Autonomous Pulse Sensor

thingiverse

I joined a Kickstarter campaign to fund the pulse sensor (http://pulsesensor.com/). Upon receiving it, I was thrilled but thought of creating an autonomous heart rate monitor. To accomplish this, I incorporated a Nokia 5110 LCD into my Arduino; you can get these from Sparkfun, Adafruit, or eBay. After coding, I had a sophisticated heart rate monitor with text and graphics. To enhance its appearance, I designed a case in Sketchup, which I'm sharing today. Additionally, I included the Arduino code, based on the pulse sensor creators' code and Adafruit's Nokia 5110 library (https://github.com/adafruit/PCD8544-Nokia-5110-LCD-library). For those without an LCD screen, a TV Out variant is available; you'll need the TV Out libraries from http://code.google.com/p/arduino-tvout/. Follow the provided instructions for assembling and enjoying your new heart rate monitor.
