模拟信号:Arduino中的模拟信号就是0v~5v的连续的电压值 数字信号:Arduino中的数字信号就是高电平(5V)或者低电平(0V),是两个离散的值 模拟信号->数字信号:ADC(模数转换器) ADC是用于将模拟信号转换为数字信号的电路。将输入的模拟信号通过ADC转换为数字信号,处理器才能对其进行处理。 这里讲的模拟输入是指0~5v...

Arduino控制器通电或复位后,即会开始执行setup() 函数中的程序,该部分只会执行一次。 通常我们会在setup() 函数中完成Arduino的初始化设置,如配置I/O口状态,初始化串口等操作。 1. 2. eg.示例程序 // 给13号引脚连接的设备设置一个别名“led” ; // 在板子启动或者复位重启后, setup部分的程序只会运行一次...
