Hope this tutorial was helpful to you. You learned about how to read the data from and write the data to a serial monitor. We have used the serial monitor in almost all our previous tutorials to print the sensor and actuator data. In next tutorialhere, you will learn about the ultrasonic...

Serial communications are also a handy tool for debugging. You can send debug messages from Arduino to the computer and display them on your computer screen. The Arduino IDE (described in Recipe 1.3) provides a Serial Monitor (shown in Figure 4-1) to display serial data received by Arduino....
进入“Tools”->“Serial Monitor”，将baud rate设置为“115200”，然后按RST按钮检查串口连接。步骤四、 清除 flash 根据生产批次的不同，部分开发板可能内置了预设的B&T固件，固件信息如下图所示：固件位于 OTA 部分。所有新编译的固件将被 OTA 固件自动替换。因此，需要先清除 OTA 固件才能使用已编译的固件。
