In this Python and Arduino tutorial, we explain how to properly develop a serial communication interface between a computer running a Python script and an Arduino microcontroller. In particular, we explain how to send and receive back number and string messages between a computer running a Python script and an Arduino program. This tutorial is developed for a Windows operating system. In our next tutorial, we will explain how to establish the communication interface in a Linux Ubuntu operating system.

The material and concepts that we explain in this tutorial are extremely important for robotics, mechatronics, and control engineering students and professionals. For example, you can use the ideas explained in this tutorial to develop your own serial communication interface between a PC computer or a Raspberry Pi running ROS2 and Arduino boards. In this way, you can use Arduino as a lowlevel microcontroller that will control motors and read sensor information and that will be integrated in the ROS2 environment.
