What is arduino and how it works?

Arduino is an open-source electronics platform based on easy-to-use hardware and software. It’s intended for anyone making interactive projects. Arduino boards are able to read inputs – light on a sensor, a finger on a button, or a Twitter message – and turn it into an output – activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do this you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing.

How does Arduino work?

Arduino is an open-source electronics platform that can be used to create interactive electronic projects. The hardware consists of an Arduino board, which includes a microcontroller and input/output (I/O) pins, and a variety of sensors and actuators. The software consists of the Arduino IDE, which is used to write sketches, or programs, that are uploaded to the microcontroller.

Sensors are devices that convert physical quantities, such as temperature or light, into electrical signals that can be read by the microcontroller. Actuators are devices that can be controlled by the microcontroller, such as motors or LEDs. Sketches can be written to read inputs from sensors and control actuators accordingly. For example, a sketch could use a temperature sensor to control the speed of a fan, or use an LED to indicate whether a door is open or closed.

Arduino boards can be connected to each other and to computers and other devices using various communication protocols. For example, boards can be connected over a serial port, USB, or Ethernet. This allows for the creation of larger and more complex projects. Arduino boards can also be powered by a variety of sources, including batteries, solar panels, and USB.

Arduino is a versatile platform that can be used for a wide range of applications. Some common applications include home automation, robotics, and wearables. Arduino is also being used in education to teach students about electronics and programming.
