Add comprehensive documentation for all Arduino projects #1
Conversation
Created detailed README files for the repository and each learning project: - Main README with project overview and learning path - Lesson 1: Button controlled LED with circuit diagrams and concepts - Lesson 2: For loop LED sequence with code explanations - Stop Light: Traffic light simulator with interrupt handling - LED Distance: NeoPixel distance indicator with sensor integration Each README includes hardware requirements, wiring diagrams, code explanations, troubleshooting tips, and learning extensions. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
WalkthroughFive new README documentation files added to an Arduino learning projects repository. The main README provides project overviews and getting started guidance, while project-specific READMEs document four Arduino projects covering LED control, distance sensing, traffic simulation, and loop patterns.

20-22: Minor redundancy: "pin numbers" can be simplified to "pins".Line 21 uses "pin numbers" which is slightly redundant. Consider simplifying to "pins" for more concise prose.
- Demonstrates the use of for loops to control multiple LEDs in sequence. The sketch lights up 6 LEDs in order from low to high pin numbers, then reverses the pattern. + Demonstrates the use of for loops to control multiple LEDs in sequence.
