Temperature Sensitive Infinity Mirro

Temperature-Sensitive Infinity Mirror Using Arduino

As per an assignment in my digital multi-media class, I’ve combined two Arduino-related tutorials into a functional object! The result is a pair of infinity mirrors that flash red and blue depending on minute fluctuations in ambient temperature. This is my first experience with Arduino, and my first attempt at building an electronic device from …
