Arduino uno Arduino按钮和led程序

“我正在尝试制作一个程序，其中我通过一个按钮控制6种模式，问题是，在SOS例行程序之后，例行程序将永远持续下去，直到我将其与SOS的最后一个S完美计时时，才会遵守按钮的按下。下面是一个程序，请解释一下我如何在按下一个按钮后摆脱常规

第二，这个程序可以转换成.hexfile吗？对于PIC12微控制器？ 当做 法瓦德”

更频繁地使用

digitalRead

在每个“SOS”字母的中间和末尾添加一个按钮验证例程，以清除

ledMode

比如：

不，你的建议不起作用……可以通过类似的案例基础来实现吗？

// Uses button presses to switch an LED between off, dim, medium, high brightness & SOS.
