Inspiration

For the people that don't have the time to blow on their coffee but also don't have time to waste, this was the perfect product to build. Students are especially busy doing work and multitasking. While they are hard at work, they don't have time to stop and cool down their beverage. This is the perfect solution

What it does

The coffee cooler measures the temperature in degrees Fahrenheit of the coffee (or other hot beverage) and cools it down to the optimal temperature of enjoyment. It does this by sending a signal to the fan that says if the temperature is too high, turn on the fan, and if it gets to the optimal temperature then the fan turns off. This way, we ensure that the beverage is not cooled too much and is not too hot where the drinker doesn't burn his mouth or tongue. Further, there is bluetooth to show the drinker how hot the drink is while they are working.

How we built it

We built it by using a motor with a fan, a DHT 11 sensor, a fan, and a relay. Code was used from the DHT11 sensor library on the Arduino IDE and code was written by us to make the fan turn on and off based on temperature boundaries from the DHT. Further, a Bluefruit LE UART Friend and its corresponding app (Bluefruit Connect) was used to monitor temperature on our phones. Separate code was added to this which connected DHT data to the bluetooth.

Challenges we ran into

Some challenges we ran into were the code and the bluetooth. It was hard to debug the code because we ran into errors which didn't allow us to receive data from the build to our phones.

Accomplishments that we're proud of

We are proud of learning how to make several parts work together and to see through our dreams into reality.

What we learned

We learned that although techniques can be learned in the classroom, applying them to the real world is more difficult than it seems. Determination and resilience are key to seeing through a project no matter the scale.

What's next for The Coffee Cooler

This is the end of the line for The Coffee Cooler. Products will not be released after this so make sure to get your hands on one while you can!
