hi, i would like to use the analog input pins as digital pins, just wondering what to do is the structure section with regards to the Int characters, how to change the pin o analog to digital, cant see anything in the reference section thank you
Just use them - A0 to A5 are D14 to D19. Nothing special to do.
cant see anything in the reference section
Not looking closely enough. Like here
just wondering what to do is the structure section with regards to the Int characters,
I don't understand that phrase.
int greenled = 1; for a digital pin
what phrase do we do for an analog a0 pin? thank you
const int greenled = A0;
const int greenled = 14; 14 = 13 + 1
will also work for the Arduino UNO as CrossRoads suggested, being 14 = lastdigitalpininyourboard + 1, specially useful if you are working with your pins inside a loop.
