Learn electronics by making circuits

Build
something
that lights up.

Start with an LED. Add a resistor. Find out why it works.

01 / The first spark

Start with one LED.
Then ask why it lights.

Start with something you can actually make. Follow what happens, change one thing, and see the circuit respond.

→No experience needed to begin.
02 / Choose your setup

One lesson.
Two workbenches.

Follow the path with real components, or learn the concepts on screen. Cirq's browser breadboard is in development.

With parts.

Make a circuit you can hold.

On screen.

Follow the learning path and try the activities as they open.

What you'll build
in Unit 1.

These are the planned hands-on builds. Lessons open on the path as each is ready.

01 / FIRST LIGHT

Light one LED.

Battery, resistor, LED. Make the first circuit work.

02 / TRAFFIC LIGHTS

Make a traffic light.

Try the LEDs in series and in parallel.

03 / HOLD THE GLOW

Hold the glow.

See what happens after power is disconnected.

Why we built Cirq.

We learned many everyday engineering ideas only after reaching engineering classes. Cirq is a place to try those ideas earlier by actually building.
