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.
Arduino is an opensource electronics platform based on easytouse hardware and software. It's intended for anyone making interactive projects.

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.
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).
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.
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.
If you\'ve owned an Alexa or any smart speaker and have Smart Home integration, you\'ve experienced this issue where you have to remember the name of the device to control. I have lots of smart home devices and sometimes remembering names of each one is tricky.
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.
Want to wirelessly control a Mars rover from your laptop?
You are in the right place, this kit does exactly that. 10 minutes is what it takes to wire up the electronics, it doesn\'t even need soldering. For people who know programming, this kit is more than a remote control robot.
Ultrasonic SR04 library for Arduino by Ashish Rajput 2012 CURRENT VERSION. Release 2. 0 24April2012 beta version. HISTORY. Release.
PulseInZero uses interrupt 0 ( pin 2 on arduino uno) PulseInOne uses interrupt 1 ( pin 3 on an arduino uno).
Motion Alarm with PIR and Ultrasonic HCSR04. I use a 220 Ohms resistor connected in between arduino and the piezo attach the switch to arduino interrupt.
Can't use attachInterrupt in a library. But as the interrupt pins are just a few you can write a global variable and.
This time, I will do the same, but using an ATtiny84 and C code no Arduino hardware or libraries. we can use a pinchange interrupt and a timer.
The HCSR04 Ultrasonic Sensor is a very affordable proximitydistance sensor that has been used Temperature sensor and a.
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.
This is my upgraded version of a Digital & Binary Clock using an 8 Digit x 7 Segment LED Display.
I like to give new features for usual devices, specially clocks, and in this case the use of 7 Seg display for Binary Clock is unconventional and it is an interesting and a different way of applying it.
