One of the main functionalities of the clock will be… suprise surprise, keep track of time!
For this task we’ll interface with a DS1307 RTC using the RTClib. You can just include that library and forget how it works. But that’s not the way this blog works. Let’s dive a little deeper.
How arduino RTClib works

Back in business, I am alive and well, and working in an embedded software company.
For Christmas we play “secret Santa” with my family, and this year I was going to take the crown home with me. We only have one rule, and this is: “you have to do it yourself”.
I had some spare parts from past projects (or tinkering) and a rough idea of what to do: a calendar clock. And here we have the first post describing how I created the clock.
This post is just the overall design. Kind of an overview of what the clock will do, for more “meaty” content stay tuned, I plan on writing posts about each aspect:
- Wiring the DIY clock.
- A 3×3 font for LED matrix displays.
- Programming the DIY clock.
Casing the DIY clock.
- Arduino and tinyRTC
- Arduino and 4 led matrices
- Arduino clock software
As you can see, I am mostly software oriented (as usual :-D)
