Crumb Circuit Simulator

Crumb Circuit Simulator is a 3D circuit-building game that introduces electronic circuitry. You assemble prototype circuits as you would at a workbench, without the risk of component failure or the need to order individual parts. Its components and tools cover a range of areas in modern electronics, and built-in examples demonstrate some of the circuits you can make.

Components

The component catalogue includes:

• Passive components such as resistors, capacitors and inductors
• Tactile, slide and DIP switches
• Diodes, BJT transistors, MOSFETs and silicon-controlled rectifiers
• LEDs, transducers and seven-segment displays
• LCD and TFT displays
• DC power supplies and signal generators
• Integrated circuits for logic, timers, counters, memory, EEPROM and operational amplifiers, from basic to complex
• A programmable microcontroller

Circuit tools

The built-in Code Editor lets you view and edit the source files for the included programmable microcontroller. You can program an EEPROM through circuitry, as shown in a built-in example, or enter values manually with the Hex Editor.

The scope displays readings from up to four components. Visualisation tools show current and voltage in wires and logic output at component pins, highlight pin labels and the anodes of polarized components, and let you turn off scene lighting for dark mode.
