##### Digital Mood Ring - TI-Nspire CXII Python

Bring science and coding together (no coding experience necessary) while developing a mood ring! The science of color mixing is explored while determining the right body temperature thresholds.

Publisher: Texas Instruments Inc.

Topic:  Physik

Mood Ring Project

Learn about the science of color.

Write a Python program on the TI-Nspire CXII calculator using the TI-Innovator Hub.

Create a feedback and control system.

Students will engage with the following concepts:

Science of Color

Inequalities

Feedback and Control systems

Temperature sensor input

Color LED output

Coding Concepts:

Loops

Conditional Statements

Variables
