This beginner-friendly guide shows you how to convert an ordinary desk lamp into an integrated, ESPHome and Home Assistant-powered smart lamp using the Raspberry Pi Pico 2W. By switching to a safe, low-voltage DC setup (using a 12V DC LED bulb, buck converter, and relay module), the build avoids mains AC wiring while keeping all the smart logic built directly into the lamp. The tutorial walks through the hardware component list, circuit wiring, soldering, and ESPHome YAML configuration required for seamless home automation integration.
