i have been trying for a few days and searching this forum but i cannot seam to solve what should be a simple setup
i have 2 half bridge loads cells (http://www.sparkfun.com/products/10245
and this op amp (http://www.national.com/ds/LM/LM741.pdf
i am trying to get this to register in arduino. from what i know so far is that since the load cell is a half bridge i can use two to make a full Wheatstone bridge. but i either got the wrong amp, i read a lot of talk about using an ina125p, is that better?
here is a diagram, can someone help me fill it in.
