Question Details Ok, so want to get a heart rate sensor, take it apart, and adapt it to make it bluetooth enabled so i can see the heart rate on a phone/computer. Where should I start? What hardware and software should I use? I'm really a beginner and have no idea where to start lol. Also, I want to make it so that if both the heart rate and touch sensitive sensors are touched, everything is fine (the circuit is complete?) but if the touch sensitive sensor isn't being touched, that sets off a sort of alarm (on the phone/computer, through Bluetooth). I know this is a big question, but if anyone could please help? Where should I start?
