このライブラリは１桁から８桁までのSeven segment Numeric LEDを制御します。 LEDはanode commonとcathode common を使用することができます。 LEDの表示は１秒で表示をスムースに切り替えるモードと、直ぐに切り替えるモードの２つのモードを選択することができます。 This library to control the Seven segment Numeric LED 8 digit of 1. You can use the LED cathode common and anode common. Switch mode LED display and a second displayed a smooth, you can choose two modes to switch modes quickly.
