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
