I found a USB↔Serial converter in my stuff, but it wasn't one I used before, and it was an eBay cheapy, so it was a gamble that paid off when it worked. I got lucky. The pinout on the converter was not the typical arrangement, so I had to map which wires were coming off the Arduino and their order. Even after that, I got them backward. As a test, I downloaded the BLINK program and renumbered it to activate the motor instead. After a moment, the movement vibrated a wire off, and I had to solder it back.

I saved a new copy of the code and commented out all the Bluetooth code and did my best to send that information to the serial port instead. It may not be useful, but it shouldn't hurt at this stage. When I uploaded the code, the only reading that came through was -000.006 degrees. Then I tried the example code, and it reported that it couldn't find the sensor board. I looked online and found David Pilling, who advised shorting the data type pins and grounding the "I2C" via. This time I got a reading!
