This article is a thorough explanation on how to read analog input and how to display it in a serial monitor. A practical example is also provided for better understanding.
How to Interface LCD with Arduino in 4-bit and 8-bit Modes
Posted: 2022-02-03 09:40:16 Source: https://linuxhint.com/interface-lcd-4-bit-8-bit-modes-arduino/
There are two modes in which the LCD can be interfaced with Arduino one is the 4-bit mode and the other is 8-bit mode. The major difference between the two is that the 8-bit used the 8 data pins of the display module whereas the 4-bit only used the 4 data pins and only used four data pins. The data transfer rate in 8-bit mode is greater than 4-bit mode. This article explains how to interface LCD with Arduino in 4-bit and 8-bit modes.

How to Interface LCD with Arduino
Posted: 2022-02-03 08:23:11 Source: https://linuxhint.com/interface-lcd-arduino/
In Arduino programming there are multiple ways for displaying the output of the Arduino program or a project. One way of displaying the output is by using a display module or LCD and interfacing it with Arduino. LCD is one of the key components to visually display the output of the data received from various sensors connected with Arduino. This article is a brief guide on how to interface LCD with Arduino.
How to Change HTML Style Through JavaScript
Posted: 2022-02-03 08:15:38 Source: https://linuxhint.com/change-element-content-javascript-3/

Posted: 2022-02-02 23:50:24 Source: https://linuxhint.com/operators-precedence-in-java/
The operator's precedence in Java alike as many of other programming languages. It is carried out by language when an operator is associated with more than one operand. This informative post enlightens the importance of operator's precedence in Java. Moreover, a table containing the precedence order is also provided followed by various examples that implements multiple operators in a single expression.

It's ideal for those with a limited budget but a strong desire to work on the Raspberry Pi 4 and learn Linux. Raspberry Pi 4 is fast enough to help you complete any task that you expect from a desktop PC, and if you are good at programming, Raspberry Pi 4 will provide you with decent programming tools as well. This article explains how a Raspberry Pi 4 can become a replacement for your desktop computer.
How to Use EEPROM library in Arduino
Posted: 2022-02-02 17:00:17 Source: https://linuxhint.com/eeprom-library-arduino/
The acronym EEPROM stands for Electronically Erasable Permanent Read Only Memory. In Arduino programming when a sketch is uploaded to the Arduino board it remains there and is stored in the Arduino until it is erased, or another sketch is uploaded. This data is stored in the EEPROM built in the Arduino. This article is a thorough guide on EEPROM library and its functions in Arduino.
Design and Prototypical Implementation of an IRC Chat Server in Erlang OTP
Posted: 2022-02-02 17:00:00 Source: https://www.linuxjournal.com/content/design-and-prototypical-implementation-irc-chat-server-erlang-otp

Introduction
By the time of this article, digital services provide key functionality to businesses and everyday life. Due to the progress of digitization, the reliance on digital services has been growing rapidly. This process is not only shown by the growing number of inter connected devices that communicate with each other but also by the impact of unavailable services during an incident: On the 4th of October 2021, Meta (former Facebook) and all of its organizations (e.g. Instagram, WhatsApp, Facebook Messenger) were unavailable for up to seven hours. The outage resulted in a huge profit loss for the company and connected businesses. [1]
This outrage shows that modern solutions must be designed resiliently to enable service provisioning during incidents. There are multiple solutions to develop high-available and reliable services that can be applied to various levels in a system’s architecture and design. Some programming languages are specifically designed to meet these challenges. The functional programming language Erlang provides inherent functionality to develop these resilient services.
Therefore, this article presents the exemplary design and development of a communication service based on the Internet Relay Chat (IRC) protocol in Erlang to investigate its availability features.
Background
This chapter deals with the basics of the programming language Erlang. The subchapters give an overview of functional programming and features specific to Erlang.
Functional Programming
Functional programming is a programming paradigm. Various characteristics specify what constitutes functional programming:
-
Pure functions: Pure functions are deterministic functions which always produce the same output value for identical input values. Therefore, it can be concluded that a function cannot be influenced from the outside. Hence, there are no side effects. [2]
-
Immutability: Immutability refers to the fact that data cannot be changed. Once variables have been assigned a value, the variable can no longer be reinitialized. Therefore, reinitialization is only possible by introducing a new variable with the adjusted value. Since classical loops in imperative programming languages require updating variables by e.g. incrementing them, there are no loop statements in functional programming. Iterating over data requires recursive function calls. [2]

Asynchronous Execution in JavaScript
Posted: 2022-02-02 00:10:14 Source: https://linuxhint.com/asynchronous-execution-in-javascript/
Callbacks, Promises, and async/await keywords are the three methods for handling asynchronous execution in JavaScript. Callbacks enable access to the functions when the asynchronous method has completed the execution; Promises assist in chaining the method together, and the async/await keyword provides additional control over the promises. This write-up discussed Asynchronous Execution in JavaScript. Moreover, we also demonstrated the methods of asynchronous execution such as Callbacks, Promises, async/await in JavaScript with examples.
Class Inheritance in JavaScript
Posted: 2022-02-02 00:06:14 Source: https://linuxhint.com/class-inheritance-in-javascript/
You can use the extends keyword for creating a class inheritance in JavaScript and the super keyword to refer to the parent class. With the class inheritance mechanism in JavaScript, the child class can access the methods and properties of the parent class. This write-up discussed class inheritance in JavaScript. We have also explained shadowing methods and inheriting static methods using the class inheritance in JavaScript. Moreover, each of the specified sections is demonstrated with the help of examples.
Binary Search in Java
Posted: 2022-02-02 00:04:13 Source: https://linuxhint.com/binary-search-java/
Binary search algorithm in Java works on an array that is already sorted. Only complete sorting in ascending order is considered in this article. This article begins with illustration of the binary search algorithm. It goes on to explain how to use the binarySearch() methods of the Java Arrays class.
Basic Datatypes in Java
Posted: 2022-02-01 23:53:34 Source: https://linuxhint.com/java-datatypes/
Java data types are categorized into the following types: primitive data types and non-primitive data types. Primitive data types are already specified in the programming language however, non-primitive data types are user-defined. Boolean, byte, char, short, int, long, float, and double fall under the category of primitive data types, whereas string, classes, and arrays are classified in the category of non-primitive data types. We have discussed these data types in detail in this write-up.
