ASCII Art for Arduino Circuit Diagrams
A few examples from my code.
Here are a few handy ASCII diagrams for recording circuit setups inside of your Arduino sketches. I’ve found that making a habit of this is as important as commenting the code. These may look a little funky in your browser but they will line up nicely in plain text Arduino sketches.
Update: for some more current Arduino version ASCII pinouts (Mega, Uno, etc.), check out http://busyducks.com/ascii-art-arduinos.
