Be still my beating heart

Another project on the agenda turned the Rigado board into a heart rate sensor that beams its data out over Bluetooth. The heart rate data in the demo is gibberish, but serves as a good illustration of what you can send to a Bluetooth smartphone app. Seminar participants have to bring a smartphone and download an NXP app that works with the demos. In the case of the heartrate sensor demo, participants pair the Rigado heart rate sensor with their phone app. They can then see the gibberish heart rate on the smartphone app as it updates.
