1. A computer mouse comprising:
one or more processors;
a scroll wheel operable to rotate on an axis in a first and second direction;
a braking system controlled by the one or more processors and operable to provide a braking force on the scroll wheel that stops and prevents rotation of the scroll wheel, the braking system comprising:
an engagement mechanism; and
a piezoelectric device controlled by the one or more processors and coupled to the engagement mechanism,
wherein in response to an applied voltage, the piezoelectric device bends and pushes the engagement mechanism from a first position, where the engagement mechanism does not interface with the scroll wheel, to a second position where the engagement mechanism interfaces with the scroll wheel and provides the braking force.
