In this Arduino Serial example, we will write text to the Arduino serial port, which will send it over the USB cable to your computer, which will then display that text in a terminal window. In the ‘setup()’ function mentioned above, add the following lines to start the Arduino serial...
Serial.println(sensorValue, DEC); 现在,当你打开Arduino IDE的串口监视器,你会看见“0”的数据流(如果开关打开)或者“1”的数据流(如果开关闭合) 当开关为高电平时,pin13的LED灯会变亮;开关为低电平时,LED灯熄灭 /* Input Pullup Serial This example demonstrates the use of pinMode(INPUT_PULLUP). It...
