arduino – How do I send single character ASCII data to a serial port with python – Education Career Blog

I’v looked at pyserial but I can’t seem to figure out how to do it. I only need to send one at a time? Please help?

Using pySerial:

Python 2.x:

import serial
byte = 42
out = serial.Serial("/dev/ttyS0")  # "COM1" on Windows
out.write(chr(byte))

Python 3.x:

import serial
byte = 42
out = serial.Serial("/dev/ttyS0")  # "COM1" on Windows
out.write(bytes(byte))
