# BlinkM
For this example, we're going to use the `cylon-firmata` module to blink a light
using BlinkM.
Before we start, make sure you've got the `cylon-firmata` module installed.
First, let's import Cylon:
Cylon = require '../..'
With Cylon imported, we can start defining our robot.
Cylon.robot
Our robot will be using an Arduino, and communicating over the Firmata protocol:
connection: { name: 'arduino', adaptor: 'firmata', port: '/dev/ttyACM0' }
And we'll have one device, a BlinkM led.
device: { name: 'blinkm', driver: 'blinkm' }
We'll now set up our robot's work.
work: (my) ->
When the BlinkM sends the 'start' event, we'll set up our events
my.blinkm.on 'start', ->
We'll request the BlinkM's version, and print that to the console:
my.blinkm.version (version) ->
console.log "Started BlinkM version #{version}"
By default, we'll turn the LED off and assign a boolean that we'll use to
determine if it's on or not:
my.blinkm.off()
lit = false
Now, every second, we'll toggle the LED, using the `lit` variable to determine
which state we need to transition the BlinkM to:
every 1.second(), ->
if lit
lit = false
console.log 'on'
my.blinkm.rgb 0xaa, 0, 0
else
lit = true
console.log 'off'
my.blinkm.rgb 0, 0, 0
Now that our robot knows what to do, let's get started:
.start()
