While in a cafe helping my friend with a project, I found that I had a hard time managing my coffee sip intervals. The pacing was also weird because I would have to interrupt the conversation to pick up and drink the coffee.
What if there was a way to adjust my behavior by having an impartial timer indicate when it’s been too long between sips. I used a Circuit Playground Express to prototype my idea. I used a light sensor and the on-board buzzer to indicate when the coffee cup has been in the coaster for over 5 seconds. The buzzer resets once I remove the coffee to drink.
