I am using a Arduino MKR Connector Carrier in my project and i am noticing that when 5v is applied to an analog input via the Connector Carrier it translates to 3.22v in the Arduino with a ADC value of 1009
This is messing up my reading in the MKR1010 that i am using. I am using a 5v sensor so i need to get accurate readings.
I know the carrier has built in voltage dividers into when i tried to measure them R1 was at 472 Ohms and R2 was at 911 Ohms.
Can some one help me figure out the best way to calculate the voltage accurately.
