This app is a digital circuit simulator. With this tool, users can build an 8-bit computer from simple logic gates by creating and connecting individual circuits that perform specific functions such as arithmetic and logic operations.

Thought behind the app

To understand the nature of computing and demonstrate what happens physically behind every touch on the screen.

I find ( Building an 8-bit breadboard computer! ) these series videos are an eye-opener. It makes me understand the physics of the information process. I wonder may I build an app to simulator the process. And it may easier to demonstrate the computer principles when you can hold it in your hand and touch it.

Logic Gates explain

To connect the basic logic to the measurable physical process, above are three sample illustrations about how semiconductors been used to do the basic logic operation. ( I also found a vivid video to explain that. )
