Hi everyone,
    I'm still new this field and i'm learning as I go with this microcontroller. My question is, Is there a limit on how much voltage that the analog input pins can take? I've read that by default the voltage reference high is 3.3V. However, I did read that you can change this voltage reference. I'm kind of hesitant to change the voltage reference due to the fact that i might "fry" the board. Any info that you can provide will be much apprieciated, thanks.
