Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to configure our raspberry pi for voice control. We also discussed some methods of reducing vexing noises so that the voice command program understands you. However, in this lesson, we will learn how to tweet from Raspberry pi.
What will we learn?
Assume you wish to add tweeting into a Raspberry Pi software you're developing. This article will show you how to build a Twitter app, get access privilege tokens, and post a tweet. On our Raspberry Pi, we'll make a simple program that tweets the result of the uptime command. This is a made-up example, but it demonstrates what is needed to tweet from a raspberry pi.
For this session, a repo has been set up. Because we'll be referring to code wit ...
to our new beginner’s course on Raspberry Pi. This course is appropriate for anyone using either a traditional Raspberry Pi board or the new Raspberry Pi 400 board that includes an integrated keyboard and display. Learning how to code, building robots, and doing plenty of other strange and exciting things are all possible with this low-cost computer setup. The Raspberry Pi can do everything a computer can do, from surfing the web to viewing movies and music, and playing video games.
Raspberry Pi is much more than a modern computer. It`s created to educate young people on how to program in languages such as Scratch and Python, and it comes with all of the major programming languages pre-installed. The world is in desperate need of programmers now ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us how to use a raspberry pi as a DNS server. We also looked at the benefit of this DNS server. This tutorial will teach us to set up Raspberry pi as a VPN server.
This is an excellent method for increasing your network security and getting access to your local area network from the world wide web, but setting up your VPN server might be a challenge. Pi VPN uses a guided install to turn your Raspberry into a low-cost, high-performance VPN server.
What is Pi VPN?
It is an OpenVPN server optimized for all Raspberry platforms above pi 2. It allows you to access your home network over the internet safely and securely. Smart devices and your network can ...
The IoT is the interconnection of physical objects or devices with sensors and software accessing capabilities to communicate data or information over the internet.
To build an IoT network, we need an interface medium that can fetch, control, and communicate data between sender and receiver electronics devices or servers.
Espressif Systems created the ESP32 Wi-Fi chip series. The ESP32 module is equipped with a 32-bit Tensilica microcontroller, 2.4GHz Wi-Fi connectivity, an antenna, memory, and power management modules, and much more. All of these built-in features of this ESP32 module make it ideal for IoT applications.
Hello readers, I hope you all are doing great. In this tutorial, we will learn another application of ESP32 in the field of IoT (Internet of Things). We are using a PIR s ...
Hello readers, I hope you all are doing great. In this tutorial, we will learn how to update a webpage using Server-Sent Events and the ESP32 web server.
What is Server-Sent Events (SSE)?
It is a server push technology that enables the client devices to receive automatic updates from a server over HTTP (Hypertext Transfer Protocol) connection. SSE also describes how the server can initiate data transmission towards the client once an initial connection with the client has been established.
We have already posted a tutorial on how to implement Web socket protocol with ESP32 which is also a protocol used to notify events to a web client. Both the Server-Sent Events (SSE) and Web-Socket technologies seem to be quite similar but they are not.
The major difference between the two is that SSE ...
Hello geeks, welcome to our new project. Here, we are going to make a very useful project which we can use for ourselves or we can use this as a product as well on an industry level.
In this project, we are going to make a water level indicator. We all know it is one of the most essential products because there are many water tanks in every house or office, and most of them are not easily accessible to check the level of water in it and I think most of us faced the problem such as shortage of water as we do not have anything to monitor the exact amount of water available in the tank and this causes many problems on our daily lives.
Software to install
As we are going to make this project in the simulation first, for that, we will use the Proteus ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to set up a webserver in raspberry pi. We also looked at configuring addclient and deploying apps to our repositories. This tutorial will teach us to set up a free media server on Raspberry Pi.
Using a Raspberry Pi as a multimedia server requires:
An operating system and miniDLNA program installed on your Raspberry Pi,
You can attach various cleanly formatted and fragmented hard disks to your Raspberry Pi for storing and streaming media files.
A basic understanding of how to use a computer, Client-server architecture skills, familiarity with Unix terminal and Secure shell, and a passion for computing and the media are a must!
Even if you ...
Hello readers, I hope you all are doing great. In our previous tutorial, we discussed the implementation of LED interfacing and blinking program with Raspberry Pi Pico using MicroPython programming language. So continuing with our previous tutorial, in this tutorial we will learn how to control the LED brightness using PWM (pulse width modulation technique).
As we mentioned above, in our previous tutorial we implemented the LED blinking program with a Raspberry Pi Pico board. Blinking an LED means turning ON and OFF and thus the process involves only two states that are ‘1’ (HIGH) and ‘0’ (LOW). But, sometimes it is required to change the digital output between these two (ON and OFF states) for example changing the LED brightness. PWM or Pulse Width Modulation technique is used to change ...
Hi Everyone! Glad to have you on board. Thank you for clicking this read. In this post today, I’ll cover Real Life Examples of Workflow Automation.
Workflow automation is a talk of mainstream conversation. Many employees use this process in their organizations but they are not aware of this term. Workflow automation is a process used to automate manual and repetitive time-consuming tasks. It requires a series of tasks that need to be completed in a sequential manner where the process goes from start to finish with a definite goal in mind. For instance, onboarding new clients and approving leave requests are susceptible to errors when done manually. However, with workflow automation software, these tasks are done automatically without human intervention, leaving no room for mistakes or fai ...
Internet of Things is a system of multiple inter-related computing devices. The factor ‘thing’ in IoT is designated to an entity capable of communicating data over a network (IOT), which can be a digital machine, sensor, human being, animals etc. Each component that is included in IoT network is assigned with an unique identity called UID and the ability to communicate data over IoT network without any external human or computer intervention.
Hello readers, I hope you all are doing great. In our previous tutorial, we discussed how to upload data to Firebase Real-time Database using ESP32. In this tutorial, we will learn how to read the data stored on the Firebase Database with ESP32.
We can access the data stored in Firebase database from anywhere in the world, which makes this preferable ...
