It's about having fun. If you're not having fun, why are you doing it?
very neat.one minor problem, when the screen lock engages, the flash turns off. Unlocking doesn't turn the flash back on, and there isn't an obvious way to restart.thanks for sharing!
No problem. There's a couple of options:You can either disable the application idle timeout or wire up switching the camera capture off and on into the application did become active/application will resign active notifications.The code is a very bare bones demo app so a lot of the bells and whistles are missing.CheersChris
Very, very, very, nice work.Thank you
I was just wondering how you could possible transfer the data from this into an actual measurement of the heart rate, so it actually provides how many beats per a minute??Thanks
A very simple way of counting the heart beats would be to just detect when the trace goes from -ve to +ve and count those transitions over a time period. Each transition corresponds to one heartbeat.
