Electronics you can see and change

Build a circuit. Watch it work.

Start with voltage and current, then add logic, sensors, motors and code. Change a component, run a simulation, and see the measurements update.

Learn by building up

From electrons to intelligent devices.

Each module adds a new layer, from the physics of a component to a complete sensing, computing and control system.

01 / SEE IT

Make invisible ideas visible

Trace current, see a capacitor charge, and check what happens when a component value changes.

02 / CODE IT

Connect electronics and Python

Use Arduino C++ to read the physical world, then Python to analyse the data and make decisions.

03 / BUILD IT

Put the whole system together

Design practical projects with sensors, actuators, safe control and AI at the edge.
