What are some typical challenges contract Arduino programmers face when working with clients on short-term projects?

Contract Arduino programmers often encounter challenges such as unclear project specifications, tight deadlines, and limited access to client hardware for testing. Communication is key, as clients may not always have a technical background, making it important to clarify requirements and expectations early. Additionally, contract programmers must be adaptable, frequently troubleshooting hardware and software issues independently while ensuring that their code is well-documented for client handover.
