Cylon robot with two LEDs and a Basic Force Sensing Resistor

acb-cylon.coffee

fs = require('fs')

isUSBModem = (element) ->
  element.match(/^cu.usbmodem\d+/)

device = fs.readdirSync('/dev').filter(isUSBModem)[0]

Cylon = require('cylon')

  name: 'acb-cylon'

  connection:
    name: 'arduino', adaptor: 'firmata', port: '/dev/' + device

  devices:
    [
      { name: 'green',  pin: 12, driver: 'led' },
      { name: 'red',    pin: 11, driver: 'led' },
      { name: 'button', pin: 2,  driver: 'button' },
      { name: 'sensor', driver: 'analogSensor', pin: 0, lowerLimit: 200, upperLimit: 400 }
    ]

  work: (my) ->
    my.button.on 'push', ->
      console.log('button!')
      my.red.toggle()

    my.sensor.on 'lowerLimit', ->
      my.green.turnOff()

    my.sensor.on 'analogRead', (val) ->
      if val > 0
        console.log(val)

    my.sensor.on 'upperLimit', (val) ->
      my.green.turnOn()

Cylon.api(host: '0.0.0.0', port: '5432')

Cylon.start()

I had to patch the Robot.prototype.requireDriver in node_modules/cylon/dist/robot.js in order to use multiple LEDs.
