* Added more serial monitor ideas from [John Lonergan](microsoft#463 … 984e2e4 the design of Serial Monitor is different from Arduino IDE, and we support the same behavor in serial monitor. maybe user don't know how to use serial monitor in extension, here are some steps: ...
Arduino板上有多个模拟引脚（通常标记为A0-A5），可以用来读取模拟信号。In Arduino, analog input usually refers to the voltage value from the sensor, buttons, or other analog device through the analog pins of Arduino. There are multiple simulation pins on the Arduino board (usually marked as A0-A5...
