projects

Build something real.

Every project explains why the circuit works — actual numbers, not magic — and ends with a challenge that has more than one right answer.

L1 Light

Your first circuits — make light happen.

First Light Build a real flashlight circuit and learn why every circuit is a loop. 15 min · ●○○○○ Morse Code Messenger A push button, an LED, and a secret code — send real messages with light. 20 min · ●○○○○ Tabletop Traffic Light Three LEDs, three parallel lanes — build a traffic light and discover parallel circuits. 25 min · ●●○○○ The Brightness Lab Run a real experiment: predict, measure with your eyes, and prove Ohm's law. 30 min · ●●●○○

L2 Sound

Add noise. Doorbells, alarms, annoying siblings.

L3 Sense

Circuits that react to the world around them.

Automatic Night Light A light that switches itself on when the room gets dark — no hands, no code. 35 min · ●●●○○
