Binary Clock

A basic binary clock built using Processing.

Reading the Clock

The clock has a different colored row for each different reading of:

• Year (last 2 digits)
• Month
• Day (of the month)
• Hour
• Minute
• Second

For each row, using the lit up dots as 1's, and unlit dots as 0's, you read the row as a binary number, which represents the value of the row. For example:

• The year row is 010100, which translated to base-10 is 20, for the year 2020
• The month row is 1100, which translated to base-10 is 12, for the month of December
• The day row is 11100, which translated to base-10 is 28, for the 28th of the month
• The hour row is 001011
  • This is 12-hour format; the left-most dot is the AM/PM tag, and the rest of the digits represent the hour. In this case, with the PM light off, and the binary 01011, the hour would be 11, or 11 AM.
  • See below for the 24-hour format
• The minute row is 010010, which translates to 18
• The second row is 000010 which translates to 2

Over all, the image preview represents the DT:

• 12 December 2020, at 11:18:02 AM

24-Hour Time

The main difference of 24-hour time is that on the hour row, there isn't an AM/PM dot at the end of the row, and it ranges from 0-23 on the row. To toggle 12/24-hour formats, see the configuration below.

Configuration

Colors and the 12/24-hour mode can be changed within the Constraints.pde file.

• BG is the background color of the sketch.
• IS_12_HOUR determines whether to show the clock in 12-hour format (AM/PM) or 24-hour format.
• AMPM is the PM light for 12-hour time
• Below AMPM is each time row, and what color they should be
• Don't modify the values below the // END CONFIGURATION // tag. These are for calculating active and inactive colors for the clock lights.
