Q: Who should take the exam?
A: Anyone interested in engaging with Arduino through a process that involves study, practice and project building.
Q: Why take the exam?
A: Obtain a certification that validates your understanding of the Arduino building blocks, such as the basics of physical computing, electronic circuits, programming, prototyping, and mechatronics. These are skills in high demand from both universities and employers.
Q: How is the Arduino Fundamentals exam structured?
A: The exam is web-based and consists of 36 questions in various formats that cover a range of Arduino-related topics. You get 75 minutes to complete the exam, and can freely navigate back and forth between the questions and editing your answers. Once the exam is submitted, your answers will be assessed immediately. To avoid a loss of your answers, please use only the exam navigation arrow buttons, and / or the left navigation panel. Do not use the browser back and forward buttons during the exam.
Q: What topics are covered in the exam?
A: You will encounter questions that test your knowledge in relation to 8 main categories:
  1. Electricity. Understanding concepts such as resistance, voltage, power and capacitance, being able to measure and calculate them.
  2. Reading circuits and schematics. Understanding how electronics are represented visually, and the ability to read and analyze electronic circuits.
  3. Arduino IDE. Understanding the functionality of the Arduino development environment, serial communication, libraries and errors.
  4. Arduino Boards. Understanding the constitution and capabilities of an Arduino board and the functions of its different parts.
  5. Frequency and Duty cycle. Understanding the concepts of Pulse Width Modulation (PWM) and frequency, being able to calculate duty cycle.
  6. Electronic components. Understanding how various electronic components such as LEDs, sensors, buttons and motors work, and how to use them in a circuit.
  7. Programming syntax and semantics. Understanding the building blocks of Arduino programming language such as functions, arguments, variables and loops.
  8. Programming logic. Ability to program various electronic components, read, analyze and troubleshoot Arduino code.
Q: What are the exam’s prerequisites?
A: There are no specific prerequisites for completing before taking the Fundamentals exam. However, the knowledge level and concepts tested in the exam closely match the content of the Arduino Starter Kit. We can therefore recommend going through the content of the Arduino Starter Kit Projects book, and building the projects introduced in it.
Q: Can I pass the exam without any exposure to the Starter Kit?
A: Yes, it is possible to pass the exam if you have a thorough knowledge of the basic concepts of electronics and physical computing specifically related to Arduino.
Q: Am I required to take the exam in English?
A: The exam is currently available in English, Spanish, German, Chinese, Greek and Italian. Before starting the exam, you will be taken to a 3 step verification process to ensure your certificate is personal to you. On that page, you can also select the language you want to take the exam; please note that once you select it, you CANNOT change it during exam.
Q: What are the technical requirements to complete the exam?
A: You will need a computer and a stable internet connection. Avoid taking the exam at coffee shops or where wireless access is inconsistent. Please make sure to resolve any computer malfunctions, and to take all measures needed to reduce and prevent power outages before taking the exam.

Q: How do I purchase the exam?
A: Purchasing the exam alone (currently available worldwide except Brazil) costs $30.00 and grants 1 (one) attempt at the Arduino Fundamentals exam.
Purchasing the bundle (currently available worldwide except Brazil) for $109.90, will grant you the Arduino Starter Kit and an activation code, which can be used to unlock one (1) attempt at the Arduino Fundamentals exam.
Q: I haven’t received my invoice or my activation code. How can I request a copy?
A: You should receive an email with your invoice and activation code as soon as you purchase the Arduino Starter Kit +Exam bundle. Also, please check your spam folder if you don’t receive this email, and contact support at
Q: Does the activation code expire?
A: No, the activation code doesn't expire, you decide when to take the exam. As long as the ACP platform is available and you haven't used the activation code, you are free to activate it whenever you want. However, once the activation code has been used it will expire.
Q: Can I get a refund for the exam?
A: The Fundamentals exam is non-refundable, and non transferable. If you purchase the exam and decide not to pursue it, your purchase is non-refundable. We do not offer refunds for failed exams or expired attempts either.
No refunds are available since you have immediate access to the exam upon purchase.
Q: Can I return the Arduino Fundamentals Bundle and get a refund?
A. You can return the Starter Kit within 30 (thirty) calendar days from the date of the bundle receipt only if the code has not been activated.
