Here's a tip: For reading a binary clock, you can think of it as this:
00 0000:000 0000:000 0000
For example, if it's 12:45:00, then you will do:
01 0010:100 0101:000 0000
Those who need a quick explaination of how binaries work, start with 1 from the right and multiply by 2. For exampke, let's say that you have 8 zeros. "0" means "off," and "1" means "on." This is known as bit. 8 bits equal to 1 byte. So let's put into 8 zeros.
00000000
All zeros indicate that each of the 8 bits are off. Now, let's say that you have:
11111111
That's 255. It does this in a following order:
128 + 64 + 32 + 16 + 8 + 4 + 2 + 1 = 255
Let's break it down:
128 + 64 = 192
192 + 32 = 224
224 + 16 = 240
240 + 8 = 248
248 + 4 = 252
252 + 2 = 254
254 + 1 = 255
Hope this helps. You don't have to be a geek once you understand about what binary is.
