A student-run nonprofit
Hands-on electronics for elementary and middle school makers.
Book a workshopPick the one that sounds like you. Each path goes straight to the right page.
Coin cells, AA packs and USB: 3 to 5 volts. Never wall power.
Real components kids can hold and test, sized for small hands and short sessions.
Our forms are for adults. We never ask for student names or details.
Every activity on this site is free, with materials you can find at home or school.
Close the circuit and change the pulse rate to see what each part does.
The parts, laid out: power, a chip, wires, a resistor, an LED and a motor.
Each part has one job. The breadboard connects them.
The parts move into place and the wires connect.
The circuit closes: current flows, the LED lights and the motor turns.
Change the pulse rate and watch the motor and the signal respond.
So far:

Flip the paper switches. Try series, then parallel. Watch where the current goes.

Parallel · 3 V · D1 on · D2 off —
S1 closes the first branch. D2’s branch is still open.
Why? In parallel, each LED gets the full 3 V across its own branch, more than the ~2 V a red LED needs.
Challenge: can you light both LEDs in series?
Three free lessons, starting with a pencil and paper.
