    Sure, Paul. See below. This is the project I built with it, though I have stepped away from it for a bit. There's also a 4th control (pot) not shown here.

    After learning more about the line-out possibilities, in the end I stayed with the headphone output. For my application this was better, with more granular control. I'm using an Adafruit TS2012 amp,...

    Looping back to this... the power supply was providing enough current, but there were some other factors. In the end, only a non-switching power supply with a transformer worked for this project.

    After a weekend away from things, came back with a few ideas. Still not getting anywhere.

    The power supply that always works is a PowerXcel USB Wall Charger like this one:

    OK, I figured it was just another way to declare a float, which I am doing as follows:

    float gestureVol = x (or whatever calculation I need)

    I can dig into this some more.
  6. Question about variable

    Maybe a newbie question... What does the "f" represent here?

    // Set initial volume
    // mixer1.gain(0, 0.5f);

    OK, thanks for the suggestion. I looked and I see there are a variety of choices. 30A seems like overkill for my project, but the 3A or 5A might be just fine.

    So do you think I should power this project with +12V, regulated differently to make sure I get a solid +5V?

    Just to offer moral support... I recently burned out a Teensy 3.2 in a very similar configuration!

    I had a similar issue, however when I measured resistance between GND and 3.3, I got something much less. 5V measurement was OK. The blink sketch trick above didn't work for me, but I am thinking my...

  18. Powering Teensy and other stuff together

    Looking for some help with solving a rather odd power issue I'm having with a somewhat multi-layered project.

    The main components are:

    1. Teensy 3.2
    2. Teensy Audio Board
    3. Adafruit TS2012...

    May have answered my own question...

    // SparkFun_APDS9960
    #define INT 0
    #define APDS9960_INT 0

    Using this, it appears to work. So I'm going with it!
