PURPOSE 
This project introduces advanced programming with sensors and can also be used to teach linear equations.

DESIGN CHALLENGE
Create a musical instrument that uses a sensor to play tones.

DIFFICULTY LEVEL
Building: Beginner – no prior experience necessary
Programming: Medium – uses a mathematical formula to make sounds from sensor readings

MATERIALS
LEGO MINDSTORMS EV3 kit

DETAILED OBJECTIVE
Write a program that:

• Takes a measurement from sensor data
• Uses data operations to scale the measurement
• Plays a tone with scaled measurement as frequency
• Uses a loop to repeat program
