Analog pin

-

hi,

i wanted know how voltage safe provided analogue pins of arduino uno ?

i have interfaced arduino labview , want measure voltage of battery more 6v , reluctant since arduino can not take voltage more 5v, guess!
so can please confirm me ?

thanks :)

the maximum voltage can apply supply voltage pluse 0.5v.

the simplest solution use potential divider.
