Students are challenged to design a system that informs the user if their coffee is too hot to drink. The system should notify the user of three states: Too hot to drink; too cold; or just right.

Save your palate

Design a system that monitors coffee to ensure the temperature is just right.



Students create a system that monitors the temperature of a beverage and notifies you when the temperature is too hot or too cold.

Use of TI SensorLinkTM


Feedback and control systems

Vernier Temperature sensor input

Learn to do the project yourself


Step 1: Get a practice kit from the TI STEM Team. 

Go to  Click on the  Get Started Now button. Then fill out the form to begin the conversation with the TI STEM Team.


Step 2: Do the following:

A. 10 Minutes of Code with the TI-Innovator Unit 1.  These are step-by-step instructions that will give you a foundation for creating, running and editing TI-Basic programs with the TI-Innovator Hub. Follow this link. Click on Unit 1 and then click step by step to go through the skill builders. (Note: Units 2 and 3 are also useful.)

B. Digital Mood Ring Project.

We have found this to be a great first project for doing feedback and control systems. The topic is fun and the set-up is not intimidating.

You will cover foundational concepts for programming and for feedback and control systems. After doing this project both adults and students say that the more advanced projects no longer look so overwhelming. 

Make sure to download and follow the “By Challenges” Teacher document and example programs at this link.

Also, we highly recommend a set of YouTube videos that we created based on workshops with teachers preparing to lead summer camps. Follow this link.

C. You are ready for this project. Download the teacher document, example programs and any other files from this page. Work through the challenges in the teacher document.
