打开Serial Monitor(串行监视器)。监视器应该不断显示消息,指示X、Y和Z轴的加速度。三个轴在加速度计上用小图表示。 图7 加速度计模块以及三个轴向 要测试加速度计,请在其中一个轴向上突然移动该模块。这时,该方向上的加速度分量会发生变化。 输出示例如下: ...

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...
