Electronics 101

Build nine circuits in Tinkercad, from a single AA cell to a micro:bit aiming a servo, then rebuild the last five with real parts. You build each one from a printed diagram first — we talk through what’s happening in it after it’s already working, not before. Foundational material shared across courses, not specific to any one class.
