How should I learn programming and electronics for a beginner robot project?
Asked by

I'm trying to learn programming, but I've struggled to stay motivated with introductory computer science courses because the material feels difficult and disconnected from the things I want to build. Tutorials also tend to leave me stuck when I run into errors I don't understand.
I'd like to use a small robot project as a long-term goal: a machine that detects my face, controls servo motors, and launches or dispenses cigarettes toward me. The idea is intentionally silly, but it would give me a reason to learn computer vision, programming, motor control, and basic hardware. For safety, I'm open to starting with a harmless alternative, such as dispensing or moving an object instead of firing a projectile.
What fundamentals and resources should I focus on first? My biggest weakness is troubleshooting, since I don't yet understand enough programming or electronics to diagnose problems effectively.

Finishing an introductory course would probably help, especially with debugging and problem-solving. You don’t need to love every exercise, but the fundamentals are what let you understand error messages, test assumptions, and find out which part of a program is failing. When stuck, reduce the problem to the smallest possible example, read the exact error, test one change at a time, and write down what you expected versus what actually happened. Don’t rely only on brute force or copying fixes from searches.

A practical learning path could be: basic Python, then simple command-line projects; basic circuits and electrical safety; a beginner microcontroller such as an Arduino for sensors and servos; and finally a small computer such as a Raspberry Pi for camera input and face detection. Keep each stage independent and document the wiring, code changes, and errors. For the mechanical part, start with a safe target, a light foam object, or a non-launching dispenser rather than anything that could hit someone’s eyes or face.

A project goal is useful motivation, but this one combines several advanced topics: programming fundamentals, electronics, motor control, computer vision, and mechanical design. Trying to build the complete version immediately will probably be overwhelming. Work upward in small stages: learn basic programming, write simple programs, control one LED, read a sensor, move one servo, and only then combine those pieces. Also consider making it dispense or point at an object rather than launch anything, since projectiles can cause injuries.
MellowKite47: That makes sense. I’ve been treating the final idea like a first project instead of breaking it into smaller milestones. I’ll try to build the simpler pieces one at a time.

LimeWindow6: Getting stuck on a difficult assignment for weeks can be a sign to ask for help or temporarily switch topics, not necessarily to abandon all the fundamentals. Returning with a smaller practice problem may make the original material easier.
