Getting Started in Kotlin

Kotlin is the official Android programming language and is statically typed. It is fully interoperable with Java, meaning that any Kotlin user can use the Java framework and mix commands from both Kotlin and Java without any limitations. In future tutorial/meetup, we will cover the basics of Kotlin and will look at how to set up the environment. We will also look at its flow structures, such as if { ... } else { ... } expressions and loops. In addition to this,...

Arduino PIR Motion Sensor Tutorial

PIR modules have a 3-pin connection at the side or bottom. The pinout may vary between modules so triple-check the pinout! It's often silkscreened on right next to the connection (at least, ours is!) One pin will be ground, another will be signal and the final one will be power. Power is usually 3-5VDC input. When object comes in detecting area it will return 1 from output pin otherwise it return 0. The IR sensor itself is housed in a hermetically sealed metal can to...

How to read Analog Sensor Data in Arduino Uno Board

Reads an analog input on pin 0, converts it to voltage, and prints the result to the Serial Monitor. Graphical representation is available using Serial Plotter (Tools > Serial Plotter menu). Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground. Potentiometer analogRead() Reads the value from the specified analog pin. Arduino boards contain a multichannel, 10-bit analog to digital converter. This means that it will map input voltages between 0 and the operating voltage(5V...

What is Yii 2.0?

What is Yii 2.0? Yii is a high performance, component-based PHP framework for rapidly developing modern Web applications. The name Yii can be considered as the acronym for Yes It Is!. Yii 2 inherits the main spirit behind Yii for being a simple, fast and highly extensible PHP framework. Whether you are one developer building a fairly simple Web site, or a team of distributed developers building an extremely complex Web application, using Yii is like augmenting your development team with...

Basic Functions of Arduino

Basic Functions of Arduino Configures the specified pin to behave either as an input or an output and other basic operation. pinMode() Description Configures the specified pin to behave either as an input or an output. See the Digital Pins page for details on the functionality of the pins. As of Arduino 1.0.1, it is possible to enable the internal pullup resistors with the mode INPUT_PULLUP. Additionally, the INPUT mode explicitly disables the internal pullups. Syntax pinMode(pin, mode) Parameters pin: the Arduino pin number to set the mode of. mode: INPUT, OUTPUT, or INPUT_PULLUP. See the Digital Pins page...

What is laravel ?

Laravel attempts to take the pain out of development by easing common tasks used in the majority of web projects, such as authentication, routing, sessions, and caching. Laravel aims to make the development process a pleasing one for the developer without sacrificing application functionality. Is laravel a programming language? No, Laravel is a framework, not a language - the language is PHP. If you haven't learned programming itself (not in a programming language, in English), start with Algorithms and Data Structures to learn programming. Is laravel frontend or backend? Is Laravel frontend or backend? The short answer is “backend”....

What is Flutter in short?

Flutter is Cross-platform mobile development framework backed by google it has number of features. Developers are forced to choose between either building the same app multiple times for multiple operating systems, or to accept a lowest common denominator solution that trades native speed and accuracy for portability. With Flutter, we believe we have a solution that gives you the best of both worlds: hardware-accelerated graphics and UI, powered by native ARM code, targeting both popular mobile operating systems. We think of...
