The Adafruit.io
Adafruit.io is a cloud-based IoT platform that enables real-time data visualization and device control through web dashboards. It provides free service with an intuitive interface for connecting IoT devices via WiFi, using authentication keys and feeds to manage data flow between devices and dashboards. In this article, we demonstrate how to connect an ESP32 microcontroller with a BMP180 sensor to an Adafruit.io dashboard for monitoring environmental data and controlling an LED remotely. Required Components ESP32 development board BMP180 sensor (temperature, pressure, altitude) Blue LED Breadboard and jumper wires Adafruit.io account Circuit Connections Connect ...
Read MoreThe First IOT Program
To start learning IoT, first, it is important to learn how to make circuits using a breadboard and a microcontroller. Then it is important to control that circuit using a program. There are some simulators available to make the beginner of IoT learn both these concepts without even having the IoT devices available. However, to get real results, using the circuit components and making the actual circuit is important. In this article, using two different examples, the way to start IoT programming is given. In example 1, the Wokwi simulator is used and in example 2, the actual circuit using ...
Read MoreJava program to read a large text file line by line
This article includes the way to read text files line by line in Java. Here, the three different methods are explained with examples. Storing a file in text format is important especially when data from one structured /unstructured form is transferred to another form. Therefore, basic file transfer systems integrate the txt file reading and writing process as their application components. Therefore, how to use text file reading and writing methods is also important for making the parsers. Multiple Approaches The given problem statement is solved in three different approaches − By using the BufferedReader ...
Read MoreJava Program to Print the Months in Different Formats
In this article, we are going to use various approaches for formatting the months using different libraries of Java programming language. There are several ways to display months. Sometimes the months are written as numbers, sometimes the months are written in long form or they are written in short forms. Using java.time.Month In this approach, the months are printed by specifying the month number that starts from the number 1. For instance -> Month.of(1) will give JANUARY. Example In this Java program, we are printing all 12 months name. import java.time.Month; public class ShowMonth { ...
Read MoreJava program to print Swastika by taking input from user
Swastika is a religious symbol of Hinduism, Buddhism, and Jainism. In this article, we will learn to print Swastika by taking user input. Here, are three different approaches for making this design using Java. In all the approaches, the size of the Swastika is decided by the user. The user provides the input for the table or frame size. The Swastika is often used as an example to learn rows, columns, and tabular layout concepts using different languages including Java. Making Swastika using Java. Here, three different approaches are used to make this design using Java − ...
Read MoreJava Program to open the Command Prompt and Insert commands
This article uses various approaches for selecting the commands inserted in the opened command window through the Java code. The command window is opened by using ‘cmd’. Here, the methods of doing the same are specified using Java code. The Command window is first opened using the Java program. It is opened as a child process. If the java program is run in an existing cmd window, another one is opened as a new process. Further, different types of commands are inserted and executed in that opened command window via the java code. These programs may not work in ...
Read MoreUsing The Audio in Snack
Audio is a common component of mobile apps. Audio can be used in apps in many ways. Audio can be selected from the mobile, it can be used from any online link, or can be included in the project itself as local audio. Expo-av can be used in all these cases for integrating sound into mobile apps. In this article, the React native and javascript code is shown with three different examples where in the first example, an audio file is browsed from the device. In the second example, the audio is taken from an online link and mixed with ...
Read MoreUsing Cards in Snack
Sometimes, the task is to show a small bounded area with some text, picture, or colors and to retrieve more information from it later or to perform some actions on selecting that item. For this Card from react-native-paper can be used. More than one Card can also be used on a Screen, integrating it as a list item and it can be made clickable. In this article, the React native and javascript code is shown with two different examples where first a single card with an Image is used in an app, and in the second example multiple cards are ...
Read MoreUsing Tabs in Snack
Tabs are created to implement multipage views in apps. Tabs are often placed on the top or at the bottom of the screen. Some libraries permit making tabs in mobile apps. Tabs can also be made using simple components like buttons. In this article, the React native and javascript code is shown with two different examples where in the first example, the buttons are used to make tabs. In the other example, the createMaterialTopTabNavigator from '@react-navigation/material-top-tabs' is used to make tabs and then render these on the screen of the device. Algorithm 1 Step 1 − Import Text, View, StyleSheet, ...
Read MoreText to Speech Examples in Snack
Text to Speech is an important area where the written language text is converted into speech form. For using Text to Speech conversion, functionality from expo-speech can be used. In this article, the React native and javascript code is shown with two different examples, where in the first example while showing the text-to-speech conversion, the pitch and speed change are shown along with the original conversion. In the second example, the pause, resume, and stop methods are demonstrated and the user can also enter the text at the time of conversion. Algorithm-1 Step 1 − Import Text, View, StyleSheet, and ...
