Hello,The idea of this activity is to measure the Vo; for the Multisim simulation I used 3 7-pin 741 Op-amps (please see pictures below), and to assemble the actual circuit, I used 3 LM741CN Op-amps. I’m having a really hard time figuring out how to connect my Diff-amp to MyDaq, could you please explain me how to connect this on detailed? I’m attaching pics of what I have done so far. Thank you

I suggest you draw on paper the schematic of your breadboard as you have wired it, to see the errors in your breadboard wiring.

It looks like there were 4 pics and one did not come out, we got one of your MyDaq connections, one of your breadboard, and one of the info you have to find. As peter says, a schematic would be good. I have a MyDaq as well and may be able to help you further.
