Learn electronics

Learn electronics on real circuits in your own project. Ask Flux a question, and Flux builds the circuit and explains each part. Flux is an AI hardware engineer. It teaches you as it designs, from your first LED circuit to a complete device.

Learn electronics by working with Flux on a circuit in your project. Flux explains each part as it builds an LED loop from a 3.3 V supply, through a resistor and LED, and back to ground.

Learn with an LED circuit

Ask Flux to guide you through a hands-on circuit. Flux can add the parts and connect them in your project while it explains how the circuit works.

I am new to electronics. Teach me how a circuit works with a hands-on example.
Build an LED circuit in my project and explain how the resistor, LED, and return path connect.
Show me the 3.3 V supply, resistor, LED, and ground path. What happens if I disconnect the return wire?

Flux adds a 3.3 V supply connection, a resistor, and an LED. It connects the supply positive through the resistor and LED, then returns to supply negative. Flux asks you to trace the path and predict what happens if you disconnect the return wire.
