Synchronizing

The biggest challenge we faced at this stage was synchronizing the horn motion of the two paired devices. There was always a slight lag between the two devil devices, and even though their known environment stayed constant their behaviors were inconsistent. We were able to improve the consistency using delay time on the code as well as maneuvering the pressure sensor in a certain way that it would activate the Servos at the same time. Through numerous iterations, this motion performance improved significantly over time.

User Feedback

After we built the first prototype, we went around to interview potential users for feedback. As we expected, the quirky, snappy motion of the horns was received positively, although at the time of this feedback session we were still having challenges deciding on the use case to target.
