Tessel Button

A tiny ~2kb library to provide higher level events allowing advanced options via user input with the config button. In addition it provides visual feedback (LEDs) to the user to make counting easier.

Note: The purpose of the button may change in the future.

``bash
npm install tessel-button --save
`

`js

var button = require('tessel-button');

// Hold Count Event
button.on('hold', function(count){
console.log("HOLD COUNT", count);
switch(count){
case 1: flushLogs(); break;
case 2: checkWifi(); break;
case 3: clearLogs(); break;
case 4: reset(); break;
default:
break;
}
});

// Quick Tap Event
button.on('click', function(clicks){
console.log('CLICK COUNT', clicks);
});

`

You should see the pattern.

$3

#### button.hold_duration

Default: __500__

This option controls the time that needs to elapse before the hold count is incremented.

#### button.click_timeout

Default: __300__

The time in between presses in order for a group of clicks to count. This value should be lower then button.hold_duration.

$3

#### hold

add an event listener onto the button. Returns the hold count.

`js

button.on('hold', function(count){

});

`

#### click

add an event listener onto the button. Returns the click count.

`js

button.on('click', function(count){

});

`

I have notice bizarre behavior when registering multiple listeners on the button press and release` events. Haven't had time to research it deeper. I believe there maybe an issue inside the firmware.
