Hello! really new to all of this by the way.
I'm having trouble with one of the load cells showing up as well as uploading the code to the Arduino though it may be due to the first problem I'm not sure.
so I am trying to connect two load cells with 2 load cell amplifiers (one each) then to the Arduino Uno I have been following this video HX711 with a Four Wire Load Cell and Arduino | Step by Step Guide. but the video is only for one load cell and one load cell amplifier, so to be honest I just tried connecting it the way I thought it would work with my VERY limited knowledge
I have Attached a photo of what I have done and I will describe the photo now.
So the two load cells are connected to each Amplifier and then to the Arduino the first load cell set up is connected to digital pin 4 and 5 and seems to be working correctly, the second is connected to digital pins 6 and 7 but this one is not showing up on the Arduino IED. I have also connected both power wires together from the load cell amplifiers and connected into the Arduino and have done the same with both grounds (not sure if that is okay or wrong as well) the code I have been using is linked in the video but I will link it here too HX711_ADC library
not sure if I have given you enough information again I'm very new.
Any advice would be very much appreciated!
Thank you
All bets are off if you don't power the HX711 properly.
VDD of a Sparkfun HX711 board must also be connected to 5volt (or to 3.3volt for 3.3volt logic boards).
Try the "HX-711-Multi" library if you use more than one HX711 board.

P.S. both weblinks need fixing.
