Analog Input: Use a potentiometer to control the blinking of an LED. Analog Write Mega: Fade 12 LEDs on and off, one by one, using an Arduino Mega board. Calibration: Define a maximum and minimum for expected analog sensor values. Fading: Use an analog output (PWM pin) to fade an LED...
我们先来看个Arduino的实例程序——闪烁的LED,代码如下。 //定义LED所在的引脚#defineLED 13#初始化函数,程序从这里开始,setup函数的内容只执行一次voidsetup(){pinMode(LED,OUTPUT);//设置LED引脚为输出模式digitalWrite(LED,LOW);//设置LED引脚为低电平}//在执行结束setup函数后,循环...
