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.
Quickly install circuit-debugger AI skill to your development environment via command line

Common Power Issues: | Symptom | Likely Cause | Fix |
| No voltage anywhere | Disconnected power, blown fuse | Check continuity from source | | Low voltage (< 4V when expecting 5V) | Overloaded supply, bad regulator | Reduce load, check current draw | | Voltage drops under load | Undersized power supply | Calculate total current, upgrade PSU |
| Reverse polarity | Swapped wires | Check all connections, may have damaged components |
