CRUMB Circuit Simulator

Interactive and immersive learning
CRUMB offers an easy to use and interactive introduction to electronic circuitry. Fully realised in 3D, you can construct prototype circuits as you would at the workbench without the risk of terminal component failure or the hassle of ordering individual components. A broad selection of parts and features offers an insight into many different areas of modern electronics

Large catalogue of components
CRUMB has a varied selection of components, even at this early stage in its development. There are no limits to what circuits you can create. CRUMB includes several built-in examples which showcase some of the abilities of CRUMB. This list below highlights some of the included components

Passives such as Resistors, Capacitors and Inductors

Tactile, slide and DIP switches

Semiconductors such as Diodes, BJT Transistors, MOSFETs and Silicon Controlled Rectifiers

LEDS, Transducers, Seven Segment displays

LCD and TFT displays

DC Power and Signal Generators

Large selection of Integrated Circuits ranging from Basic to Complex Logic, Timers, Counters, Memory, EEPROM and Op Amps

Fully programmable Microcontroller
Advanced features
The latest update has expanded some of the special features included with CRUMB

Code Editor
The built-in Code Editor has been expanded to allow the viewing and editing of the Source Files that I have written for the programmable Microcontroller included in CRUMB

Hex Editor
This is an EEPROM available to use which can be programmed via circuitry (see built-in example) or values can be entered manually with the built-in hex editor

Scope Analysis
Up to 4 components can be added to the built-in scope, allowing you to view the intricacies of your circuit

Visualisation
CRUMB offers a set of different visualisations tools. You can view current and voltages in the wires, logic output at the pins of various components, highlight the pin labels and anodes of polarized components and switch off the scene lighting for dark mode
