What is Arduino and Why to use it

What is Arduino & How to Use it?

In this video, we will see what is Arduino and how to use it? First, let's understand a microcontroller.

Programmers work in a virtual world, while machinery works in the physical world. Now to combine both of these worlds, the microcontroller comes in to picture. A microcontroller is a kind of chip in which we upload program. It is a small-scale computer with generalized inputs & outputs.

You can say a microcontroller is one type of CPU. In this, microprocessor, RAM, and program memory exist. In the program, memory code is stored, and in RAM, inputs are stored. All these components combined in a system, which is known as 'Embedded System.' So, in an embedded system, the software is loaded into a hardware device.

As shown in the video, Arduino's definition states that it is an open-source electronics platform. It is easy-to-use for non-technical persons too. In the video, Arduino features are explained in detail. Arduino senses the environment and works according to it.

The video also shows the history of Arduino, how Arduino's name comes, and its other benefits. In Arduino, the programming language is very simplified. It uses C++'s simpler version.

Types of Arduino are classified based on the number of pins, size, processor it has. Like: Leonardo, micro, mega, uno, etc., let's talk about Arduino UNO. It is the first Arduino. Its detailed explanation is available in the video. You can see how many different pins come with it. Every pin's work is described in the video.

Now, let's understand Arduino MEGA.  It has more communication pins, more memory than UNO. You can understand some common sensors like sound, IR, temperature, etc., from the lecture and video clarifies the voltage sensor, ultrasonic sensor, and Bluetooth module.

What is Shields? Shields are circuit boards that extend the capabilities of Arduino. Examples of shields are Ethernet, GPS, motor, etc.

In short, Arduino is a low cost way to enter into the hobby of robotics. It has an extensive online library of code & projects.
