Tell us about your project:

My project is a Display with LEDs.

Besides scrolling text my project displays rotating borders and images.

All three functions can be accessed using 2 switches, so it is a four-state display.

The images displayed are easily created by using the links given below:

My question is: How do I automatically send the *.ino file to Arduino? When I download it to the computer I want Arduino to start running it. Do I need an Ethernet Shield?

Are there any links or files you'd like to provide that support your project?  Code snips, 3d print files, etc.
