Real projects you can build for real.
Pick a project, open it in the Studio to play, then take the shopping list to a real breadboard. Fifteen builds, from a first blinking LED to an Arduino-driven distance sensor.
Start with Tier 1. Each tier builds on the last.

Hands-on Labs — try it before you build the real thing.
Eight short sandboxes that drop you into a half-built circuit and ask you to finish it. Continuous feedback. Friendly hints. No wrong answer punishments.

Start Lab 1First Sparks
Everything you need to make a real LED glow with your own hands.
Light My First LED
Make a tiny light glow with a battery and a resistor.
Push-Button Light
Press a button to turn your LED on. Let go to turn it off.
Flashlight in a Box
Build a real, working flashlight you can take into a dark closet.
Series vs Parallel
Wire two LEDs two different ways and watch the brightness change.
Night-Light
A light that turns on automatically when the room gets dark.
Timer Magic
Meet the 555 — the chip that lets your circuit keep its own time.
Blinking LED (Hello, World)
A red light that blinks on and off, all by itself.
Two-Tone Siren
A police-car sound that rises and falls — built from two timer chips.
Touch Lamp
Touch a wire and the light stays on for 5 seconds, then turns off.
Light-Triggered Alarm
When a beam of light hits the sensor, the buzzer screams.
Adjustable Blink Speed
Turn a knob to make the LED blink fast or slow.
Code the Real World
Add a microcontroller, write a few lines of code, and your circuit listens, watches, and responds.
Traffic Light
Red, yellow, green — change in the right order, just like the streets.
Distance-Sensing Light
The closer you get, the brighter the LED glows.
Reaction Game
Press the button as fast as you can when the light flashes. See your time.
Plant-Watering Reminder
Stick the probe in your plant. When it’s too dry, the buzzer beeps.
Mini Theremin
Wave your hand over the sensor to play different notes — like a magic instrument.
Saves Lives
Six ambitious projects that show how the things you’re learning can matter for someone’s safety.
Six ambitious projects that connect what you’ve been learning to something that matters: a flood alarm, a vaccine fridge monitor, an earthquake detector, an air-quality light, a medication reminder, and a turn-signal vest.
They unlock once you’ve marked 5 First Builds as built — or finished all 8 Hands-on Labs. Either path works.
