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),[1] 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.

It is a type of lamp which consist of magnetic reed switch, integrated with relayand Arduino board. This small magnet which is hidden under my hand which will activate the relay and the lamp. This is the secret behind the lamp.
This project can be useful for you if you have a website that you can use to keep the data. The common way is to set the ESP8266 to server mode and connect to it from the internet by entering your router IP address in a browser. My internet provider don\'t let me do that by changing my IP address each time I enter the IP address.
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.
We are engineers and also hobbyists who passionately involve in embedded system and software projects. These development boards are the best value kits to start your first microcontroller projects.
Neopixels or WS2812 what the real name is are amazing LEDS nothing is impossible, and i will proof that this year on this platform for YOU.
I built myself a voice controlled home theatre, with background light, screen and projector control. With an ESP8266 and an Arduino Nano. I\'ve got my girlfriend an Amazon Echo device for Christmas. Some days later I thought that this device on its own, is a little boring. So I promised her to make us a voice controlled smart living room... and this is my way to it.
You may have seen these fun, fluffy clouds hanging in someone\'s house or office as light fixtures. We\'re going to adapt the design to be a wearable. Yup, a giant, fluffy, cloud shaped wearable. Also, it won\'t be cloud connected, but it will use a button to change patterns, which for our purposes actually works better.

Android is a great platform to start building your apps, but its not the simplest to start with. For that reason we at hobbyist have built a kit which will take you through the process of building an App step by step.
In my heart I know we are stuck with the QWERTY keyboard but that doesn’t stop me wanting something different. I have thought about switching to Dvorak or Colemak key assignments but don’t want to deal with the problem of mental interference when I have to switch back to a normal keyboard.
