Feather Huzzah Analog Problem

Post by bridge2nowhere »

I have a 10k pot attached to the ADC, Gnd and 3v3 pins of a Feather Huzzah. When I analogRead(A0), it reads 1023 when it gets to the middle of the pot.

When I use it with a UNO, it reads 0 to 1023 as normal.

Are you using the ESP8266 Huzzah? If so, its ADC has a max ~1V input:
