I started work on a binary clock. I found some code by Dennis Cwik and tweaked it to be able to rapidly advance the time as a crude way to set the clock. What I don’t like about this build is it is using all the digital outs. I think I will rewrite it to use addressable LEDs instead. That will only use one digital out and I can do so much more and look better as well. But for now, here’s what I have.
