LINEBot×obnizで、「赤鼻のトナカイ」「Joy to the world」が流れる仕組みを作ってみた！

Last updated at Posted at 2021-11-08

###「素振りを頑張った君へ」最高のプレゼント！！
素振りの練習を頑張ったあなたへ最高のサプライズプレゼントを用意しました。
LINEから、「素振りの練習終わったよ！」と伝えると返信がきて、サプライズの音楽が流れるシステムを制作しました。

##開発環境
・LINEBot公式アカウント解説
・Visual Studio Code基本操作
・LINEBot参考ページ
・obniz公式ドキュメント（起動とWi-Fi設定）
・obniz公式ドキュメント（Speaker）

##制作物

##まとめ
音階もいちから制作したので、皆さんぜひ使ってみてくださいませ！！！
動画は、早送りしてますが、音楽は、ゆっくり流れます！！
クラッカーを最後鳴らすところまで制作したかったのですが、出来ませんでした！！
次への課題です！
