Arduino codevoid setup() { Serial.begin(9600); } void loop() { if (Serial.available() > 0) { String data = Serial.readStringUntil('\n'); Serial.print("You sent me: "); Serial.println(data); } }Here we check if the Arduino has received data with Serial.available(). This will...

可以使用 Arduino 软件串口监视器来查看发送数据,或者其他可以读取串口数据的程序,如:Processing(参考下面代码)Flash、PD、Max/MSP(参考下面的示例)等。下面的示例将接收到的字符串使用逗号切分,并将之重新转换为数字。 Compare this to the Serial call and response example. They are similar, in that both use ...
4.3. Receiving Serial Data in Arduino Problem You want to receive data on Arduino from a computer or another serial device; for example, to have Arduino react to commands or data sent from your computer. Solution It’s easy to receive 8-bit values (chars and bytes), because the Serial fu...
Basic Examplelet serial; function setup() { // Instantiate our SerialPort object serial = new p5.SerialPort(); // Let's list the ports available let portlist = serial.list(); // Assuming our Arduino is connected, let's open the connection to it // Change this to the name of your...
