On most Arduino, the PWM pins are identified with a "~" sign, like ~3, ~5, ~6, ~9, ~10 and ~11. This example code is in the public domain. https://www.arduino.cc/en/Tutorial/BuiltInExamples/Fade */ // int led = 9; // the PWM pin the LED is attached to int brightness...
创建程序后,像之前介绍的那样将其写入Arduino,然后检查LED是否被点亮。 const int LED_PIN = 13 void setup(){ pinMode( LED_PIN, OUTPUT ); } void loop(){ digitalWrite( LED_PIN, HIGH ); } view rawcode01.ino hosted with by GitHub 当对数字输出进行控制时,第4行和第8行的内容非常重要。数字...
