Arduino Infinity Mirror - 3rd Year (2017)

This was a week long workshop consisting of learning the basics of Arduino, and also completing a basic project.

Our team decided on designing an infinity mirror, that changes color depending on temperature. We also made it energy-saving by adding proximity sensors. Using these meant that the led-strip will only light up when the person is within 1 meter from the mirror.

We used blue as an indicator for cold weather, green for optimum temperature, and red indicating hot weather.

I added in a quick video, explaining and showcasing the project.

Enjoy.
