# Raspberry Pi - Button
|
||
|
|
|
||
|
|
For this example, we're going to toggle a LED every time a button is pressed.
|
||
|
|
Both of these devices will be hooked up to a Raspberry Pi.
|
||
|
|
|
||
|
|
Before you get started, make sure you have the `cylon-raspi` module installed.
|
||
|
|
|
||
|
|
First, let's import Cylon:
|
||
|
|
|
||
|
|
Cylon = require '../..'
|
||
|
|
|
||
|
|
With Cylon imported, we can now start defining our robot.
|
||
|
|
|
||
|
|
Cylon.robot
|
||
|
|
|
||
|
|
Our robot has one connection, to the Raspberry Pi the hardware will be running
|
||
|
|
on. For hardware, we're keeping it simple. A LED on pin 11, and a button on pin
|
||
|
|
7.
|
||
|
|
|
||
|
|
connection: { name: 'raspi', adaptor: 'raspi' }
|
||
|
|
|
||
|
|
devices: [
|
||
|
|
{name: 'led', driver: 'led', pin: 11},
|
||
|
|
{name: 'button', driver: 'button', pin: 7}
|
||
|
|
]
|
||
|
|
|
||
|
|
With the hardware defined, we can get to the work our robot will perform. And as
|
||
|
|
you can see, it's enormously complex:
|
||
|
|
|
||
|
|
work: (my) ->
|
||
|
|
my.button.on 'push', -> my.led.toggle()
|
||
|
|
|
||
|
|
Essentially, when the robot's button emits the 'push' event (when it's pressed),
|
||
|
|
the LED will be told to toggle.
|
||
|
|
|
||
|
|
And voila! We now have a basic light switch. All we need to do now is tell the
|
||
|
|
robot to start:
|
||
|
|
|
||
|
|
.start()
|
