/*Multiple Serial testReceives from the main serial port, sends to the others.Receives fromserial port1, sends to the main serial (Serial 0).This example works only with boards with more than one serial like Arduino Mega, Due, Zero etc.The circuit:- any serial device attached to Serial p...
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(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...
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...
INPUT- - OUTPUT- - RETURN- - 3、Arduino数据类型 3.1 所有数据类型 void void关键字仅用于函数声明。它表示该函数预计不会向调用它的函数返回任何信息。 Boolean 布尔值保存两个值之一,true或false。每个布尔变量占用一个字节的内存。 Char 一种数据类型,占用一个字节的内存,存储一个字符值。字符文字用单引号写...
