the user interface was quite simple it has just has a canvas for drawing and different pen color choices
the user interface is below
 |
programming this app was relatively simple but took some thought the programmed blocks are below
|
 |
| all these block are programmed to do is when the user press these 3 buttons it will change the pen color |
 |
| the first block is to sense were you want to draw and it puts a line in were you have drawn on the screen the second block clears the screen when you shake it. |
