Top 10 Interview Questions for Arduino

Interviews for Top Jobs at Arduino

Senior Product Designer Interview


I applied online. I interviewed at Arduino


I did 3 interviews, with the HR manager, Lead Designer and Product Owner.After 3 interviews (around 3 hours of total time) they didn’t provide feedback.No feedback (Negative or positive) after 3 interviews it’s a bad approach for some professional people that are investing time and effort in the interview.

Interview Questions

  • General questions about the working experience. Questions about working with and collaborating with other members of the product team, such as the PO and PM, as well as questions about UX and UI

Senior UX Designer Interview


I applied online. The process took 3 months. I interviewed at Arduino (Paris) in May 2021


A 3 month wait to let me know the position was closed is as bad as it gets, they need to either speed up or figure out what they want before wasting applicants’ time.

Interview Questions

  • Why do you want to work for Arduino?

One of the most well-known Arduino models, the Arduino Uno, is frequently used as a starting point for people who are unfamiliar with Arduino. It is a microcontroller board based on the ATmega328P. It has a USB port, a power jack, an ICSP header, and 14 digital input/output pins. It also has a reset button. It is a good option for projects that don’t require a lot of power because it is fairly easy to use.

Using the Arduino’s built-in LED blink example sketch is the simplest way to create an LED blink program. Open the Arduino IDE and select File > Examples > 01 to get started. Basics > Blink. This will launch a new sketch containing the code required to make an LED on pin 13 of the Arduino board blink. All you have to do to get a functioning LED blink program is upload this sketch to your board.

There are a number of real-world applications for Arduino. To control lights, appliances, and security systems, for instance, it can be utilized in home automation systems. It can also be used to keep an eye on and manage equipment in industrial settings. Additionally, numerous projects involving art and design have employed Arduino.

The Arduino board, the IDE, and the libraries make up an Arduino project’s essential elements. The equipment you’ll use to make your project is the Arduino board. You will write your code in the IDE and upload it to the board using this program. You can use the libraries to make your project easier to complete or to add new functionality.

Popular open-source electronics platform Arduino is used by makers, hobbyists, and programmers to create interactive electronic projects. If you’re applying for a job that uses Arduino, your interviewer is probably going to ask you questions about the platform. You can increase your chances of getting hired by impressing the hiring manager with your assured responses to these questions. In this article, we go over some of the most frequently asked questions about Arduino and offer advice on how to respond to them.

Arduino Interview Questions for freshers experienced :-

1. What is Arduino? Arduino is an open source electronic platform. It is based on easy-to-use hardware and software. It able to read input signal. Using Arduino, it is used to create and upload computer code to the actual board.

2. What version of the Arduino software is considered stable? It is version 1 8. 3 and released on 31 may 2017.

3. Who created Arduino? Arduino is the creator of Arduino.

4. We should use Arduino because of the following characteristics:

  • It is easy to use.
  • It runs on Cross platform.
  • Low cost
  • It is open source.
  • 5. What languages were used to create the Arduino software? The Arduino software was created in the Java, C++, and C languages.

    6. What are Arduino’s benefits? The features of Arduino include the following:

  • It able to read analog or digital input signals.
  • We can control our functions.
  • It uses c and c++ programming language.
  • 7. What are the IDE toolbars for Arduino? They include the following:

  • It is used to check if there is any compilation error.
  • It is used to upload a program to the Arduino board.
  • Shortcut used to create a new sketch.
  • It is used to directly open one of the example sketch.
  • It is used to save your sketch.
  • Serial monitor used to receive serial data from the board and send the serial data to the board.
  • 8. What does Arduino’s first terminology, the program referred to as sketch, mean?

    9. What are the three crucial components of Arduino? They are the structure, the values (variables and constants), and the function.

    10. There are two primary software structure functions, and they are as follows:

  • Setup( ) function
  • Loop( ) function
  • 11. The purpose of the operator in Arduino is to compile logical or mathematical functions.

    12. How do we declare the functions? We can do so by using the following code:

    int sum_func (int x, int y) // function declaration {

    return z; // return the value

    13. Which function is used to determine the length of a string? The strlen() function.

    14. How to convert string to upper case? The my_str. toUpperCase() function is used to convert string to upper case.

    15. There are four functions of time in Arduino, and they are as follows:

    delayMicroseconds() :

    16. Libraries are a collection of code that makes it simple to connect to a sensor, display, module, etc. in Arduino.

    The primary Arduino used the Atmega8, which could only operate at 16 MHz, as the cause. Due to the upgraded chip, they wanted to ensure that the boards’ velocity was appropriate. Additionally, since Arduino is only eight bits and no longer just intended for immediate processing, the chips are operating at 16MHz.

    For physical computing, there are numerous additional microcontrollers and microcontroller platforms available. Similar functionality is provided by MIT’s Handyboard, Parallax Basic Stamp, Netmedia’s BX-24, Phidgets, and a number of other applications. These tools all combine the messy microcontroller programming details into one easy-to-use package. Additionally, Arduino makes using microcontrollers simpler, but it has a few advantages over alternative systems for educators, college students, and involved amateurs.

    Create your own name if you’re making your own board; this will help people associate you with your goods and enable you to create a logo. Be imaginative; try to think of possible uses for the board, or emphasize its shape, or just choose a random word that sounds cool. The term “Arduino” must no longer be used for unofficial versions as it is a trademark of Arduino LLC. Please visit the So you want to make an Arduino record and contact the Arduino group if you are interested in having your design included in the professional Arduino product line. Unofficial merchandising must not use the word “Arduino” in their name, but it is acceptable to mention the Arduino platform and assignment in your product description. Here are a few suggestions that list reasonable uses that we shouldn’t forget.

    Yes, alternative serial video display units may be used. Through a digital serial port over USB, the Arduino communicates with the computer. This makes it possible for any program on your computer to connect to the Arduino. Not to mention the fact that you could use the serial port to create your own packages that could speak for your project.

    Giving beginners access to an entire ISP programmer will result in bricked chips. Backwards compatibility – the Arduino chips can still be programmed with FTDI breakout boards or cable Having the chip act only as a USB/serial passthrough simplifies the firmware so that the chip has only one feature instead of getting to have it do double duty as programmer – and- serial interface (reflect onconsider on it, its not smooth) Wipro Java Interview Questions Question 33. So Does This Mean There May Be An Arduino Shortage?.
