“Hello reader,
What you can see in the pictures, is my little binary alarm clock, that displays the time using 18 individually adressable RGB LED’s.
I originally planned to build a “normal” clock that uses Led’s as it’s hands. Unfortunately I did not have 60 adressable RGB LED’s at hand. Sooo, what do you do when you want to display a number with as few LED’s as possible?
You go binary, and that is exactly what I did.
The result is this rather interesting looking little alarm clock and today we are going through all of the steps needed, to build one yourself. On the way we are also going to learn to read binary numbers.”
