About CRUMB
CRUMB offers an easy to use and interactive introduction to electronic circuits
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
CRUMB comes with a great selection of components to allow you to jump straight in to creating prototype circuits
With the catalogue available, it is possible to study the workings of transistors & audio filtering, all the way to programming an EEPROM to run a basic program
For the beginner, it is possible to learn and understand the basics of interactivity, and for the enthusiast it is possible to analyse and perfect prototypes before constructing real world models
Using the built in oscilloscope and analysis views, it is possible to see clearly the interaction between components from within the wires themselves
Through community feedback and suggestion, there will be many more components and features added. For a full feature list and development schedule please visit the website http://www.crumbsim.com
