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).You need to specify the serial port you art using when you create your serial object. To read serial data, you can use the Python serial library. Raspberry Pi Zero W (including proper power supply or a smartphone micro USB charger with at least a 3A) or newer board Open up a text editor or your preferred Python IDE.After this, make sure to restart the Raspberry Pi. The serial login shell is disabled The serial interface is enabled. Once the Raspberry Pi has made the changes, you should see the following text appear on your screen. Steps should also work with newer Raspberry Pi boards. Select Yes when prompted to make use of Serial Port Hardware and press enter. What we needįor this project, I'm going to use a Raspberry Pi Zero W and an Arduino Uno R3. Works exactly as a hardware-based serial port.

The serial port will appear as /dev/ttySOFT0. This module creates a software-based serial port using a configurable pair of GPIO pins. For this purpose, we'll use Pyserial and its terminal tool. Software-based serial port module for Raspberry Pi.
Serial terminal program for raspberry pi how to#
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.
