When you touch the TOUCH PLATE wires, the LEDs start flashing in a similar manner to a dice rolling over and over. This gradually slows down to rest and a number is displayed exactly like the spots on a XXXXXXXis circuits use LM555 and XXXXXXXXX’s very fun![LED骰子.gif]()

翻译：当你触摸触控板线，骰子的指示灯开始以类似闪烁的方式一遍又一遍的滚动。逐渐变慢直至停止，显示酷似骰子上数字的点。一个XXXXXXXis电路用LM555和XXXXXXXXX很好玩
