Arduino
Arduino is a popular tool used to create electronic projects and small robots. Think of it as a mini-computer on a small board that helps makers and engineers bring their ideas to life. It's particularly useful for creating prototypes and learning about electronics. Arduino makes it easier for people to build things like smart home devices, robot controls, or automated systems without needing deep electronics knowledge. Similar platforms include Raspberry Pi and BeagleBoard. Arduino is often mentioned in job descriptions when companies need someone who can work with physical electronics and basic programming together.

Example Interview Questions
Senior Level Questions
Q: How would you manage a large-scale Arduino project with multiple devices?
Expected Answer: A senior candidate should discuss project planning, communication between devices, scalability considerations, and how to organize teams working on different parts of the system.
Q: What safety considerations do you implement when designing Arduino-based systems?
Expected Answer: Should explain basic electrical safety, fail-safes, proper power management, and how to protect both the device and users in various scenarios.
Mid Level Questions
Q: How do you troubleshoot an Arduino project that isn't working as expected?
Expected Answer: Should describe a systematic approach to finding problems, including checking connections, testing code parts separately, and using tools to measure electrical signals.
Q: Explain how you would connect an Arduino to the internet securely.
Expected Answer: Should discuss different ways to connect Arduino to the internet, basic security practices, and how to protect data being sent and received.
Junior Level Questions
Q: What basic components have you worked with on Arduino projects?
Expected Answer: Should be able to describe common parts like LEDs, buttons, sensors, and basic projects they've built with these components.
Q: How do you make an LED blink using Arduino?
Expected Answer: Should explain the basic process of connecting an LED and writing simple code to make it turn on and off - this is the 'Hello World' of Arduino projects.
