Inspiration

Coffee is best when it's hot, and you can never have too much.

What it does

The goal of this project is to create a coffee cup to beat all other coffee cups. This cup will be able to detect the temperature of your drink, heat the cup if it gets too cold, and let you know if your cup is almost empty. It will involve a temperature sensor to tell us the how hot it is or if it needs to be reheated, a heating element to do the actual heating, and a cold soul in need of a hot beverage.

How we built it

This project was built using an Arduino Uno with an LCD display, which we attached to the side of a coffee cup. We attached a temperature sensor to the side of the cup in order to get a semi-accurate reading of the temperature of the cup. This temperature was then displayed on the LCD. We also had a switch that was connected to the temperature sensor via Bluetooth to turn on and off the heating element depending on the temperature of the cup.

Challenges we ran into

1. Bluetooth modules kept un-pairing while we were working
2. Heating element was not waterproof, which led to issues in implementation
3. Had some trouble getting our parts
4. Final product was very bulky for a coffee cup, so it was hard to make it visually appealing

Accomplishments that we're proud of

It works! We fixed the problem with Bluetooth ourselves.

What we learned

If something starts smoking, unplug it and never use it again.

How to pair Bluetooth devices.

What's next for Coffee Thingamajig

We could try to move from a mass of wires to a circuit board, to compact the design of this product.

We could also improve the design by getting waterproof temperature sensors and heating elements.
