Welcome to SparkLab
Design circuits on screen. Build them for real.
Pick parts from the library, wire them up on your canvas, and watch the LED light up in the browser. When you’re ready to go physical, SparkLab hands you the exact shopping list and step-by-step instructions to build the same circuit on a real breadboard.

How it works
Three steps from idea to working circuit.
- 01
Pick parts from the library
Browse real components — LEDs, resistors, batteries, switches — organised by what they do.
- 02
Wire them up on the canvas
Drop parts onto the grid and drag wires between them. Press Run to watch current flow.
- 03
Get your parts list and build it
When the circuit works on screen, SparkLab prints what to buy and how to wire it for real.
Inside the Studio
One canvas. Everything you need within reach.
