for循环的执行过程可用下图表示: LED逐渐变亮的话应该是这样:for(brightness = 0; brightness <=255; brightness++),在表达式1里面直接给brightness赋值为0,而表达式2和3决定着是否循环。 好了,开始编程:(为了观察方便,这里启用了串口通讯) 上传看一下: ...

当有物体靠近传感器约10cm的位置时,触发中断,点亮LED LIGHT_TIME毫秒,持续触发则常亮,无则灭灯。 通过修改 宏定义 LIGHT_TIME调节延时,LED负极接在数字10口(正极 3.3V供电) 2、靠近点亮/熄灭LED,延时期间操作不响应 当有物体靠近传感器约10cm的位置时,触发中断,点亮/熄灭LED,延时RESPONSE_TIME毫秒,延时期间操作不...
