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.

The ADRF6510 is a matched pair of fully differential low noise and low distortion programmable filters 6pole filter 1 MHz to 30 MHz in 1 Low Pass and.
Lowpass filter. From In these cases you often want to calculate a filtered output float alpha, char useprevious) pin: arduino analog pin.
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.
First of all, you need a suitable IoT gateway with a couple of free GB hard disk space (libraries can be heavy sometimes). Follow the Getting Started section of Create to get your Gateway up and running (choose Ubuntu distribution, for example).
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.
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.
I made this LED pendant light from plywood, LED strips, and flexible LED channel. Since I designed this for my living room, the music syncing had to be incognito. With this in mind, I used warm white / cool white / amber LED strips, instead of RGB strips.
These days almost everybody is connected to the internet on their phones, The thing people like doing most is staying in touch with friends on Instant Messengers like Whatsapp, Facebook, Hangouts, Telegram.
Sonar has always been a fascinating subject, the green dash board and flickering dots representing enemy planes and submarines has never stopped fascinating the hobbyist.

Learn how to use a Lidar sensor and an Arduino to build a configurable forward-facing obstacle detection solution for your 3DR Solo.
Here it comes: an affordable, front facing collision detection solution for your 3DR Solo Drone!
This hack describes everything you need to establish Lidar-based obstacle detection with direct feedback in the Solex App.
Arduino boards are great for experimentation. You just plug the wires in, and the connections stay there with spring force. On the other hand, they also pull out quite easily, so I developed an Arduino Uno enclosure that when the lid is tightened, it also tightens down the wires going into the board, locking them down and providing a good amount of strain relief.
