    Sorry for the late answer I had some stuff to do.
    Okay so, the circuit is connected like this:

    Voltage: V+ which is the 5V DC connected to SW5
    Ground: Ground to Ground
    Analog = PO or PH analog output is connected to the Analog pin A0
    I used three resistors to test which one will be close to the voltage required, I will post a picture of the three of them.
    The voltage output I get from your code displays more than 5V, I can’t calibrate it to 2.5V that way.
    The circuit is guarantee is properly connected.

    Also you have been helping me out a lot, I appreciate it.
