arduino的serial.write()和serial.print()的区别在于它们在底层实现和面向对象设计上的运用。从基本层面看，serial.write()用于输出单个字节，而serial.print()则用于输出字符串或整数。这种区别源于面向对象设计中抽象编程与具体编程的层次划分。在arduino的实现中，底层寄存器操作由具体的派生类，如Serial，...
As a result, your sketch will begin sending data to the USB serial port faster than you can open the serial port. This means that if you have any serial output commands (Serial.print or Serial.println) in your setup() function, you won’t see it in the Serial Monitor because you can...
