Arduinoでプログラミングを始めるとき、まずよく行うのが「LEDの点滅」です。LEDを点滅させるプログラムはとても基本的で、Arduinoの使い方に慣れるための練習にぴったりです。 この章では、Arduinoとブレッドボードを使って、LEDを点滅させる方法を学んでいき ...

millisはプログラムの実行を開始してからの経過時間をミリ秒で返します。 while (millis () - old_time_a < 10); 経過時間からold_time_aを引き、10ミリ秒待ちます。 なので上記の場合、LEDは10ミリ秒ごとに1段階上がり、2560ミリ秒で一番明るくなります。 この値を大きくするとゆっくり明るくなります。 もう ...
