Build real circuits on your iPad — wire a breadboard, write real code, watch it light up. 15 hands-on lessons from your first blink to sensors, sound, and servos.

Learn how electronics really work — by building them. Turn your iPad into an electronics lab: wire up a breadboard, drop in LEDs, sensors, buzzers, servos and a microcontroller, write real embedded C, and watch your circuit come to life. No kit to buy, no loose wires, nothing to fry.

15 hands-on lessons take you from your very first blinking LED to reading sensors, mixing colours on an RGB LED, playing melodies on a buzzer, sweeping a servo, and building a light-sensing night light — each with a clear goal the app checks for you as you go.

• Write real code — the same C you'd run on actual hardware, interpreted live on your iPad • See electricity flow — a faithful circuit simulation: wire it wrong and it won't light up, exactly like real life • Wire it yourself — tap two points to connect them, drag components onto the breadboard • Learn by doing — guided lessons with goals, hints, and instant feedback

Unlock Pro to open the Sandbox: drag any parts onto the breadboard, wire them however you like, and run your own sketches — the way real prototyping works.

Perfect for curious beginners, students, makers, and anyone who's always wanted to learn electronics but didn't know where to start.
