/*********************************************************************************
* This code sets the valve motor to a pwm of 0.8. It also sets interrupts for the
* hall sensor input, so on each rising and falling edge, LED1 is flipped, testing
* the ability of the mbed to accurately detect the hall sensor reading. Lastly,
* this code configures the BNO055 and prints the yaw, pitch, and roll to a PC
* terminal.
