ESP8266 Community Forum

Hi, can anybody help me how to use gpio2 in esp8266-1 as an analog input pin? or is it possible?
I have been trying to program my esp-1 board with analog read command and it only reads 0 or 1023.

no, the analog input is a special pin not available on the pinheader of the esp-01.
If you are very good at soldering and have a steady hand you might be able to solder a wire at ADC/TOUT (pin 6 of chip).
