HelloNerves

• Weather.Forecast.run means getting "http://api.openweathermap.org/data/2.5/weather?id=#{city}&lang=ja&units=metric&appid=#{appid}".

Targets

Nerves applications produce images for hardware targets based on the MIX_TARGET environment variable. If MIX_TARGET is unset, mix builds an image that runs on the host (e.g., your laptop). This is useful for executing logic tests, running utilities, and debugging. Other targets are represented by a short name like rpi3 that maps to a Nerves system image for that platform. All of this logic is in the generated mix.exs and may be customized. For more information about targets see:

https://hexdocs.pm/nerves/targets.html#content
