This project was, effectively, my introduction to microcontrollers. I was rather short on time, though, for this (it was a Christmas present, after all), so I’ve had to wait until after the fact to write about it. So, this is a long post.
The idea is that, inside of a frosted plexiglass cube, there’s an accelerometer, a microcontroller, and a few RGB LEDs. As the cube is tilted, it glows different colors. Each axis from the 3-axis accelerometer controls the brightness of each color component in the LEDs. Prior to doing this, I hadn’t had any experience with microcontrollers beyond knowing what they are, so I had a fair amount to learn.
