Step 2: Reading the Clock

Each column of LEDs represents a single digit in a 24 hour clock in binary. If you don't undestand binary you may want to quickly read up on it.

In order to read the clock, the rows (starting from the bottom up) represent the numbers 1, 2, 4, and 8. To read the column, simply add the values that are lit up for the column.
