RubicでGR-CITRUSのmrubyプログラミング事始め５[インターネット鳩時計編]

Posted at

この回で「RubicでGR-CITRUSのmrubyプログラミング事始め」は最後です。
今までのことを踏まえインターネット鳩時計を作ります。

#動作
動作は単純に

  • 起動時、NTPで時刻を取得
  • GR-CITRUSの時計を設定
  • １時間ごとに時刻のMP3ファイルをしゃべる

としたいと思います。単純！

#今回使うもの

  • GR-CITRUS
  • WA-MIKAN
  • MicroSDカード
  • 圧電素子かスピーカー
  • ブレッドボード
  • ブレッドボード・ジャンパーコード（オス－ワニグチ）×適当

#音声集め
まずは、時報の元となる音声素材を集めます。
以下のようなフリーで提供しているソフトやサイトがありますので利用させていただきます。

学術研究目的ならばNICTの杉浦孔明さんが開発されたrospeexなんていうのも試せます。

K. Sugiura, Y. Shiga, H. Kawai, T. Misu and C. Hori: "A Cloud Robotics Approach towards Dialogue-Oriented Robot Speech," Advanced Robotics, Vol. 29, Issue 7, pp. 449-456, 2015.

有料のものならもVOICEROIDいいですね

##音声ファイル作成
上記ソフトを使い以下セリフ用ファイルを用意しました。

ファイル名 用途 セリフ
0.mp3～23.mp3 時報用のmp3 「0時なのです」「15時でおやつの時間です」とか
now.mp3 時報用前置き用のmp3 「現在の時刻は」とか

WA-MIKANのSDカード直下に以上のファイルを保存しておきます。

#スピーカーもしくは圧電素子とつなげる

第2回の時と同じように、GR－CITRUSと圧電素子（またはスピーカー）を接続します。

CITRUSの端子番号 接続先
0 圧電素子またはスピーカーの＋
GND 圧電素子またはスピーカーの―

#Rubicに書き込み
Ruby使いじゃないのでにわかですが一応クラスっぽく書きました。
