Heart Rate in processing.org

[Robby Balona]

Hi Guys

With my limited knowledge, I have worked out how to send a heartbeat to the watch from processing.org. All this script does is send random numbers to the heartbeat screen .. could be used to show speed or something.

I did it to understand and see if its possible., so excuse the fact that it does not turn off BlueRobin yet. This is with standard firmware and all. Imagine the potential with Raspberry PI, Arduino etc etc

Next version will be in java I think.

Run it and then start Blue Robin on your watch.

Thanks

Robby
