Shouldnt be too hard, only problem is that the loadcells can out out up to 8.8v... too high for the Analog pins i think. How can I turn the 8.8v into 5v? Resistor? I would prefer not to have to completely redesign the load cell setup to run on 5vRyan
Can you provide a link to your load cell device? Most we see are very low voltage output devices, millivolt outputs usually requiring a op-amp to interface usefully to an arduino. So any advice we could give should be in context with a datasheet based on your specific load cell.
If indeed your device outputs a 0 to +8.8vdc measurement signal, a simple two resistor voltage divider using a divide by 2 ratio (two 5k ohm resistors in series should work fine) would work easily for an arduino analog input pin.
