If you type your number into the Windows calculator in scientific mode, you can click the button below the display that says "Bin" and it will convert it to binary. Your team's binary number is 100110001001.

Or, just start flicking switches from right to left until the number equals your team. Start with them all up, and see what effect each switch has. Teach yourself binary (Base 2).

Quick explanation: Start from the left and work to the right, flipping a switch from 0 to 1 whenever that place value will divide into your number with or without a remainder.

Better explanation:Base ten works by setting each place value equal to 10^n, where n starts at 0 and increases sequentially from there.

Thus, you end up with the following place values in a base 10 number
1000 -- 100 -- 10 ---- 1
10^3 - 10^2 - 10^1 - 10^0

So, to set my team number, 1552, into base 10 let's work from the left to the right. (You should start at the right and work left, but it's easier to think of this way)

In the 1000s place we see that 1552 has 1. In the 100s place we see that 1552 has 5, in the 10s it has 5, and in the 1s it has 2. Simple enough.


In binary (base 2), it's the same thing except that you use 2^n instead of 10^n.

Thus:
1024-512-256-128-64-32-16-8-4-2-1
2^10 - 2^9 - 2^8 ... 2^0
Now, with base 10 you can set each place value to 0,1,2,3,4,5,6,7,8, or 9. With base 2, it can only be 0 or 1.

Thus, setting the dip switches on the OI indicates which place values (in binary) should be set to 0 and which should be set to 1.

To set team 1552, you would set the place values for 1024, 512, and 16 to 1. The number (in binary) for 1552 is: 11000010000
The OI converts this to decimal (base 10) when it displays it on that LED display.

Re: setting the team number for the OI
 

use the powers of 2 starting at one, and add...

it should be:

2048, 1024, 512, 256, 128, 64, 32, 16, 8, 4, 2, 1

In that order, find a way to add up to your team number.
