Temperature-Sensing Coffee Coaster

Coffee is taken very seriously here at Digilent, as it is in most workplaces. Something that used to make me mad was not knowing when my coffee hit that perfect “Goldilocks” temperature zone where it didn’t burn my mouth but was warm enough to fully enjoy. I am currently working on developing a thermocouple Pmod using Analog Devices MAX31855 and thought of a great application project. If I could somehow sense how hot the temperature of the coffee was, I could have a microcontroller tell me when my coffee hit the perfect temperature range!
