このライブラリは8*8dotmatrixLedの輝度を階調制御します。 8*8dotmatrixLed以外でも8個のＬＥＤを１組にしたものを１組から８組まで制御できます。 LEDの階調制御は、ON,OFFの指示で輝度を0から100％まで１秒かけて変化させることができます。 それ以外にも、輝度を直接指示することもできます。 This library is the brightness of the tone controls 8 * 8dotmatrixLed. You can control up to eight pairs of those in one set of eight pairs in the LED than 8 * 8dotmatrixLed. Tone control of the LED, ON, can be varied over a second from 0 to 100% brightness at the direction of OFF. Besides this, the intensity can be directly ordered.
