Generate Arduino/embedded C++ code snippets and patterns on demand for UNO/ESP32/RP2040. Use when users request Arduino code for sensors, actuators, communication protocols, state machines, non-blocking timers, data logging, or hardware abstraction. Generates production-ready code with proper memory management, timing patterns, and board-specific optimization. Supports DHT22, BME280, buttons, I2C/SPI, EEPROM, SD cards, WiFi, and common peripherals.
Build complete, production-ready Arduino projects (environmental monitors, robot controllers, IoT devices, automation systems). Assembles multi-component systems combining sensors, actuators, communication protocols, state machines, data logging, and power management. Supports Arduino UNO, ESP32, and Raspberry Pi Pico with board-specific optimizations. Use this skill when users request complete Arduino applications, not just code snippets.
Systematic hardware debugging guide for Arduino/ESP32/RP2040 circuits. Use when user reports: circuit not working, components getting hot, no power, intermittent failures, unexpected behavior, sensor not responding, LED not lighting, motor not spinning. Guides through power checks, continuity testing, signal tracing, and component isolation using multimeter techniques.
Interprets Arduino/ESP32/RP2040 compiler errors in plain English for beginners. Use when user shares error messages, compilation failures, upload problems, or asks "what does this error mean". Covers common errors like undefined references, type mismatches, missing libraries, and board-specific issues.
Auto-generates professional README.md files for Arduino/ESP32/RP2040 projects following open-source best practices. Use when user wants to document their project for GitHub, needs help writing a README, or says "make my project shareable". Follows awesome-readme standards with sections for Overview, Hardware, Software, Setup, Usage, Troubleshooting, and Contributing.
