Light your first bulb - then build a working computer adder from real parts. Electro Master is a friendly electronics lab: 27 short lessons with Voltik the robot take you from a simple circuit to transistors, logic gates and memory. Or jump straight into the infinite sandbox and invent anything you like. Parts behave like the real thing: miswire a battery and it shorts, overload a bulb and it burns out. Open ready-made circuits like an 8-bit adder, flip the switches and watch them think.
Pick a part from the left and drag it between neighboring dots to build circuits. Use the hand tool to flip switches and inputs, and use the erase tool or Delete to remove parts. You can also zoom, pan, undo, redo, and save your creations.
Electro Master is an electronics simulation and puzzle game that teaches circuit building, logic gates, transistors, and computer fundamentals through interactive experiments.
The goal is to learn how electronic circuits work, complete the 27 lessons, and eventually build working circuits such as an 8-bit computer adder.
You solve circuit-building and logic puzzles by connecting components correctly. The lessons gradually introduce bulbs, transistors, logic gates, memory, and more complex computer circuits.
Yes. The lessons encourage logical thinking and problem-solving, while the infinite sandbox gives you the freedom to experiment and invent your own circuits.
