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.

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.
We use infrared transmitters when making Cubecon. So we studied how to send infrared values to an infrared transmitter. We also studied an infrared receiver to make sure it works properly.
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.
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.
If you\'re like me, then you have a small pile of clothes on the floor that may or may not be dirty. This could include jeans, dress shirts, and barely worn shorts. So how can you tell which clothes are clean or dirty? I came up with a way to track various articles of clothing using NFC and a Raspberry Pi.
I wanted a smartwatch that showed me notifications from an iPhone, was small enough to wear, and had a rechargeable battery that lasted for at least a day. I created my own Apple watch based on an Arduino. It is a smartwatch based on an Arduino mini pro, which is connected to the iPhone over Bluetooth.
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.
I'm looking to put together a simple mains frequency monitor based on the Arduino platform. The mains here are 250 V @ 50 Hz, but obviously these fluctuate slightly.
