Temperature Ranking
Paper coffee cups generate a massive amount of trash every year. As more and more people search for an alternative to the throwaway cup, the reusable travel mug selection has increased. Travel mugs can also keep your beverage warm for longer than a paper cup. In this project, you will use a Thermocouple Phidget to determine which travel mug keeps your beverage the warmest.
Setup
Before getting started, make sure you have the following parts.
VINT Hub
Flathead Screwdriver
Step 1
Attach Thermocouple Phidget to the VINT Hub and VINT Hub to your computer.
Connect the thermocouple wires to the Phidget with a screwdriver (red = +, white = -).
Step 2
Optional, boil water and pour it into the cups, this will give the liquids time to cool.

- Run code. The temperature is recorded when the enter key is pressed.
- Record the temperature of 5 students' hands by having each student hold the end of the thermocouple for a moment then record the temperature.
- Pour hot water into 5 different cups, wait 15 minutes, and then measure the temperatures of each of the liquids using the thermocouple.
- Run code, Temperatures are recorded when the enter key is pressed.
- Record the temperature of 5 students' hands by having each student hold the end of the thermocouple for a moment then record the temperature.

- Run code, Temperatures are recorded when the button is pressed.
- Record the temperature of 5 students' hands by having each student hold the end of the thermocouple for a moment then record the temperature.
- Pour hot water into 5 different cups, wait 15 minutes, and then measure the temperatures of each of the liquids using the thermocouple.
Practice
- Add an array to record 5 different temperatures. Your program should exit after 5 temperatures have been recorded (user pressed enter 5 times).
