「Arduino Nano」と「M5Stack用RGB LEDユニット」を使ってサイコロの代わりになるものを作る

はじめに

以前Arduino Nano Everyを使ってサイコロの代わりになるものを作りました。

今回は同じArduino Nano Everyに「Grove Shield for Arduino Nano」「M5Stack用RGB LEDユニット」「M5Stack用メカニカルキーボタンユニット」を組み合わせて改良しました。

出来上がり

はんだ付けは必要ありません。

今回はLEDの制御に「Adafruit_NeoPixel」というライブラリを使いました。

以前、別の工作で「M5Stack用メカニカルキーボタンユニット」を使った時には「FastLED」というのを使いました。
