A macOS breadboard/project-board simulator — perfect for students and teachers of digital electronics.
Insert ICs, resistors, switches, and LEDs onto a virtual breadboard and connect them with cables. The simulator calculates voltages and lights up the LEDs accordingly.
Voltage is displayed in color — from blue (0 V) through purple to red (5 V). A built-in probe lets you measure and display voltages more precisely.
Currently supported ICs: 7400 (NAND), 7404 (NOT), and 74191 (Binary counter).
This app does not collect any data. It does not connect to the Internet — no network access is required.
