13章 デジタル入力Motors
この章では、スイッチやキーパッドなどのデジタル部品を使うレシピを紹介する。また、デジタル出力を持つモジュールを、Raspberry Piの汎用入出力（GPIO）ピンに接続する方法も説明する。
多くのレシピでは、ハンダ付け不要のブレッドボードと、ジャンパー線を使う必要がある［レシピ10.9を参照］。
レシピ13.1：押しボタンスイッチを接続する
●課題 スイッチをRaspberry Piへ接続して、それを押すとPythonのコードが実行されるようにしたい。
●解決 スイッチをGPIOピンへ接続し、Pythonプログラムの中でgpiozeroライブラリーを使ってボタンが押されたことを検出する。
このレシピの製作には、以下のものが必要だ。
- ブレッドボードとジャンパー線（付録Aの「プロトタイピング用の器材とキット」を参照）
- 押しボタンスイッチ（付録Aの「その他」を参照）
図13-1に、ブレッドボードとジャンパー線を使って押しボタンスイッチを接続する実体配線図を示す。
