Authored by:

Year in Program:
2016-2017
Designed For:
HS Students
Overview
Students, in groups of three, are building and operating a system that controls the reflection of a stationary laser beam which is redirected onto a glow in the dark projection screen using mirrors mounted on two servo motors. The servo motors, being used to control horizontal and vertical movement of the laser beam, are controlled by student programs uploaded to an Arduino microcontroller. Students plan the pattern they want to make and use trigonometric formulas to determine values to be included in a program controlling the servos.
After completing this module, student should be able to:
- Students will anticipate, design, create, and coordinate safe control of the reflections of a laser beam.
- Students need to apply trigonometric functions to calculate values to be included in programing that result in rotation of servos attached to mirrors which, in turn, control the movement of a reflected laser beam.
- Students need to write a program using C+ to precisely control servo movement.
