最后,给UNO控制板插上电池就完成了(如图2.4所示)。 图2.4 完成安装 三、程序代码编写 点击打开“Arduino IDE”编程软件,输入下列代码(如图3.1所示): int buzzer=8; void setup() { pinMode(buzzer,OUTPUT); } void loop() { ...
大多数Arduino板都会自带一个LED灯,不过这个灯可能会根据Arduino板的型号而连接在不同的接口上。就我们所示范的Arduino Uno,来说,它的LED灯是连接到D13接口的。 每个Arduino板都会自带一个常量,LED_BUILTIN,来储存这个接口的数值。 不过,我们也可以在Arduino板上外接一个LED灯,就像下图所示 ...

Arduino Uno有3个定时器:Timer0、Timer1和Timer2。Timer0已经被设置为生成一个毫秒中断来更新millis()报告的毫秒计数器。因为这就是我们要找的,所以我们也会让Timer0为我们生成一个中断! 频率和计数 定时器是一种简单的计数器,它根据16MHz系统时钟的某些频率进行计数。您可以配置时钟除数来更改频率和各种不同的计...
