Cwik Clock v1.0 - An Arduino Binary Clock

Step 5: Prototyping the Display

It's time to hook up the resistors and LEDs to the Arduino. Remember, when uploading your program to the Uno, pin 0 must be unused or you will get a very ambiguous error message.  Since we use it in our circuit, unplug the lead, upload, then replug the lead.

You can see the clock in action in the following video. Please note, I've sped up the clock so that a minute passes in less than 1 second.
