Note that you don't have to use the digital pin numbers to refer to the pins. You can also use some predefined macros that maps "Arduino pins" to the port and port number: //Use PIN_PB5 macro to refer to pin PB5 (Arduino pin 13)digitalWrite(PIN_PB5, HIGH);//Results in the ex...

37款传感器与执行器的提法,在网络上广泛流传,其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块,依照实践出真知(一定要动手做)的理念,以学习和交流为目的,这里准备逐一动手尝试系列实验,不管成功(程序走通)与否,都
Standard Arduino boards (Uno, Duemilanove, and Mega) have a green LED power indicator located near the reset switch. An orange LED near the center of the board (labeled “Pin 13 LED” in Figure 1-4) should flash on and off when the board is powered up (boards come from the factory ...
