Hello I an new to this forum. I want to use my Nano R3 to read and convert a 0-1 volt dc oxygen sensor output. A mV output signal converted to display Lean-Stoic-Rich. A conversion based on voltage will be needed for a display. I know narrowband sensors are just a rich/lean indicator. Just looking for another way to use my Nano. It will be in a vehicle with a slightly variable voltage supply. I assume a voltage converter will be needed to provide a stable input voltage to the Nano. Aftermarket gauges are available with led sweeping indicators that would be nice to add too. Rich would be the upper range, stoichiometric middle, and lean at the bottom of the voltage signal.
Thanks!
