Wow a raspberry pi to control light? That sounds really interesting! Tell me more about it.

Some smart light bulbs, such as the Philips Hue series, provide an API which the Raspberry Pi can interface with using an appropriate library (e.g. `phue` for Python). With enough programming skill, you could set your Raspberry Pi up to slowly turn on the lights in the morning for a gently awakening, or let you control the lights using your voice thanks to software like Mycroft. You can also connect non-smart light bulbs to your Pi using a power relay.

How would my pi connect to the bulbs? Is it by wifi or Bluetooth or something?
