    This Processing sketch receives the serial data from the HC-05 Bluetooth modem, and graphs it in real time.

    The MCU performs 10-bit measurements at a rate of 50ksps, and averages the result to obtain a 12-bit value. The PC receives a data point once every two milliseconds, which provides plenty of x-axis resolution.

    After 12 hours of programming, and excessive amounts of coffee, I think the data shows a heart arrhythmia.
