• Aaah, ya. Last I checked, analogRead read from the adc pin ( the only one it can read analog voltages on) regardless of what pin you told it to read. The adc is 0~1 volt only.

  • Now I understand - I used to send it this way and it complained:

    >analogRead(A0)
    Uncaught ReferenceError: "A0" is not defined
     at line 1 col 12
    analogRead(A0)
               ^
    

    .... All I had to do was send it like this analogRead(); to get it work!

    NOTE: On the WeMos website they mention that max on the analog read is 3.2v... we sill see.

    Thank you all!
