That sounds like it might really help us. I would appreciate it if you could post the modified circuit. To make sure I understand correctly, you use the pot to adjust the voltage coming from the voltage divider?
The problems with that are that the I am using the Arduino as my power supply and obviously my max output voltage is limited to the 5 volts of the Arduino. Also the A/D takes inputs from 0 to 5 volts. The full scale output is only 9mV (before amplification). So for my preload the sensor...
I am using an instrumental amplifier and the output is a voltage that I'm putting into the A/D input. The load cell has four wires. One is power, one is ground, and the other two are used to actually get the measurement (difference in voltage). So I am thinking that the only way to remove the...
I am trying to use a 0-5000 lb load cell with an Arduino. My issue is the 10 bit input on the Arduino. The load cell will actually be pre-loaded to about 3800 lbs. I just need to measure up to a couple hundred pounds difference. The load cell is a standard 4 wire and measures the difference...
