I’m trying to read the output envelope from a Sparkfun Sound Detector with an ESP32. It outputs an analogue value. However I do not want to read it as a voltage, I need to see it as Arduino would - i.e. 0-1023 so I can do the conversion to decibels.
Am I missing something - can I not read the numbers going to the pin directly or must I use the ADC route which seems a bit bizarre as the voltages are not so easy to convert!
Thanks in advance.
