In the previous tutorials, we discussed sequences and unordered collections in Python. We also learned about operations, functions, and methods applicable to them. There can also be more complex data structures in an application. The data values in these data structures can have a complex relationship and behavior. These data structures are defined as user-defined…

In the previous tutorial, we discussed manipulating data values in lists and byte arrays. Python also has mutable unordered collections like sets and dictionaries. Let us see how data values/objects in sets and dictionaries can be manipulated. Sets Sets are unordered mutable collections of items. The items in a set can be any arbitrary immutable…

In the previous tutorial, we discussed basic syntax and elements of Python language. In Python, there are six types of sequences – strings, bytes, byte arrays, range, tuples, and lists. The strings, bytes, range, and tuples are immutable sequences and cannot be modified once defined. It is only possible to create or destroy these sequences.…

In the previous tutorial, we discussed the syntax of Python — identifiers, keywords, comments, statements, literals, and some data types in Python. We also discussed that Python is object-oriented in that everything in Python is an object, and even data types are classes. Python objects can be mutable or immutable. Python objects that point to…

In the previous tutorial, we discussed the Python language, its applications, implementations (CPython, Jython, IronPython, and PyPy), and IDEs. We also discussed writing Python scripts and modules and learned to run Python scripts through IDLE and Bash shell. Before we jump to controlling hardware via Python scripts, it will be useful to have a strong…

In the previous tutorial, we successfully set up a Raspberry Pi Linux desktop. Let us now start learning Python. We could have jumped right to controlling hardware using Python scripts, but this will defeat the very purpose of using Raspberry Pi and a Very-High-Level-Language (VHLL) like Python to control electronics. We can easily control electronics…

In the previous article, we discussed the role of an operating system. We explored about Linux as a popular open-source operating system that can be used and modified to be used for desktop, mobile, server, cloud, mainframe, supercomputer, cluster, and embedded computing. Raspbian, the official OS for the Raspberry Pi itself is based on Debian…

In the previous article, we discussed various Raspberry Pi models. We also discussed situations in which particular models deem suitable. Most of the time, you will be using RPi as a Linux computer. Raspbian, the official operating system for Raspberry Pi itself is a variant of Debian OS (a Linux Distribution). There are other operating…

In the previous tutorial, we discussed what Raspberry Pi is, operating systems we can run on it, programming languages that can be used with it, the advantages and limitations of Raspberry Pi, and what Raspberry Pi can be used for. We also learned about other single board computers comparable to the RPi. The following models…

Raspberry Pi is a credit-card-sized single-board computer developed by Raspberry Pi Foundation. It was developed as a low-cost microcomputer to impart computer skills to school children. It comes without any power supply or peripherals, and it is supposed to be programmed in Python —  the reason for the ‘Pi’ in its name. Raspberry Pi (RPi)…

We will make a straightforward web application with a frame that permit a client to send a message to the Raspberry Pi utilizing Flask in a web browser. This will permit us to control the Raspberry Pi from a PC, tablet or smart phone. At the point when the form is submitted, it will send the message to the LCD by means of the Raspberry Pi’s GPIO ports. All the code, including the web application, is in Python and HTML.

The Wiring Pi project is used here to switch the GPIO pins high and low. Run the following commands for downloading Wiring Pi and install.

In this project the Raspberrypi board is booted with the Ubuntu OS and is connected to the Ethernet port of a Windows7 PC. The board is connected to the internet connection as explained in the project Connecting the Raspberrypi to the internet. The IP address of the Raspberrypi board has been obtained to remote login in the TUI using the PUTTY and is remotely accessed using VNC.In this tutorial we use a Python web framework called Flask to create a dynamic web server in Raspberry Pi. While there’s a lot you can do with Flask “out of the box,” it also supports many different extensions for doing different operations such as user authentication, generating forms, and using databases.

In this project, our ultimate goal is to find and solve the different requirements in making a web controlled robot that recognizes and converts textual messages placed in real world to the computer readable text files. Our objective is to integrate the appropriate techniques to explain and prove that such capability, using their limited hardware and software capabilities and not to develop new character recognition algorithms or hardware for doing that.

In this project a Raspberry Pi board is booted with Ubuntu OS and is connected to the Ethernet port of a Windows7 PC. The board is connected to the internet as explained in the project how to connect the Raspberry Pi to the internet. The IP address of the Raspberrypi board has been obtained to remote login in the TUI using PUTTY and is remotely accessed using VNC.

Now voice control is not only limited to high end devices such as smart phones or iPhones. The Raspberry Pi, which is an open source hardware and completely customizable offers you the same. Plus, it’s cheap! You can customize it to play music, open gmail or maybe tell you some jokes.Here is a simple yet interesting example on how to customize your Raspberry Pi to light a led using voice control. In this tutorial we will learn how to install Voice Command, and making the configuration to turn a Led on and off.

This article is to make the process of transferring files from a Windows PC to Raspberry Pi easier. The Raspberry Pi is connected to a Windows PC through Ethernet cable and the GUI is obtained using a VNC server. Sharing files between Raspberry Pi and Windows is often very useful for Raspberry Pi users. Whether we need to transfer media files to the Raspberry Pi or want to share some software packages. This article discusses how to enable file sharing for a folder on the Raspberry Pi running the Raspbian OS.Microsoft developed the protocol called Common Internet File System (CIFS) for transfer of files between windows machines. The most popular implementation of CIFS in LINUX system is known as Samba and it allows Raspberry Pi to act as a CIFS file server, which allows a Windows PC to mount a folder on a Raspberry Pi and then allowing to modify(copy, delete, read and write) the files on it.

This article is to provide step by step instructions for making Raspberry Pi as a webcam server where we can live stream video over a local network using python scripts and some required packages. A software package used in this tutorial is Motion which is an open source software with a number of configuration options which can be changed according to our needs. Here configurations are to be made so that it allows you to create a remote webcam for your Raspberry Pi so that you can view it from any computer on the local network.

This article is to provide step by step instructions for making Raspberry Pi as a web server where we can publish our web pages over local network. Apache is a prevalent web server application you can introduce on the Raspberry Pi to permit it to serve pages. All alone, Apache can serve HTML documents over HTTP, and with extra modules can serve element website pages utilizing scripting tools, for example, PHP. The fundamental services which are required to turn your Raspberry Pi into a web server are, Apache (the web server itself), PHP (scripting language).

This article is to provide step by step instructions to run a Python code in the boot of Raspberry Pi automatically. Sometimes we may want to run a Python script when Raspberry Pi boots up, like Webserver applications need an auto start of the server so that remote access is possible. There are a number of different techniques to do this, one of those is crontab. A crontab is a job scheduler that allows the system to perform tasks at defined time or intervals. It is a very powerful tool and useful in lots of situations. You can use it to run commands in the boot or a python script in this case.
