is, can I programmatically access the current through PIN 7 as the current through the PIN is so low (is that true?), my current probe w/ Tektronics oscilloscope is not able to pick up? I am not sure if any current actually flowing through it not. PS: I can see the voltage pulse of 5V off the PIN7 on the oscilloscope.
Has anyone ever tried to work with NI controllers/DAQs with Arduino? Any help is much appreciated.
