このプログラムはEightDotMatrixLedライブラリのサンプルプログラムです。 このサンプルプログラムは８個のＬＥＤを４組点滅制御しています。 This program is a sample program EightDotMatrixLed library. This sample program to control the LED blinks four sets of eight. 動画回路での点灯制御の説明 １番上の赤色ＬＥＤ(com0)：点灯・消灯を１秒かけてスムーズに行います ２番目の緑色ＬＥＤ(com1)：点灯はスムーズ。消灯は直ぐに行います。 ３番目の赤色ＬＥＤ(com2)：点灯・消灯は１番目と同じ。輝度の上限を右から左に段階的に大きくしています。 ４番目の赤色ＬＥＤ(com3)：輝度データ(gray data)を直接制御しています。 =動画 video = {{http://www.youtube.com/watch?v=aRjSfpSjA30}} =回路図 schematic = {{/media/uploads/suupen/111204exampleschematic.jpg}}
