开启蠕动泵继电器x间隔，以毫秒为单位

Question

这是我在arduino中的第一个代码。我试图为我的花园建立一个简单的浇水自动化系统。该代码包含3个主要功能，即：

1. 将水倒满肥料箱。
2. 在此过程中，将假设肥料混入的水补充到水箱中的同时，向水箱中添加肥料。
3. 要全天进行自动浇水。

对于第一和第三功能，我认为我已经完成了它（理论上是小型系统）。哈哈！

现在，对于2号肥料功能（fertilizer_PUMP（）），我使用2个蠕动泵将AB肥料溶液添加到水箱中。我试图让泵以x的间隔运行，但是该功能仅运行一次，之后该继电器将不再触发。谁能帮忙并指导我缺少哪些部分？我也欢迎任何改进我代码的建议。。谢谢。

UPDATE：

对此感到困惑，我深表歉意。实际上，对于此功能，以下是我的要求。

1. 如果顶部浮子干了，底部浮子湿了>开启蠕动泵10秒钟（或者以后会改变更多，然后停止。）>
2. 然后，如果顶部浮球干燥而底部浮球干燥>重置。
3. 等待下一个顶部浮子干燥和底部浮子湿。

再次感到困惑，我真的很抱歉。 Kinda以前弄乱了逻辑。

将您的currentTime和肥料_pumpON定义为全局
