I am a beginner with Arduino, and to realize my project I decided to use the Seeeduino Film.
I'm starting to code before I receive it, and I have a simple (I guess) question :
Which Pin name/number should I use in my code for the Digital ports?
Because on the "datasheet" (seeeeduino garden), Digital ports are called D4, D5*, D6*, D7, D9*, D10*.
Then, if I want to use the 7th port as an output, should I write : pinMode(D7,OUTPUT) ? or pinMode(7,OUTPUT)?
And what about the stars in D5*, D6*, D9*, D10*?
Thanks for your help!
