I had so many troubles with the last hardware that I bought a new Bluetooth board. The previous microcontroller was a retired model that may have been a factor. The new one was an Adafruit Bluefruit LE with an ATMEGA 32u4 processor and a Nordic wireless chip. When I didn't see the exact board name in the Arduino IDE, I loaded an example program with the Arduino Leonardo profile that recognizes the same chip. This loaded, but there were problems when I had to start the Compile/Upload sequence and press the RST button five seconds later. I don't know if that will get any better.
Two motors on the new hardware

Now that I could upload code, I reprogrammed the pin numbers to match the new microcontroller. The Bluefruit LE didn't have an onboard LED, and I didn't add one. I did add a second vibrating motor that might have been a 5V model because I couldn't get any motion out of it. I had no trouble communicating with the IMU, so the mix of the code, IMU, and small vibrator made for a usable prototype running in my pocket as I write this journal.
