BUILD IT YOURSELF
Recently, I built a number of digital clocks in various configurations. Flashing LEDs
have always interested me since I made my first digital clock many years ago with
about 20 7400 series integrated circuits and red seven-segment outputs. My last
digital clock displayed the time in different colored LEDs representing binary
numbers for output. This got me thinking about an even more elaborate version —
one with a matrix of 32x32 LEDs.
