i'm very new to this and have been playing around with the sample sketches
i've been trying out ReadAnalogVoltage and doing ok, however, my project requires that i monitor the status of my 12 Battery between 10 and 15v(to also allow for the charging voltage).
a bit rough and ready but i'm using a 19v psu with a pot to work out min/max voltages i am sending to my voltage divider.
from what i've seen, the UNO can only accept 0-5v on the inputs, so with my 3:1 divider i should be able to work out what the readings correspond to.
however... stupid me didnt connect the variable voltage to the top of the divider, i stuck it straight into A0.
there was a slight burning smell and now my processor runs quite hot and none of the ADCs are working.
i'm assuming i've fried the chip ??
if that is the case, what are my options? can i just order another ATMEGA328P-PU chip or does it need some form of programming first before swapping it out?
