Recent updates allow simulation frequencies up to 96,000 Hz, enabling the creation of working 8-bit CPUs. Platform & Requirements
CRUMB Circuit Simulator is a real-time 3D electronics simulator designed for interactive learning and prototyping on a virtual breadboard. It allows users to build complex circuits using a wide range of components—from basic resistors and LEDs to programmable microcontrollers like the Arduino Nano—without the risk of hardware damage.
