Learning rudimentary knowledge gives mind-blowing epiphanies. Don’t you agree? In this tutorial, we are going to dissect the root directory of the Raspberry Pi – a must-know for aspiring Linux professionals. Introduction The Raspberry Pi OS, formerly known as Raspbian, is a Debian-based Linux operating system. It follows the Filesystem Hierarchy Standard (FHS) that the Linux…
A text editor is a software that writes and edits simple text. They are useful for uncomplicated writing and word processing. Some of their applications include programming and writing computer configuration files. You can use two kinds of text editors on a Raspberry Pi: Desktop graphical editors and Command-line editors. Desktop Graphical Editors Desktop graphical…
The Debian-based Raspberry Pi OS is a multi-user operating system. This makes it easier for developers to collaborate with a project. However, it comes with the risk of having unwanted users or malicious software that may corrupt essential data. To combat this, Linux implements file access permissions to control who can read, write, and execute…
Today we are going to discuss the invisible thing that makes computers, including the Raspberry Pi, work. And ultimately, setting up the Pi for actual use. Operating Systems The operating system (also called OS) is an abstraction layer that makes controlling a computer’s underlying hardware easier for users. An abstraction layer is something inside the…
The best thing you can learn about Raspberry Pi is Linux. Not only because it is more powerful than commercial operating systems, but it is also found everywhere, from smartwatches to tablet PCs, cars, enterprise servers to full-blown space satellites, making it a highly desired skill in the tech industry. In this tutorial, you will…
This tutorial is all about the Raspberry Pi – a pocket-sized computer that can teach you several computer science technologies, including writing in several programming languages, building an operating system, and even creating your own gaming console! Raspberry Pi The Raspberry Pi is a low-cost Linux-based computer that is about the size of a credit…
Ever wonder how an .ino file from the Arduino IDE finds its way to an Arduino microcontroller’s flash memory? In this tutorial, we will try to understand the Arduino Sketch build process. Overview The reason why Arduino programming is popular is that it provides layers of abstractions that make it easier for developers to work…
In this tutorial, we are going to design a mobile platform that displays DHT data from an ESP8266 using the Blynk smartphone application. Blynk Blynk is a smartphone application that connects any hardware to the cloud. It lets you design an interactive interface to control and manage a myriad of hardware platforms, including Arduino, ESP266/ESP32,…
Espressif Systems has developed its own wireless protocol for its ESPx series of chips. It boasts a fast wireless connection without needing to connect to a WiFi network. Join me as we both discover what it’s capable of! Introduction The need for fast data transmission stems from the fact that smart devices usually rely on…
If you’re looking for a lightweight IoT communication protocol, and a server that is completely free that supports it, then sit tight! In this tutorial, we are going to create an MQTT broker using Adafruit IO and NodeMCU. Introduction In the previous article Creating an Adafruit IO dashboard using ESP8266, we’ve sent HTTP requests from…
