Analog input, analog output, serial output Reads an analog input pin, maps the result to a range from 0 to 255 and uses the result to set the pulsewidth modulation (PWM) of an output pin. Also prints the results to the serial monitor. The circuit: * potentiometer connected to analog pi...

Serial.println("Please input on or off. :)"); command=""; } } } 不算太复杂。很简单的一个程序 打开串口程序: 继电器上就开关,开关程序了。 上面有用到的一些单片机的基础知识。至少要知道单片机的基本原理。 还好以前学过51单片机。所以还懂得一些。上面的代码是自己写出来的。
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...
