Everybody here loves binary clocks. So do I, so I made one for myself.

Hey man, I really like your project! I want to make something similar, so it would help if you could share the code that you used. I know this post is from a couple of years ago and the code may be deep in your computer, but it would be a great help! Thank you!

Nice project, congratulations. I wonder how you control so many leds regarding the number of available digital ports in Arduino. Perhaps you could share the connection diagram with us, it would be very useful. A tip: if you could use PWM, you can control the brightness of the leds without additional hardware. I did not understand how you use different resistors between active and inactive leds, once they switch their state over the time.

I used digital pins 0-13 (14), and analog 0-3 (4). That's 18, and I needed 18 LEDs. I can not use PWM on all these pins, so that's a no go. I will upload a picture of how I connected the LEDs, so they shine dim when inactive.

I like how you used the old jewelry box. It's useful, and a great conversation piece.

I bought the wooden box in an arts and crafts store and used some wood glaze on it.
