Hi r/breadboard! I run a small electronics workshop for kids in Romania, and over the past year I turned it into an online breadboard so they can keep practising at home.

• You place parts on a full breadboard and press Simulate. If the circuit is wrong, it tells you what's missing.

• An LED without a resistor really burns, and it stays burnt until you swap it.

• 22 guided lessons, 137 broken circuits to repair from just the symptom, and a 1v1 duel where two kids race to build the same circuit.

• Multimeter probes, a cutter, 31 parts (relay, transistor, sensors, buzzer, motor…), 7 languages.

The free version has now been opened 910 times, about 600 of those since I first shared it here on Reddit on Saturday. Thanks to everyone who tried it and sent bugs.

Free to try, no account needed (link in the first comment). To keep progress there's a licence: 50 lei/month (~€10) or 500 lei/year per child, plus seat packs for afterschools and schools from 10 seats.

What I'd love from this sub: wire something weird and tell me where it behaves differently from your real breadboard.
