The Arduino's ADC is proportional to the AREF it is using, and you need to make sure it's consistent. Also, I think the Arduino Mega needs more than +6V for the system to draw power through VIN. | |

I ended up having some success by increasing the impedance (mega ohm resistors) between my probes and the Inst. Amps. (similar to how a multimeter works I think) but it didn't provide the resolution that I needed for the project. I ended up just implementing a rotary switch method that allowed for the load cells to interact with one system at a time. Not the best solution, but a solution none the less. Thanks for the suggestions Andy! | |
