I still remember the day when I asked 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 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 a computer program, or IDE (Integrated Development Environment) that runs on your computer.
It requires a printer cable to connect the board to your laptop and needs software that is open-source, and easy to download from the Arduino official website. Make your circuit on a breadboard, and connect it to your laptop. Sketch code. Install board drivers. Select your port, and upload it on Arduino.
And the good thing about Arduino is its community; is always ready to help. Most importantly, you will get a lot of free libraries, and code in the community of Arduino.
Note: It’s better to start your Arduino journey with the LED blink code that would give you a basic understanding of the code and how it works.
2. What software is used in Arduino?
IDE stands for Integrated Development Environment – An official computer program presented by Arduino.cc, that’s primarily utilized for composing, compiling, and uploading the code in nearly all Arduino modules/boards. Arduino IDE is open-source software and is effortlessly accessible to download & install from Arduino’s Official Site.
Can we use IDE software with each and every module of Arduino?
As there is no such thing from the official Arduino makers that you need different software with different Arduino modules. It is recommended by the Arduino makers and can easily be used with each Arduino module if that’s Arduino Mega, or Arduino UNO.
3. What programming language is used to program an Arduino board?
Arduino code is composed in C++ with an expansion of extraordinary strategies and capacities. C++ could be a human-readable programming dialect. Once you make a ‘sketch’ (the title given to Arduino code records), it is prepared and compiled to machine dialect.
Arduino is built around a clear programming dialect that’s implied to be inviting to newcomers — but on the off chance that you’re truly brief on experience, it may be worth attempting a device like ArduBlock.
There are various languages where we can program an Arduino, but C++ is one of the most used languages by hobbyists, engineers, and researchers. Here’s a list of languages that you can program an Arduino:
- Python
- C#
- C++
- Snap4Arduino
- ArduBlock
The Arduino IDE is open-source software that allows users to program their board, and program library from the wiring projects, which gives numerous common input and yield methods. It runs on MAC OS X, Windows, and Linux.
4. What can I do with my Arduino?
Arduino boards are able to study inputs – light on a sensor, a finger on a button, and turn it into a yield – enacting an engine, turning on a Driven, distributing something online. You tell your board what to do by sending a set of information to the microcontroller on the board through IDE software.
There is no limit for your creativity, but here are some of the projects that are good to go. It has an extensive list of real-life examples:
- Construct a Modest Climate Show System.
- Build a Motion-Triggered Night Light for Utilizing Beneath Your Bed.
- Build a Framework for Quieting Any Express You Need on TV.
- Build an Ambilight Sensor for Your LCD Show.
- Build a Unique Mark Scanner for Your Garage Entryway Opener.
- Build an Automated Arm.
5. How to get started with Arduino?
In Arduino, both the boards and the IDE have made it simple for an era of individuals, to begin with, physical computing, mechanical technology, and for the most part playing approximately with programmable hardware.
Here are the exact steps you need to follow to start with Arduino
- Download the Arduino IDE. The most recent form of the IDE can be downloaded from the official site.
- Interface the USB cable to the Arduino.
- Confirm on the off chance that the Arduino board is recognized or not.
- Select the port if you are connected with the wrong port.
- Write your first outline.
- Compile your outline.
- Upload your outline
Congratulations! You have effectively uploaded your first sketch into the Arduino Uno!

6. What microcontroller is best: Arduino or Raspberry pi?
The main distinction between Arduino and Raspberry PI is; Arduino is a microcontroller board, while Raspberry Pi could also be a chip-based mini computer (SBC).
- Raspberry is faster than Arduino when we talk about software.
- Arduino’s straightforwardness makes it much superior than the raspberry pi, wage for immaculate equipment projects.
- Arduino is economical and easily available in the market where raspberry pi is more expensive than Arduino.
- You will get tons of free tutorials, and eBooks available on the internet.
- Arduino is preferred to handle single tasks while Pi could handle multiple tasks easily. It is recommended to use Arduino if you want a quick setup.
- Arduino does have a ‘real-time’ capability that the Pi. This adaptability permits it to work with close to any kind of sensor or chips.
7. Can I do any projects using an Arduino board?
If you love controlling things that you want them to then Arduino is one of the microcontroller boards that you would love. You can control everything from lights to motors to cars. (I know it can’t control your life)
Arduino is an open-source board which is great for hobbyists and electronics lovers like you. It has multiple types of boards that you can select according to your equipment or your end goal. Just like Arduino Lilypad is recommended for wearable objects, and Arduino Mega 2560 is recommended for 3d printers.
There are various projects you can do, and control things according to yourself, just like how you want to, but here are a list of projects you can go for:
- Squinting LEDs
- Activity light system the codes are displayed
- Serial Screen utilization
