I still remember the day when I asked a simple questions about the Arduino in the auditorium, and how everyone laughed at me, if I had asked a silly question; that was relevant to the topic, but they still laughed.

It wouldn’t be easy for me to come out of that situation, but I had to. I know how it felt; bad.

That’s why I compiled 13 Arduino questions that you had never asked from your friends and teacher because of your insecurities, and fear of being a victim of that.

Before we move forward you should know Arduino is a community of 30 Million active users according to the Arduino IDE software downloads, based on the 2020 stats. That’s nearly 0.5% of the whole population in the world.

That’s how big the Arduino community is. Let’s dig deeper with the Arduino; what is it? And there are pretty amazing resources mentioned by the end of this blog you will get tons of ideas to work on.

1. What is an Arduino and how does Arduino work?

Arduino is an open-source microcontroller board based on easy-to-use equipment and programs. Arduino boards can examine inputs – light on a sensor, a finger on a button and turn it into an output – actuating an engine, turning on a Led, distributing something online.

Arduino comprises both a physical programmable circuit board (regularly alluded to as a microcontroller) and a bit of computer program, or IDE (Integrated Development Environment) that runs on your computer.

It requires a printer cable to connect the board with your laptop and needs software which is an open source, easy to download from the Arduino official website. Make your circuit on a breadboard, connect it with your laptop. Sketch code. Install board drivers. Select your port, and upload it on Arduino.

And the good thing about the Arduino is it’s community; always ready to help. Most importantly, you will get a lot of free libraries, and code in the community of Arduino.
