The Process

Learn, Build, Simulate, Level Up

Four simple steps that turn any kid into a circuit builder in hours, not months.

Watch the Concept

Short animated videos explain voltage, current, and components - no boring textbooks.

Build in the Lab

Drag components onto the canvas, connect wires, and set up the circuit as shown.

Run Simulation

Hit Run and watch the physics come alive - see voltage, current, and LED glow in real time.

Earn & Level Up

Complete missions to earn XP, badges, and climb the weekly leaderboard with friends.

Platform Features

Everything a Young Engineer Needs

Real Physics Simulation

Every circuit is solved with actual nodal analysis - Ohm's Law, Kirchhoff's rules, diode models. Kids see real numbers, not fake animations.

  • Voltage and current at every node
  • LED forward-bias with glow effect
  • Short circuit and open circuit detection
  • "Why?" tooltips that explain every number

What They Say

Loved by Students, Parents & Teachers

"My daughter finished the LED Flasher mission in 20 minutes and immediately asked when she could do the next one. She's never been this excited about science."

"I use CircuitKids in my Year 8 science class. The teacher dashboard makes it incredibly easy to see who's on track and who needs help - without interrupting the lesson."

"I'm 12 and I built a real doorbell buzzer by myself after 3 weeks. The 'Why?' button is my favourite - it explains everything without making you feel stupid."
