How do you send serial data in Python?
Transmitting Data:
Firstly, we need to include the serial library. We can then declare an instance of the serial port and add the SerialPort, baudRate and timeOut parameters , I’m using serial0, 115200 and 0.050. To find your Pi serial port use the command ‘lsdev’. In my case, my serial port was serial0.

Python provides an easy way to do cross platform serial communication using pySerial module. The modules hides all the OS specific peculiarities and presents a uniform simple interface for programming the serial port. The code written with pySerial can run unmodified on Windows and Linux systems.
What are serial ports for?
A socket that connects to a serial interface (one bit following another over one line). Serial ports are widely used by sensors for data acquisition, and they were standard on early computers for connecting a modem, mouse and other peripherals. Old Macs used the serial port for printers.
Can Arduino talk to Python?
To communicate with the Arduino using Python, we need to install the PySerial package. You can install the PySerial package at the Anaconda Prompt using the command conda install pyserial . Note the (arduino) virtual environment should be active when you run the conda install command.
