Digital Circuit Calculator

The application to recognize,calculate and store the hand-drawn digital circuits

This application allows users to draw logical gates and connect them together to form a digital circuit. The source is '0' and '1' which you can draw by clicking on the screen. A sink is set on the right middle screen to display the output of the whole circuit.

We use Paint/Canvas API to draw the images.

The recognition is done based on android Tensorflow Library and the Protocol Buffer file that we trained on Tensorflow.

The result image is the object extending from ImageButton widget.

The local database is embedded in the application using SQLite which automatically stores the hand drawn gate images and its corresponding prediction label to enable users to gather the statistical information of the recognition result.
