When you have mastered the default playing mode (decimal conversion),
you may like to challenge yourself to convert from hexadecimal notation to
binary. In hexadecimal mode, your Binary Blaster will display the values 10-
15 in hexadecimal. Note, the lower values (1-9) will still be shown as
decimal values, because these are the same in both value notations.
HexadecimalMode
To play in Hexadecimal mode, follow these three steps:
(1) Turn your Binary Blaster off.
(2) Press and hold the "BIT 0" button.
(3) While continuing to hold the "BIT 0" button, turn your Binary Blaster
back on again. You should see the display show "A b C d E F". You are
now in hexadecimal mode. To go back to default decimal mode, simply
cycle power without any buttons pressed.
Here is a hexadecimal chart to help you get started:
"1" = 0001
"2" = 0010
"3" = 0011
"4" = 0100
"5" = 0101
"6" = 0110
"7" = 0111
"8" = 1000
"9" = 1001
"A" = 1010
"b" = 1011
"C" = 1100
"d" = 1101
"E" = 1110
"F" = 1111
We hope you enjoy your Binary Blaster. After a bit of practice, please feel
free to post your best score in the discussion area of this tutorial. Thanks
for your support of SparkFun and have fun blasting binary values!
Troubleshooting Buttons
Is one of your buttons not lighting up? Don't fret, there is an easy way to fix
it! The most common cause of a failing LED is incorrect polarity. We have
designed a special trick into the Binary Blaster PCB to fix this. You can
simply cut the two traces, and close two jumpers. This will swap the polarity
without having to remove the button.
First, find the solder jumpers next to the button you are troubleshooting.
There are two jumpers per button. They are located on the bottom side of
the PCB, near each button.
