signal to amplifiers
Amplifiers power
piezoelectric materials
Piezoelectric materials bend,
reflecting the laser at the proper
angle

Laser mounted on pan/tilt servo motors
Arduino powers the pan and tilt servos,
which move according to which light sensor
is hit by the laser
Output laser is displayed on the map
