A standard Arduino has a single hardware serial port, but serial communication is also possible using software libraries to emulate additional ports (communication channels) to provide connectivity to more than one device. Software serial requires a lot of help from the Arduino controller to send and...
Your sketch must call the Serial.begin() function before it can use serial input or output. The function takes a single parameter: the desired communication speed. You must use the same speed for the sending side and the receiving side, or you will see gobbledygook (or nothing at all) on...
// if using Processing 2.1 or later, use Serial.printArray() println(Serial.list()); // Uses the first port in this list (number 0). Change this to // select the port corresponding to your Arduino board. The last // parameter (e.g. 9600) is the speed of the communication. It /...
More specifically, when you use Serial with Arduino and Raspberry Pi, you’re using the UART protocol. UART means “Universal Asynchronous Reception and Transmission”. Basically it’s anasynchronous multi-master protocolbased on the Serial communication, which will allow you to communicate between th...
Serial.write(thirdSensor); }} 2、串口调用和应答(握手) - Serial Call and Response (handshaking) Send multiple variables using a call-and-response (handshaking) method. 使用调用和应答(握手)方式发送多个变量。 This example demonstrates multi-byte communication from the Arduino board to the computer ...

exiting. I'm thinking the problem here is that your arduino environment is trying to communicate to the device over the same serial port that your PHP is trying to talk over too. You'll probably have to investigate how to disable that communication while youre trying to use your PHP script...
