ESP8266 Community Forum

I can't find any detailed information about the analog input of the AdaFruit Huzzah ESP8266 board. The only thing the specs say is that the input voltage is limited to 1.0V max.

How does software access the A/D? Is port setup required? What's the resolution? Any special considerations? What's the effect of the analog source impedance?

Check https://arduino-esp8266.readthedocs.io/ ... alog-input.

TL;DR: same as arduino: analogRead(A0);
