You must have heard about the microcontroller board from engineering students, because it is the most popular microcontroller board among students, and hobbyists, and as of 2020, there were 30 Million active users according to the Arduino IDE downloads.
That’s nearly one-eighth of the entire world population.
I worked tirelessly to control things, and I liked it. How would you feel if you could control something? Who doesn’t enjoy being in power?
I liked it and controlled everything that I wanted to if I talk about the sensors, or robotic arms, or robotics car. I did it all.
But before you move ahead and buy an Arduino, here are a few common Arduino questions to ask yourself before you get your hands dirty in coding, and wires.

Common Arduino Questions To Ask Yourself
What is an Arduino?
In technical terms, an Arduino is a single-board microcontroller.
But in nontechnical terms?
A credit card-sized circuit board with input and output pins that can snare up different other electronic components using wires; resistors, driven diodes, motors, fans, buttons, speakers, sensors, and more! It’s basically Lego Mind storms for grownups.
The Arduino board is famous among beginners who are starting out with electronics, and for significant reasons. First, they are not as costly as other boards like raspberry pi, and other advanced boards. Second, you can get free resources, and codes from the Arduino community. Last, the Arduino does not require any specialized coding expert (called a software engineer) in order to stack modern code onto the board.
The Arduino IDE employs a disentangled version of C++, making it easier to memorize and program. At long last, Arduino gives a standard shape calculation that breaks out the capacities of the micro-controller into a more open bundle.
The Arduino board is the brain, and you’ll be able to blend and match the different components you need to make anything you need, and after that program the board to create yields based on inputs (e.g. Press a button to turn on an engine).
Is there any community available on the internet that helps Arduino users?
Community is an integral part that can help a beginner to overcome all the issues and errors faced during the Arduino project. It can allow us openings to associate with individuals, to reach for our objectives, and makes us feel secure and secure. Each individual needs to have a sense of community.
There are multiple forums present that allow beginners to get help from experts. You can ask questions and get expert advice. The forums are
What Arduino board should I choose?
As Arduino is an open-source board anybody can make it on their own. There are a lot of boards available within the advertisement just like the FreeDuino and NetDuino.
Now you might think about how to distinguish between the other boards and the original boards?
Don’t worry.
One way to distinguish between unique boards and consistent models is to seek the exchange title on the board. The title Arduino is trademarked and saved for sheets made from the first obvious company in Italy.
If you are a beginner, and thinking of getting started with these boards, then I would recommend you to buy the Arduino UNO R3. Otherwise, you can also purchase clone boards like Freeduino. It has 14 computerized pins and 6 Analog pins. So you’ve got up to 20 GPIO pins (Common Reason Input-Output pins), which is sufficient for most of the newbie and halfway level Projects.
To summarize, an Uno is recommended for little and basic Arduino Projects depending upon your measurements and fetched limits. Or in case you’ve got a requirement for a more prominent number of pins or serial communication devices to be processed with the same controller you’ll go for the Arduino Mega. It is recommended for 3d printers.
Recommended Reading: Beginners often get confused in selecting the right board for their project, and it is the hardest part. I got also confused when I started out in Arduino. So I made a guide about the best Arduino board, and how to select them for your project.
Difference between Arduino and Raspberry Pi?
Both Arduino and Raspberry Pi are great educational instruments for understudies, hobbyists, and specialists. Let us see a few of the contrasts between Raspberry Pi and Arduino. The fundamental contrast between them is:
- Arduino is a microcontroller board, whereas Raspberry Pi could be a chip-based smaller than expected computer (SBC).
- The Microcontroller on the Arduino board contains the CPU, SRAM, and ROM. All the extra equipment on the Arduino Board is for control supply, programming, and IO networking. Raspberry Pi SBC has all the highlights of a computer with a processor, memory, capacity, illustrations, driver, connectors on the board. Raspberry Pi needs a Working Framework to run. Arduino doesn’t need any operating framework.
Raspberry Pi comes with a completely utilitarian working framework called Raspberry Pi OS (previously known as Raspbian OS). Even though Pi can use diverse working frameworks, Linux is favored by the Raspberry Pi Establishment.
The Raspberry Pi is 40 times speedier than an Arduino when it comes to clock speed. It might sound like Raspberry Pi is predominant to Arduino, but that’s when it comes to program applications. Arduino’s effortlessness makes it much superior for pure hardware projects. So you should go for Arduino.
Recommended Reading: Raspberry Pi is one of the most famous boards after Arduino. And it is an advanced board if we compare it with Arduino boards and the Arduino family. So here are the detailed difference between Arduino and raspberry pi so you don’t get confused in selecting the right board.
What is the cost of the Arduino and Arduino starter kit?
Arduino and Arduino’s starter is a great way to start your electronics career and is not very expensive. A great Arduino starter kit will cost beneath $100, and an Arduino board for under $25.
The Arduino board itself won’t be enough for you to make such projects that can make you happy, so you are going to buy some electronics components that are essential for you to work on the projects such as resistors, LEDs, servo motors, capacitors, and many others from an online marketplace.
As the Arduino hardware design is an open-source, and many other local companies try to sell locally made boards that are somehow helpful to when you are just starting out as a beginner. But I would recommend you to buy original trademarked Arduino boards or go for some famous local manufacturers.
You can easily get locally manufactured Arduino for under $15.
I can suggest some sites from where you can buy at a reasonable price. For beginners and hobbyists of Arduino. The best places to get your Arduino and starter kit are:
- Amazon
- USA store
- Pololu
- Robotistan
- Ali Express
- Amazon store
How hard is it to learn Arduino?
Arduino is the best platform to introduce your kids to the whole new world of electronics, wires, and programming. Arduino, a microcontroller type, is open-source. It is easily accessible – even if you are a beginner or a hobbyist, or you have a homeschooling kid at your home.
In the simplest form, an Arduino reads the data input from the sensors and converts these inputs into output. Programming, hardware, and components; that’s what you’ll be able to expect from utilizing an Arduino.
- Connect cables?
- Plug-in components?
- Use a keyboard?
These three would be the basic tasks to do in an Arduino-based project, and if you think you can handle all three, then it would be so easy to tackle the Arduino project situation. In case you’ve never dealt with wires, and breadboards, at that point this is often a secure and fun way to learn.
Most Arduino starter packs come with LEDs, resistors, capacitors, accelerometers, Arduino boards, buttons, shows, and more. You’ll feel like a kid playing with Lego pieces all over once more. There is also coding that you can learn with time, and project to project. So you don’t need to worry about a few mistakes in the beginning.
Protip: I would recommend you do some research about Arduino and spend some time on YouTube while learning Arduino.
Where can I buy Arduino components?
Arduino itself won’t be enough to work on your project and to get the hands-on projects you need components that fit the best with Arduino such as resistors, capacitors, Arduino shields that can drive motors or connect Wi-Fi.
You’ll discover many Arduino-related shops within the world, but there are moreover several suppliers that are great to know almost when shopping for the correct parts and components.
Here are 10 places to find Arduino parts and components.
- RS Components (World)
- Farnell (World)
- Rapid (World)
- Digi-Key (World)
- Maplin (U.K.)
