I2c i o port expander arduino tutorial

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.

Similar to eBay, sellers on Aliexpress can be either companies or individuals. Aliexpress is different to Amazon because it acts only as an e-commerce platform and doesn’t sell products directly to consumers.

Alexa Controlled LEDs Through Raspberry Pi
Alexa Controlled LEDs Through Raspberry Pi


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.

Syma S107G Remote Control Helicopter with an Arduino
Syma S107G Remote Control Helicopter with an Arduino


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.

Arduino Indoor Garden
Arduino Indoor Garden


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. 

Arduino Apple Watch
Arduino Apple Watch


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.

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.

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!

Relativ - Build Your Own VR Headset for $100


My name is Maxime Coutté. I’m 16 years old and I live in a small village in France where I’m the only teenager. With my best friends, Jonas Ceccon and Gabriel Combe, and my math teacher Jerome Dieudonne (we call him Sensei) we built our own VR headset for $100.
