My project is an electronic Art App controlled by Arduino Uno.

The app connects to Arduino port. goes full screen, and starts drawing abstract geometrical figures based on parameters it reads from the Arduino. The user can can control what the app is drawing using potentiometers, switches, and a push button. Everything can be controlled by Arduino, there is no need for keyboard and mouse (after connecting to Arduino port). App can be used for meditation, or just to relax. Drawings can be saved in real time using push button.

 

Push button 1 – clears app screen

Push button 2 - save the screenshot of the drawing

Switch 1 – Start/Stops drawing

Switch 2 – controls line type. Line type can be an Arc (Bezier curve) or a straight line

Potentiometer 1 – controls line width

Potentiometer 2 – controls an angle for a drawing

Potentiomenter 3 - controls drawing speed

 

The app itself is written in C#.NET. To communicate between .NET and Arduino I used open source Sharer library, it is awesome and it can be found here:

Fun fact: When testing the board I ran into a problem that all analogRead() functions returned incorrect values. I could not figure out why, it was driving me crazy. I was sure that I fried both of my Arduinos somehow. But finally I figured out that connections on my $1 breadboard were not wired properly. I changed the breadboard and everything started working right away.
