That is actually how I had it set up initially for testing when I was using a less sensitive force sensor. I am now using the 100 pound sensor I plan to use with my project. This one is just so insensitive though, I figured I would set it up the way the schematic told me to. I am using a 10k trimpot shown below for my project. Maybe I need a larger trimpot (100k) to get the results I need? I could probably whack it with a hammer and have it barely light up the reference LED. I need it more sensitive than that lol.
