ディップスイッチによるアドレス計算

2進数くらい計算すればいいじゃんと言われそうですが、
ぱっと計算して試せるプログラムをProcessingで書いてみた。
数字の下の■をクリックすると、on / offをトグルして計算される。

final int NUM_LEDS = 150;

RectButton rect1, rect2, rect3, rect4, rect5, rect6, rect7, rect8, rect9;//, rect10;

  smooth();

  rect3 = new RectButton(60, 40, 10);
  rect4 = new RectButton(80, 40, 10);
  rect5 = new RectButton(100, 40, 10);
  rect6 = new RectButton(120, 40, 10);
  rect7 = new RectButton(140, 40, 10);
  rect8 = new RectButton(160, 40, 10);
  rect9 = new RectButton(180, 40, 10);
  //rect10 = new RectButton(200, 40, 10);
