In this video I create a color changing nightlight based on a famous symbol from one of my son’s favorite video games. Because space was tight, I decided to use an ATtiny microcontroller instead of an Arduino. These are very inexpensive and are a great way to shrinkify your Arduino projects. ATtiny come in multiple configurations (number of pins and amount of memory). One of the most popular is the ATtiny85 which only has 8 pins and is very small.
