I am wanting to use a Audrino Nano to weigh an item on a set of 4, 50kg bathroom scale loadcells. I am wanting to do this without using a HX711 amplifier board. The scales do not have to be extremely accurate, just a accurate as I can get using this method.
Can someone please explain to me (in truck driver English) how I would be able to get this done.
I believe the HX711 signal is too small to get a reading. ?20mv max? Find a datasheet.

The output of load cells is waaay to small for the Nano.
You need a HX711 to process that to a level an Arduino can work with.
If that Nano is not a classic 5volt Nano, then you need a special version of the HX711.
