arduino Serial Communication Serial Communication with Python
Example
If you have an Arduino connected to a computer or a Raspberry Pi, and want to send data from the Arduino to the PC you can do the following:
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
