This section of the for-loop is only executed once at the beginning. Test i < 10; Next the loop variable is tested. Here, if it is smaller than 10 then carry on - otherwise the loop is exited. This is executed every time around the loop. ...
Serial.println("Wait for next loop");//延时1 min delay(60000); } 3.3 数据导出并绘制图表分析 连接的SD卡记录到不同传感器的数据后,通过计算机打开SD卡,可以看到名为datalog.txt的文件,这就是数据记录器所采集到的数据环境。分析数据并绘制图表的方法很多,可以采用很多专业的软件完成。本设计只需要做一些简单...
打开“控制面版”,打开“设备与打印机”,点击“添加设备”: 如果出现HC-06,说明蓝牙模块被激活,可以进行连接。点击Next,输入密HC-06的默认密码1234: 点击Next后,HC-06将与Windows配对。此时HC-06作为计算机的从属设备,就可以与之进行无线通信了。接下来确定这个设备映射到计算机上的串口的编号。在“设备与打印机”...
