Binary Clock
Hello friends.....
here is how you can read binary clock...
here you can see 1,2,4,8 assigned for column.
in the picture you can see in HH section first column first led is on so it is one,second column all led is off so 0 SO HERE HOUR IS 10. Now in MM section two led is on so add the assigned numbers.
in picture add (1+2=3) and add(1+2+4=7) SO MINUTE IS 37. Then second (SS) is 49.
what you need....
Here is the circuit diagram......
