hey, the standart measurement of Voltage on arduino are at max 5V measurement range, between 0 - 1024. That's like the Values u can see, but only higher.. i dont know the max Value of measurement from unipi, but if you put 10V at input u can see (maybe anywhere over 408421.875 i think, i name 5000000 as max at 10V here). Set this in relation 0v-10V to Value 0 - 5000000 so you can count your Voltage.
