every time.
You must now press the binary equivalent on the four buttons. Here is a
chart to help you get started:
"1" = 0001
"2" = 0010
"3" = 0011
"4" = 0100
"5" = 0101
"6" = 0110
"7" = 0111
"8" = 1000
"9" = 1001
"10" = 1010
"11" = 1011
"12" = 1100
"13" = 1101
"14" = 1110
"15" = 1111
Here's a few examples to help show how the buttons work.
Example 1:
If you see the number "1" on the display, then you must press the binary
equivalent, which is "0001". This means that you must press the "BIT 0"
button (this is the button furthest to the right). You must also leave the other
three buttons alone (don't press them!) In this way, you are setting only the
"BIT 0" (aka making it a "1" instead of leaving it a "0").
Example 2:
If you see the number "2" on the display, then you must press the binary
equivalent, which is "0010". This means that you must press the "BIT 1"
button (this is the middle-rightside button). In this way, you are setting this
bit (aka making it a "1" instead of leaving it a "0").
Example 3:
If you see the number "5" on the display, then you must press the binary
equivalent, which is "0101". This means that you must press the "BIT 0"
and the "BIT 2" button at the same time.
If you do not press the correct value within a few seconds, the Binary
Blaster will time out, and this effectively means you have lost this round. To
start another, simply press any button.
When you press the correct binary equivalent, then you will move on to the
next random value. There are 15 total. Once you convert all 15 (without
timing out) you have won!
Each time you begin a new game, the order will be different. It does this to
help encourage learning conversion rather than muscle memory of a
pattern. Also, when you have completed all 15 possibilities, the display will
show you your "score". This is the amount of seconds it took you to
complete the game. As you practice your conversions, you should be able
to get this number lower and lower. Good luck!!
