Hi,
We cannot get the drum glove to work. We followed the instructions for the build and finally got the Adafruit boards installed with a link someone posted on the forum to add board URL in preferences. Now the program won't work with the Flora. Please help. We installed NanoStudio, but do not know how to make it connect so the glove fingers can operate as the keyboard presses.

Re: Midi Drum Glove Project
Back up a little and go through the basic FLORA intro guide:
https://learn.adafruit.com/getting-star ... a/overview
Make sure you can get the blink example to load and run first. If you still have trouble with that, report back.

Re: Midi Drum Glove Project
What errors do you get and what does not work?Now the program won't work with the Flora.

Re: Midi Drum Glove Project
We've already gotten the blink to work. We also made a lie detector last year and a GPS jacket (it was much easier on a Mac, but now we are using these at school with Windows!!).
The problem we currently have with the midi drum glove program is that the word 'keyboard' in the program errors out and is not recognized. How can we connect to the music program? Any help greatly appreciated.

Re: Midi Drum Glove Project
Try putting this line at the top of your sketch:
Code: Select all
#include <Keyboard.h>

Post the code you are trying to compile and we will take a look.

I tried the include keyboard line, but that is errors out too.

Re: Midi Drum Glove Project
What version of the Arduino IDE are you using? Check and make sure the Keyboard library is installed:
Sketch -> Include Library -> Manage Libraries...
type "keyboard" in the "Filter your search..." window and make sure the library shows up in the list.

Re: Midi Drum Glove Project
Thank you, I installed these libraries and now the program says it uploaded, but it's still not making any sound. I have NanoStudio open - how do I make it communicate with Flora?

Re: Midi Drum Glove Project
I also put these includes at the top of the program:
#include <HID.h>
#include <Keyboard.h>
#include <HID.h>

Re: Midi Drum Glove Project
If you open the serial monitor in the Arduino IDE, do you see anything being printed there when you try to use the glove?

Re: Midi Drum Glove Project
No, nothing is printing in the serial monitor, but I do see on COM13 (Adafruit Flora)

Re: Midi Drum Glove Project
Hmm. If you're running the first demo code from here (with the needed #includes added):
https://learn.adafruit.com/midi-drum-glove/code
you should see some output printed to the serial console when you try to use the glove. Something like:
Try lowering the value for threshold on this line:
and see if you can get the glove to respond.

Re: Midi Drum Glove Project
I went down to 10, still no response. I could not get the Flora board choice from Teensyduino to show up. Could this have something to do with it? I only see Teensy 3.6, 3.5, 3.2/3.1/ 3.0 LC, 2.0 and ++2.0 We chose just the regular Flora.
