外部中断需要外部的触发,在Arduino UNO中数字引脚2和3是连接外部触发电路的,它们的中断号分别是0和1【0表示用引脚2,1表示用引脚3】。在写程序时通常把中断函数写在setup()中
/*** SETUP FUNCTIONS ***/ voidsetup(){ pinMode(ledPin, OUTPUT); pinMode(sensorPin, INPUT); Serial.begin (9600); FastLED.addLeds<WS2812B, ledPin, RGB>(leds, NUM_LEDS); } voidloop (){ val =digitalRead(sensorPin); Serial.println (val); // when...
一开始写Arduino 的时候很不习惯,没有main函数,因为好多东西都被隐藏了。一直想搞清楚,以便编写自己的库文件。于是研究一下午,下面是一些总结。 Arduino工程的初步认识 一、目录规范 当创建一个空的工程,先按下ctrl+s保存一下。这个时候弹出对话框,命名工程。假如命名为LED,并保存在 我自己的Arduino工作目录下 H:...

This is basically an "open collector" and allows multiple output pins to be connected to one Arduino input pin. However, keep in mind that any weak / disturbed signal from one of the receivers will also interfere with a good signal from another receiver....
