与 Python 的串行通信

如果你将 Arduino 连接到计算机或 Raspberry Pi，并且想要将数据从 Arduino 发送到 PC，你可以执行以下操作：

Arduino

void setup() {
  // Opens serial port, sets data rate to 9600 bps:
  Serial.begin(9600);
}

void loop() {
  // Sends a line over serial:
  Serial.println("Hello, Python!");
  delay(1000);
}

Python：

import serial

ser = serial.Serial('/dev/ttyACM0', 9600)  # Start serial communication
while True:
    data = ser.readline()  # Wait for line from Arduino and read it
    print("Received: '{}'".format(data))  # Print the line to the console
