Prompt: Interactive ESP32-C3 LED Circuit Dashboard

Build a single-page interactive web dashboard that teaches how current flows when an ESP32-C3-DevKitM-1 dev board is wired to a breadboard, a pushbutton switch, and an LED. Accuracy matters more than decoration — this needs to be electrically correct, not just pretty.

1. Research first

Before writing any SVG, look up and use as reference:

• The official Espressif ESP32-C3-DevKitM-1 pinout diagram (silkscreen labels, pin count per side, USB-C port, BOOT/RESET buttons, onboard RGB LED location).

LLM Wiki

A pattern for building personal knowledge bases using LLMs.

This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.

The core idea

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.

My Claude Code Setup Guide (macOS)

A step-by-step guide to installing and configuring Claude Code on macOS, the way I use it. This isn't meant to be the definitive reference -- it's just my personal setup that's been working well for me. Things change fast, so if something looks off, check the official docs or let me know.

Common Terminal Commands

Key Commands & Navigation

Before we look at some common commands, I just want to note a few keyboard commands that are very helpful:

• Up Arrow: Will show your last command
• Down Arrow: Will show your next command
• Tab: Will auto-complete your command
• Ctrl + L: Will clear the screen

bholmesdev

• /grill-me for research and planning
• /taste-review to let Codex make more tasteful design decisions by asking Claude (you'll need the claude CLI installed for this)
• /vercel-react-best-practices for improving the quality of React component these agents generated
• /simplify to improve code quality, reduce comment wordiness, and improve system architecture
• /test-desktop-app to test Electron apps end-to-end. If you work on a different kind of app, write your own version!
