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.
I2C is a 2wire serial When the MPR121 senses a change, it pulls an interrupt pin helpful in getting your MPR121 up and running with your Arduino.
Video embeddedIt is a 2line serial communication bus: Arduino interrupt: The MPR121 sensor has an IRQ.

LIDAR (Light Detection and Ranging) is an optical remote sensing system which can measure the distance of a target by illuminating it with light. LIDAR technology is being used in Robotics for the perception of the environment as well as object classification.
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.
Yes, you read the title correct. Have you ever forgot your birthday, that you need someone else to remind you about it ? Or what if you can gift to someone you love, a device that\'ll wish them on their birthday for 50 times ?
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.
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.
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.
Android is a great platform to start building your apps, but its not the simplest to start with. For that reason we at hobbyist have built a kit which will take you through the process of building an App step by step.
MIDI is a serial protocol that operates at 31, 250 bits per second. MultiSerialMega Use two of the serial ports available on the Arduino and Genuino Mega.

Pressure measurement is already used in a variety of situations. It provides information about gait mechanics and has a wide range of applications, i.e. in clinical situations and in sports. In this project the sensors are used to gain insight about weight distribution. Real-time visualization of pressure mapping is also incorporated because it makes it much easier to understand your data.
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.
