A binary clock for Arduino Uno

Everything you need to know is in the 2 files, but here the parts anyways:

1 Arduino Uno

4 leds of any color

6 leds of any other color

1 led of a third color

11 220Ω resistors

12 wires, I recommend 1 black/blue and 11 red


The clock isn't accuarate enough to run for a long time, but it's a cool anyways ;) have fun

I had the same issue a few years back, if you add an RTC chip it becomes more accurate! :)
