The Adafruit Huzzah is also fine, it can send OSC over the Network to your Show PC. Much easier to setup then Serial communication. Please be aware that you should have a solid isolated network for this types of things. (That can do both 2.4 Ghz as 5Ghz, since micro controllers most speakly on 2.4Ghz)

good luck!

The isadora part is the "easy" part, at least once you got the OSC sending. It sounds like you need to start playing with arduinos first. There are some resources here on the forum but a lot of your questions will probably warrant a visit to the arduino forum as well. 

Try the teensy. It can be set to act as a HID or midi interface so that will be very isadora friendly in terms of communication (instead of OSC). The pulse sensor will work fine with the teensy.

here is a guy setting up a accelerometer with the teensy. If you google 'arduino pedometer' there are plenty resources on how to detect steps.

Would you have any thoughts about the pedometer portion of this?

This person here has made an Arduino pedometer. Do you think it would be as simple as adding a wireless component to something like this?

Hi,

The underlying components would very easily be configured to transmit the heart rate data from a sensor like the ‘pulse sensor’ that @fubbi is referring to. I have used a bunch of the same sensors also. Transmitting to OSC is a good option for working with Isadora. It does require or at least it is a recommendation to use a dedicated wireless network device to keep the UDP OSC stream as reliable as possible in performance.

Best Wishes

Would you suggest I dive in

 Yes, you should be able to connect the device @fubbi linked, to a ESP8266 (I have been using the Huzzah), then communicate with Isadora using Art Net (this has been my approach).

Sounds like a fun project :)

NOTE: USB power-banks make for great power sources.

I'm curious: what was your use-case for your heart monitor?

Wow. Thanks for the suggestion of ESP8266.

I'm very new to the world of microcontrollers. Would you suggest I dive in, and see if I can get controllers talking to Isadora over WiFi?

@bonemap Those wearables are really something! Would your DanceDanceSense work as a pedometer, do you think?

and there are other ones. And plenty of info on how to connect isadora and arduino here on the forum.

In a nutshell I would say its realiable enough to monitor a pulse this way. there will be dropouts but if your average over time its fine.

First, I deleted your cross-post. It really isn't necessary in our forum to cross post since most users check the recent/or unread view.

So, a few users have worked on wireless microController based feedback systems.
The one that comes to mind right away was something @bonemap pointed me toward sometime back. Perhaps he can share a link/details again.

One micro controller I know has been used (I have used as well) is the based on ESP8266
This search brings up a few interesting forum posts. (I think I see Bonemaps in there as well)
