寝れない夜のお供が欲しい
みなさんは暑がりですか？それとも寒がりですか？
私は極度の暑がりです。
夏は冷房がないと寝付くとこすら困難だ。
そんな暑くて寝れない夜に暑い歌を流して眠りの手助けをしてもらおう。
そこで選んだ曲が加山雄三さんの「海その愛」だ。
完成品
1分おきに気温を確認して音楽を流してくれる。

まずObnizに「海その愛」を流させる
Obnizから音楽を流すためには一音一音入力しないといけないという非常に地味な作業に入る。
まず楽譜の確保からだが、すべて有料であった。金は払いたくない。
そこで楽譜@ELISEのサンプルの合間を見ながら楽譜を完成させた。
しかし、楽譜が読めない。
そこで【楽譜が読めない人必見】楽譜の読み方をお教えします！と音階と周波数の関係（平均律一覧表）の二つのサイトを駆使して、Obniz 1Y用のヘルツ楽譜を作り上げた。
この１フレーズを完成させるのだけでも一苦労。大変だから今回は「海よ俺の海よ～ 大きなその愛よ～」だけ流れることにする。
こんないい歌を1フレーズだけ流すのは逆に冒涜だった。
熱帯夜だけ流させる
安眠しているときには流れないようにしたいので、暑くて寝れない熱帯夜にだけ流れるように設定する。
そのためには高精度IC温度センサ LM60BIZを使って25度以上の時にだけ音楽が流れるようにNode-Redで設定する。

結論
余計寝れなくなった。1分おきに流れる音楽に気が狂いそうになる最悪の結果に。
当初の予定とは逆の結論に至ってしまった。出来たら意外と何とか実用できると思っていたが、その予想が外れることになるとは思わなかった。
