STATE TRANSITION DIAGRAMS
OVERVIEW
The SmartScreen and oral B Braun toothbrush reacts to the immediate environment within a
predefined maximum time interval. The specifications as listed in the report section demonstrate
the functional and temporal behavior of the toothbrush and SmartScreen. The MATLAB R2017a
was used to demonstrate the State Transition Tables as required in the assignment. The attached
video describes the State flow and it represents how the toothbrush works in connection to the
system.
