Can Arduino and coin motors achieve tactile apparent motion with a 50ms Stimulus Onset Asynchrony (SOA)?

Can an Arduino-driven system with coin motors produce a reliable illusion of motion at a 50ms Stimulus Onset Asynchrony?

Possibly, but challenging. Small coin motors have activation/braking times (~20-100ms), making a precise 50ms SOA difficult. A piezo sensor can measure *actual* vibration onset, providing feedback for software compensation to improve timing accuracy. The limitation is primarily the motor's mechanical inertia, not the Arduino's digital control. For reliable 50ms SOA, consider faster actuators like piezo buzzers or voice coils.
