A few questions for a remote sensor project using an LC. I have an LC waking from deep sleep reading a Bme280 sensor, every 2 minutes, sending the data and going back to sleep. I would like to read the battery voltage powering the LC (3 x 1.5v AA batteries) by the LC ADC and include this data to send. Looking at the ADC example and reading the ADC lib does the LC having no ref voltage out create a problem? And can the 4.5v battery voltage be fed to a potential divider and then read by the LC ADC to give full scale reading? Sorry if these are basic questions but I have not used an ADC before.
