Story

I started this project because I couldn't find (on makerworld, printables or thingiverse) a DIY 7-segment digital clock that was aesthetically pleasing for me, so I made my own and I made it smart.

The project unexpectedly received more attention than I thought, and thanks to the community feedbacks and advices, i'm adding new features to the ESPclock.
