Can be Geany, “nano” at Terminal or the RPi Text Editor (LeafPad) that is located under “Accessories” Main Menu. You can use any Text editor to create your HTML file. So, we will create a file named index.html, that will be saved on /templates. This is, in fact, important, otherwise, you would complicate the Python Script putting all on it.Ĭreating an HTML file that will be located in the “template” sub-folder, we can use separate files with placeholders for spots where you want dynamic data to be inserted. Let’s sophisticated our “Hello World” application, creating an HTML template and a CSS file for styling our page. The application will be running unless you type +. On the first picture above you can see what will appear on your terminal. Now, run the above application program: sudo python3 helloWorld.py In my case: 10.0.1.27 Running the Application If you are not sure about your RPi IP address, run on your terminal: ifconfigĪt wlan0: section you will find it. Once this script is running from the command line at the terminal, the server starts to “listen” on port 80, reporting any errors: if _name_ = '_main_': app.run(debug=True, port=80, host='0.0.0.0') Raspberry PI IP Address: In this case, only send the text “Hello World!” to the client’s web browser thru “return” def index(): return "Hello Word"Ĥ.

Run the index() function when someone accesses the root URL (‘/’) of the server. Create a Flask object called app: app = Flask(_name_)ģ. Load the Flask module into your Python script: from flask import FlaskĢ.

Now, let’s create our first python WebServer with Flask: The final folder “tree”, will look like: /rpiWebServer /static /templates The Python WebServer Application Go to your newer created folder: cd rpiWebServerĪnd create the 2 new sub-folders: mkdir static On this folder, let’s create 2 other sub-folders: static for CSS and eventually JavaScript files and templates for HTML files (or more precisely, Jinja2 templates. There we will save our python files (application): /home/pi/Documents/Server The above command will create a folder named “Server”. The best when you start a new project is to create a folder where to have your files organized.

Go to Terminal and enter: sudo apt-get install python3-flask The first thing to do is to install Flask on your Raspberry Pi. On this tutorial, we will use a Raspberry Pi as a local Web Server, where we will control via a simple webpage, 3 of its GPIOs programmed as outputs (acting as actuators) and monitor 2 of its GPIOs, programmed as inputs ( sensors). However, Flask supports extensions that can add application features as if they were implemented in Flask itself. It has no database abstraction layer, form validation, or any other components where pre-existing third-party libraries provide common functions. Introductionįlask is called a micro framework because it does not require particular tools or libraries. With Flask, will be very simple to control Raspberry GPIOs over the internet.Īfter you read this tutorial, please give a visit to its continuation: From Data to Graph: a Web Jorney With Flask and SQLite 1.

For this project here, we will use FLASK, a very simple and free microframework for Python.

For example, on my tutorial: IoT - Controlling a Raspberry Pi Robot Over Internet With HTML and Shell Scripts Only, we have explored how to control a robot over the local network using the LIGHTTPD WebServer. Let’s create a simple WebServer to control things in your home. Then, we'll use Python to install proper libraries to read data from Arduino Uno R3.Python WebServer With Flask and Raspberry Pi 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.
