The author has made an attempt to present a collection of questions on Arduino Projects MQA.
Arduino Projects MQA
1. What is the Arduino used for?
Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino is 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 and many more.
2. Is Arduino based on C or C++?
Yes, Arduino language is C++, but it is very different from most C++ varieties.
3. Which software is used for Arduino?
Arduino IDE is used to write code and upload it to the board. It runs on Windows, Mac OS X, and Linux.
4. Is Arduino a programming language?
The Arduino Programming Language is basically a framework built on top of C++.
5. Is Arduino a microprocessor?
An Arduino is based on a microcontroller which is a easy to use computer designed for beginners to run 1 program at a time, over and over again.
6. What language is Arduino?
Arduino code is written in C++ with an addition of special methods and functions.
7. Can you use Python on Arduino?
No, it’s possible to use Arduino with Python or another high-level programming language.
8. Is Arduino worth learning?
Arduino is a fun way of understanding embedded systems. So, yes it is worth learning Arduino because from the coding and wiring you’ll pick up some knowledge from developing some project of yours.
10. Is Arduino a Java?
The Arduino IDE – the software we use to program your Arduino, is written in Java.
11. Why is Arduino so popular?
Arduino hardware is easy and IDE is simple, and the code itself is much easier. It is also cheaper than other microocontroler
12. How many types of Arduino are there?
There are different types of Arduino boards
- Arduino UNO
- Nano
- Mega
- Leonardo
- LilyPad Arduino
- Arduino Bluetooth
- Arduino Diecimila
- RedBoard Arduino Board
- Robot Esplora Pro Mic
- Ethernet
And many more !
13. Who invented Arduino?
Massimo Banzi, David Cuartielles, Tom Igoe, Gianluca Martino, and David Mellis started the Arduino project.
14. What does == mean in Arduino?
Comparison operator [ == ], which means whether two expressions are equal.
15. Is Arduino a computer?
No, it is a programmable microprocessor or microcontroller.
16. What’s the difference between Arduino and Raspberry Pi?
The main difference between them is Arduino is microcontroller board while raspberry pi is a mini computer.
17. Is Arduino an embedded system?
Yes, Arduino is one of those Embedded System Devices, which got very famous in the maker’s community due to its free and open source nature
18. What is Arduino API?
The arduino rest api is a mechanism to exchange data between arduino and other external systems.
19. Which language is best for Arduino?
C and C++ as they are very close to hardware and have lots of library.
20. Why Arduino is used in IoT?
Arduino acts as the brain of the system and processes the data from the sensor. And you need to use ESP-8266 WiFi module to establish the WiFi communication between the Arduino and cloud platform.
21. Which Arduino has WiFi?
The Arduino Uno WiFi is an Arduino Uno with an integrated WiFi module.
22. What is the cost of Arduino Uno?
Approximately Rs 300 to 400.
23. Why is Arduino called Arduino?
The name Arduino comes from a bar in Ivrea, Italy, where some of the founders of the project used to meet.
24. Can you run Windows on Arduino?
An Arduino can be programmed with standard C/c++. The big difference between an Arduino and a Windows PC (which can also be programmed with standard C/C++) is that the Windows PC will have 2GB of RAM and the Uno has 2k and the Windows PC probably runs at 1.6GHz whereas the Uno runs at 16MHz.
25. Is Arduino good for IoT?
Yes, you can use IoT if you are a beginner.

26. How fast is Arduino loop?
The loop will execute at a speed of about 117 kHz. This means that everything you put into a void loop() , your Arduino will execute about 117,000 times/ second.
27. Why we should use Arduino?
We should use Arduino because of its features:It is easy to use.
It runs on a Cross-platform.
Low cost
I t is open source.
28. Write some advantages of Arduino.
It able to read analog or digital input signals.
We can control our functions.
It uses c and c++ programming language.
29. What are Libraries in Arduino?
In Arduino, Libraries are collection of code that makes it easy to connect to a sensor, display, module etc.
30. What is sketch in Arduino?
In Arduino, the first terminology is the program called sketch.
Hope this collection on Arduino Projects MQA shall help students for Interview. Any suggestion on the topic is welcome.
