## Outcome

The goal of this skills dev was to create an ambient calendar alert, so the neopixel would fade to red 15 mins before a meeting and fade to white when the meeting was over

## The process of working with a neopixel was pretty straightforward in terms of the circuit and code. I had the most difficulty making the light fade in and out, and even now I think I could come up with more efficient code in comparison to what I currently have. Additionally working with the IFTTT was initially confusing because I wasn't sure how to initially set it up, but once I got familiar with the website it was easier.
