Early Steps and Missteps

A project log for Hello Double Bell Clock

Like the hello world of Hackaday, I'm building a clock.

I started with the assumption that I should use what I had, and this caused a few delays.  Specifically I had chosen a Nucleo board as the starting point for this project because I have familiarity with the processor line; but I do not have familiarity with the software.  I quickly discovered that many of the Arduino libraries I had used before were specific to AVR processors.  While many crosses existed there were not enough for me to build a complete project.  I decided instead to purchase an Arduino Nano because it had support for libraries I was familiar with.

At this stage of the project I have working prototype software on the rig pictured below.  The following features are functional, but not fully documented:

  1. A serial parser is written and I can set the time via a computer.
  2. The RTC can be set and tracks time.
  3. Three functions turn the time into animations for the.
  4. Ring displaying the minutes.
  5. The tens digit.
  6. The seven segment display.

A picture of the rig I was able to develop this on is shown below.
