如果您输入“1”,您将切换到继电器1,如果它是“OFF”为“ON”,如果是“ON”则为“OFF”。发送“2”则会对继电器2进行相同的操作。对于这两个继电器,状态保存在布尔型变量(“relay1State”和“relay2State”)中,并且对于每个继电器,LED会在其真正为“ON”时亮起。 除了Arduino之外,不需要任何其他东西来使用该...

value:0到255之间的PWM频率值, 0对应off, 255对应on。 返回值 无 想想,如何通过两个按键开关实现亮度调节呢?当按第一个按键开关时,亮度值增加,按一次开关,亮度值增加一固定数值,同理,第二个开关也是按一下,亮度值减小一固定数值,最后将按键开关的操作产生的结果通过analogWrite()函数的模拟信号输出给LED。
