Has anyone made a voltmeter in MaxMSP?

    Using an arduino analog input, has anyone made a decent voltmeter that will display a range of voltages that you may expect to get?
    There are lots of ways to measure/display signal strength, but what about a simple linear voltage display?

      It's trivial though, isn't it? I mean, if the arduino takes 0-5v, and outputs 0-1023 - each unit is 4.9mV, as per the docs - then it's a simple scaling operation to get the value back again.
      [scale 0 1023 0. 5.] and you're set, as far as I see it.

      doh!
      glaringly simple. lol
