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, [...]


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 [...]

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 [...]
