    Thank you for your valuable advices,
    For the advice to to measure the Vref with a good digital voltmeter, this is a good advice. However, in practical, I think if we have a good digital voltmeter, we don't need to make a DIY voltmeter any more. When I made this project, I just think to the case that someone does not have any voltmeter in hand.
    Thank you again for your advice

    Hello Don Breedlove,
    I did not know your comment soon because I do not receive any notification.
    Did you use PHPoC Shield, or any other shield?
