Breadboard Circuit Simulator

Breadboard simulator for developers, students of electrical engineering and their teachers. Make your electronic constructions on the project board. Insert IC circuits, resistors, LED, switches. Connect them using cables, and watch the simulation. As you build your construction and alter the switches the voltage of various pins will change and LED:s light up. The voltage is displayed in colors from blue (0V) via purple to red (5V). There is also a built in probe that can measure and display the voltage more accurately. Currently 3 integrated circuits are available: 7400 (NAND), 7404 (NOT) and 74191 (Binary counter). Internally TTL (transistor transistor logic) inputs and outputs are simulated. To make the simulation more realistic, a LED will break if its current is too high!
