有一個(gè)撞塊，5個(gè)開(kāi)關(guān)。
兩個(gè)極限開(kāi)關(guān)：左極限、右極限；
中間3個(gè)開(kāi)關(guān)：1、2、3
撞塊在左右極限開(kāi)關(guān)之間靠風(fēng)崗隨意走動(dòng)、隨意停下。（不用考慮用什么電磁閥。）

設計一個(gè)程序：   A、怎么確定撞塊走到哪個(gè)位置？
                 B、撞塊走到一個(gè)位置停下后(假設走到開(kāi)關(guān)1和開(kāi)關(guān)2位置之間，1、2都沒(méi)接通)，記住現在的位置，根據項目要求，從現在的位置產(chǎn)生別的動(dòng)作。

有興趣的朋友可以做下，大家學(xué)習學(xué)習
