Parts lab
Know the component before you place the wire.
A visual component guide for symbols, polarity, meter checks, common mistakes, and where parts appear in the builds and lessons.
Safety first, always.
ElectroLab AI teaches theory, low-voltage electronics, and planning concepts. Mains voltage, switchboards, fixed wiring, high-current systems, and legal electrical work must only be performed by licensed electricians where required.
