Usage
-----

### arduino_ir_remote command


    % arduino_ir_remote --help
    % arduino_ir_remote --list

Read IR Data

    % arduino_ir_remote --read tv_on

Write IR Data

    % arduino_ir_remote --write tv_on



### Rubygem

Connect
```ruby
require 'arduino_ir_remote'

ir = ArduinoIrRemote.connect   # use default device
ir = ArduinoIrRemote.connect "/dev/tty.usb-devicename"
```

Read IR DATA
```ruby
ir.read do |data|
  p data
  ArduinoIrRemote::DATA["tv_on"] = data
  ArduinoIrRemote::DATA["tv_on"].save
end
ir.wait
```

Write IR DATA
```ruby
ir.write ArduinoIrRemote::DATA["tv_on"]
ir.wait
```

Read Sensors
```ruby
ir.temp_pin = 0  # set temperature sensor pin

loop do
  0.upto(5).each{ |i|
    puts "[analog#{i}] #{ir.analog_read i}"  # read analog input pin 0~5
  }
  puts "temp #{ir.temp_sensor}"  # read temperature sensor
  sleep 1
end
```


Test
----

    % gem install bundler
    % bundle install
    % export ARDUINO=/dev/tty.usb-devicename
    % bundle exec rake test
