In the program below, the very first thing that you do will in the setup function is to begin serial communications, at 9600 bits of data per second, between your board and your computer with the line: 在下面的程序中,
Serial.begin(115200);...and in the IDE you leave it at the default of 9600.For the Arduino it sends data at a period of 8.6us (1/115200). If there are 10 bits transmitted then its complete in 86us. The ide will not even see the bits as its receive period is 104us. Well, it...
begin(9600); // send and receive at 9600 baud } int number = 0; void loop() { Serial.print("The number is "); Serial.println(number); // print the number delay(500); // delay half second between numbers number++; // to the next number } Connect Arduino to your computer just ...
In the following program below, we commence with serial communication within the setup function at the rate of 9600 bits of data per second, this is initiated between the Arduino board and the attached computer:Serial.begin(9600); In the next step we trigger digital pin 2, the pin that wou...
begin(9600); } void loop() { int incomingByte; if (Serial.available() > 0) { incomingByte = Serial.read(); Serial.print("USB received: "); Serial.println(incomingByte, DEC); HWSERIAL.print("USB received:"); HWSERIAL.println(incomingByte, DEC); } if (HWSERIAL.available() > 0)...

Of course - any URL could be opened using Kernal or BASIC I/O commands likeOPEN,CLOSE,PRINT#,GET#orINPUT#, meaning you don't need a modem or a network card with dedicated application anymore! Just open a byte stream via a TCP socket: ...
Color coating is not imperative, but helpful if you have enough wires. In the case you were foolish in your design and have an abundance of wires, it is helpful to begin connecting your ground/power connections between components (as shown in step 4). You should only do this if necessary...
Select the proper serial port and board, and upload the example to your Arduino. Once uploading has finished, the library demo should begin. It will run through examples of using almost every function in the library. All that's left is to sit back and enjoy the show!
