i am trying to get my fixed bowl that will be sitting on top of my load cell to be my zero points. can you tell me how to do this?my bowl weighs 0.147 kg and the analog reading i got is 96. i created a variable and set it to 96 and then subtracted analogValueAverage = analogvalA - variable. I do get the analog value to read zero, but when something is added to the bowl the analog value will not change why?i am getting:analogValue: 0.00 load: -6.40610
how can i get the results to be read in grams or ounces?
I am trying to calibrate my tal220 10 kg load cell by following your instructions, but I am confused in the code. For the first part where you said to enter two known weights I entered 0.018 kg for A and 0.308 kg for B. Am I suppose to put anything or comment anything out so I can obtain the analogvalA and analogvalB or do I put a 0 in where you have 200 and 600? The amplifier I am using is a ina122 with a 200 ohm resistor to get a gain of 1000. I am in the process of making an automatic dog feeder where the bowl will sit on top of the load cell to determine if the dog has food or not in its bowl. if you could give me any tips on how i can have the bowl as my zero I would appreciate it. Any help with how to get this load cell working would be appreciated!
Here is a schematic of how I have my circuit configured
