Bit Grid for iPad
From Bit Grid
Based on the earlier Spreadsheet Circuit Board project, Bit Grid is a way to simulate logic circuits in an interactive way. Connect Boolean gates together to create a variety of simple circuits.
Create integer nodes to input integers into your project. Create circuits for addition, subtraction, two’s complement conversions and many more. Included are suggested projects which will get you started.
In this version, you will find a mode button to help you more easily create projects. Move all the nodes into place, then switch modes to connect them together.
You can also share projects by using the document sharing features available in iTunes.
