Geniusses modify other's projects by putting their name in it
So load the blink project found in your Arduino folder and upload it.
Then modify it so it will blink in some different way (figure out yourself how you could vary on the blink theme, there are a few ways to do this).
After that let's get an extra LED plus resistor and have double fun.
And some more LEDs.
Do baby steps at start, even those baby steps are fun as long as you figure them out.
There's a bunch of examples you can try from the Arduino/Examples folder.
Just loading them doesn't prove your genius.
Making them do your variant does.
