 2 | Teensy code for The Button.

 4 | What is "The Button" exactly? See here:

 8 | You'll need to install the Arduino IDE and the Teensduino add-on.

13 | 
14 | The code allows the Teensy to emulate a space bar when the button 
15 | is pressed, and you can't do it faster than once per half second.
16 | 
17 | In the code, pin 10 is for the button and pin 11 is for the LED.
18 | 
19 | The on-board LED turns on when you push the button. It's for debugging 
20 | more than anything else, but you could wire up an external LED to light 
21 | up if you were so inclined.
