Serial.println(voltage) 现在,当你打开你在Arduino IDE软件上的串口监视器(可以通过键盘快捷键Ctrl+Shift+M打开),你应该看到一个范围从0.0-5.0的稳定的数据流。随着你转动那个旋钮,这个输入到A0引脚的电压值会随之变化。 /* ReadAnalogVoltage Reads an analog input on pin 0, converts it to voltage, and pr...

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,都会记录下来—小小的进步或是搞不掂的问题,希望能够抛砖引...
