/* Button for Keyboard (Arduino Leonardo only) */ | |
/* | |
Button | |
Turns on and off a light emitting diode(LED) connected to digital | |
pin 13, when pressing a pushbutton attached to pin 2. | |
The circuit: | |
* LED attached from pin 13 to ground | |
* pushbutton attached to pin 2 from +5V | |
* 10K resistor attached to pin 2 from ground | |
* Note: on most Arduinos there is already an LED on the board | |
attached to pin 13. | |

This was a huge help! It was the clearest example of button states I could find.
