In the Light World you explore simplified virtual circuits on a 3D workbench. Here are the parts you will meet.
🔋 Battery — Powers your circuit. The + side is positive, the - side is negative.
💡 LED — A tiny light. Connect the long leg (+) to the battery's + side.
🎚 Switch — Open or closed: lets current pass or stops it.
🔘 Button — Hold it down to let current pass.
🟫 Resistor — Limits the amount of current. Helps protect parts such as LEDs.
🌈 RGB LED — A light that can change color. Has Red, Green, Blue legs.
Battery: Hi friend! I'm Bora the Battery. I'm full of energy!
Battery: I have two sides — a plus (+) and a minus (-). Electricity flows from + through the circuit and back to -.
LED: And I'm Lila the LED! My long leg is + and my short leg is -. Match them up with Bora the right way and I'll light up!
Guide: Drag Bora and Lila to the table. Tap a pin on Bora, then a pin on Lila to wire them up. Match + to + and - to -.
Switch: I'm Anya the Switch! I can OPEN or CLOSE the road for electricity.
Switch: When I'm OPEN — no electricity gets through. When I'm CLOSED — it flows!
Guide: Place me between Bora and Lila. Tap me to flip me open or closed.
Guide: Want to light up many LEDs at once? Wire each LED to the battery's + and - separately. This is called a PARALLEL circuit.
