Describe
Say it in plain language — no datasheets, no pinout tables. The parser figures out the parts, the board and the behavior.
Describe it.
Wire it. Build it.
Tell the workbench what you want to build. Get firmware, a wiring diagram, a parts list and step-by-step assembly from idea to blinking hardware in one sitting.

My monstera got its own pump last night. Soil probe → relay → tiny fountain of life. Total bench time: 40 minutes.

The wiring diagram alone is worth it. Color-coded jumpers meant zero magic smoke on the first power-up. A personal record.

Built the parking pal for my dad's garage. He reversed in, it beeped, he saluted the breadboard. Mission accomplished.

Kid presented their RFID badge, the chest clicked open, absolute chaos of joy. Best birthday build yet.

Went from 'I should learn microcontrollers' to a working focus timer on a Pico in one evening. The exported PlatformIO project just… flashed.

The desk buddy's OLED face judges me when I skip breaks. I built my own accountability. No regrets. Some regrets.

Swapped the Uno for an ESP32 mid-chat and it re-allocated every pin without complaint. That's the feature, honestly.

Night light fades on at dusk exactly like the steps promised. My hallway has never been this smug.
