This project in development

Serial module.

defmodule Typehero.RoomChannel do
  use Phoenix.Channel

  def join("rooms:lobby", message, socket) do
    {:ok, serial} = Serial.start_link

    Serial.open(serial, "/dev/cu.usbmodem1411")
    Serial.set_speed(serial, 9600)
    Serial.connect(serial)
    {:ok, socket}
  end
end

defmodule Typehero.RoomChannel do
  use Phoenix.Channel

  def join("rooms:lobby", message, socket) do
  ...
  end

  def handle_info({:elixir_serial, serial, data}, state) do
  cond do
    data =~ ~r/1/ -> broadcast state, "arduino:finger", %{finger: 1}
    data =~ ~r/2/ -> broadcast state, "arduino:finger", %{finger: 2}
    true -> nil
  end

  {:noreply, state}
end

Listen to the channel on that event.

channel.on("arduino:finger", ({finger}) => this.fingerPress(finger))

Tracking differences between different Phoenix versions?

Easy-peasy with Phoenix-diff!
