motorTrial.ino was created as a proof of concept that an Arduino can send the right signals to the ESC to keep a brushless motor running. (based on this

Using this code, the Arduino accepts potValue = 51 all the way up to potValue=255. This corresponds to

motorGrav.ino listens to a Unity environment for the letter ‘A’ and keeps the motor running at a constant speed when this happens, similar to the initial sections of GyroVR. In this case, the user should feel a resistive torque about the pitch axis as they rotate their head about the yaw axis.
