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.

Gammon Forum: Electronics That's why you need to debounce. reset the internal interrupt of the mcp chip and don't just use the arduino interrupt to detect.
Arduino for Ham Radio interrupt. The Arduino Uno has three internal timers, Bounce used to debounce digital inputs.
Protecting IO pins of IO expander in case I would go for an interrupt Consider dumping those tasks under input validation rather than a simple debounce.

NetSensor is an Arduino Kit which allows you to monitor your room from anywhere in the world via Internet.
All you would need is a browser and this kit has all the hardware required to monitor your room and check if its warm, not too humid and if someone has broken into your home.
The devices which connect to internet has been shrinking at very fast pace, Now its got to the size which fits on your fingers and can not only connect to the internet but as also do some sensing.
ESP8266 chipset has made waves since it got introduced, Due to its small size and capablities. This is the first generation of IOT technologies which is going to change the way we live.
It turns out that it is quite easy to get Alexa communicate with Arduino via Raspberry Pi with Node-RED. All you have to do is installing two Node-RED modules and setup up a Node-RED Flow with Alexa Local and Arduino nodes. Here I have a project which has Alexa turn on and off two LED lights as a demo.
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.
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.
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.
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.
Serial communication with Arduino and Processing: we debounce the switch then we read the button status with Serial communication with Arduino and.
