Good day forum peeps! I currently have an Arduino due and a sensor that outputs analog voltage from 0-5 volts. Any recommended hardware or circuit that can do that so the Arduino Due won't be damaged?
I'm kinda new here so sorry if I have wrong English XD
Just put a potential divider on the sensor e.g. with 10k and 20k resistors for 2/3.
Then read the resultant 0 to 3.3V from the pot.
Multiply the result by 3/2 to scale it back to 5V.
Your resistor values need to be a happy compromise. 10k is a reasonable source impedance.
What output impedance does your sensor have?
David.
Thank you sir for the reply...
well i actually have no idea about the impedance of the sensor and i also have no idea what impedance is 
is there a way to identify it?
