![]() ![]() ![]() The final folder "tree", will look like: /rpiWebServer Go to your newer created folder: cd rpiWebServerĪnd create the 2 new sub-folders: mkdir static Now, 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): ![]() The above command will create a folder named "rpiWebServer". 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. The above block diagram shows what we want to accomplish and the video below can give a hint about it: 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. a Web Jorney With Flask and SQLiteįlask is called a micro framework because it does not require particular tools or libraries. After you read this tutorial, please give a visit to its continuation: From Data to Graph. With Flask, will be very simple to control Raspberry GPIOs over the internet. For this project, 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. If you like it, please give your vote by clicking at the above banner. You can quickly check from the terminal if your Raspbian successfully updated to Buster.This Instructable is competing on contests: " Remote Control" and " Raspberry Pi". Reboot the device when the upgrade completes: sudo reboot Check Raspbian Version to Confirm Raspberry Pi Update Use the space bar to scroll if the installation shows a page of information and press q to resume the upgrade. Then, run this command to complete the upgrade: sudo apt dist-upgrade When you finish, update your package list: sudo apt update We will use vi: sudo vi /etc/apt/sources.listĭo the same for the raspi.list file: sudo vi /etc/apt//raspi.list Locate the sources.list file in the /etc/apt/ directory and replace every instance of the word stretch with the word buster. To update Raspbian from an older version (for example, Stretch) to the latest (Buster, at the time of writing), you need to edit a few files. To reboot your device, enter: sudo reboot Update Raspberry Pi to Buster from an Older Version of Raspbian If you want to free up some space on your Raspberry Pi, run the clean command to remove the downloaded.
