Arduino is an open source computer hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices and interactive objects that can sense and control objects in the physical world. The project's products are distributed as open-source hardware and software, which are licensed under the GNU Lesser General Public License (LGPL) or the GNU General Public License (GPL), permitting the manufacture of Arduino boards and software distribution by anyone. Arduino boards are available commercially in preassembled form, or as do-it-yourself (DIY) kits.
Swift Tutorial: How to Use an Array in Swift See the post The Swift Swift Tutorial: Very often we may set an array to be optional to check for an empty state.
Variables. A variable is a place to store a piece of data. It has a name, a value, not variable names, and you can assign values of any type to a variable.

Gardening in the modern age means making things more complicated and arduous, with electrons, bits, and bytes. Combining microcontrollers and gardening is a really popular idea. I think that’s because gardens have very simple inputs and outputs that are easy to wrap your head around.
Connecting to the internet has not been easier, With the advent of the new IOT ( Internet of things) module ESP8266 its a breeze to connect your microcontroller and Arduino projects to the internet.
Disassemble an old printer (in this case a dot matrix) and drive the stepper motor(s) for linear motion or rotation. With Arduino.
I need some linear motion for a new project and I decided to disassemble an old dot matrix printer in order to reuse its stepper(s), by controlling them via a A4988 driver.
My staircase has claimed a broken toe some time ago. Fortunately, it wasn’t my toe, but I feel for the poor fella. The toe is OK now, but it got me thinking, is there anything I could do to reduce the risk of dealing with another victim? Plus if I could do this on the cheap, that would be super!
This project is about controlling Christmas lights, a 5 Watt CFL, and a fan through Arduino/Genuino 101 consisting of Intel Curie module using Bluetooth Low Energy through a Android Smartphone. The components which are used in developing this project for e.g. a 5 V 4 channel Relay, male-female pins are cheap and are easily available at any hardware shop.
This is our original weather station kit. You will be surprised how much you can learn from it, such as how to connect sensors and write program to read the data, and display it on a LCD display. What you can do with this kit is only limited by your imagination.
Amazon Echo is fun to use and it has a really cool feature to control most of the home automation devices that are available out there, like Philips Hue and other devices. But nothing is better than experimenting and building your own DIY Home automation system.
the global variable G is initialized with this same value. If the object is not a string you may not need to call this function.

C Notes: Dynamic Allocation of Arrays Using a small size may be more efficient for the typical To create a variable that will point to a dynamically.
Some time ago I saw people reverse engineering the infrared protocol of the Syma S107G toy helicopter and I wanted to get my hands on it as well. It is a coaxial helicopter, which means that it doesn\'t require a torque cancelling tail rotor. Yaw is controlled by using the speed difference to a second rotor underneath the main rotor, which spins in the opposite direction.
Control any of the 55 RGB LEDs on the tree, let Santa twerk for you, control a model railroad, or display custom text on an LED dot matrix.
Have you always wanted anyone in the world to be able to control your X-mas decoration in your living room? - No? - We neither, but we built it anyway.
