Color Clock

This is a clock that uses an Arduino microcontroller and Real Time Clock (RTC) to accurately track and display the time using a combination of color and light. The inner ring shows the current hour of a 24-hour day, using a distinct color for each. The outer ring displays minutes solidly using a different color for each quarter. Seconds displays on the same ring using the current hour’s color plus the color of the minute position it’s currently overwriting if that minute is being displayed.

This was the first Arduino project I integrated with my wider design skillset. Despite this, my main focus was on learning Arduino/C++ rather than enclosure design, and I know I could do better if I set my mind to it.
