Then, we'll use Python to install proper libraries to read data from Arduino Uno R3. We'll start by installing Raspbian Buster Lite in our Raspberry Pi Zero W. Arduino Uno R3 board or compatible board (you can also consider the Elegoo starter kit).micro SD card (at least 16 GB, at least class 10).Raspberry Pi Zero W (including proper power supply or a smartphone micro USB charger with at least a 3A) or newer board.Steps should also work with newer Raspberry Pi boards. What we needįor this project, I'm going to use a Raspberry Pi Zero W and an Arduino Uno R3. For this purpose, we'll use Pyserial and its terminal tool. ![]() In this guide, I'll show you how to connect your Raspberry Pi to a serial USB port and read its values with Python from the terminal (without a desktop environment). ![]() You can also use Raspberry Pi to dialog with some devices-like Arduino-by using a serial USB port. ![]() Raspberry Pi can be used to interface with the real world from its GPIO, for example, by controlling a stepper motor.
