Hi
Hw can i Call diffrent Consts based on a nother Variable
For example

#define pin3 3
#define pin2 2
#define pin1 1 
foo = 3
digitalWrite(pin"foo", HIGH);

the "foo" should then be replaced with a 3. I know a switch but its too long for my application. i have ~30 pins.so it would be too long
Thanks

Use an array

You mean a two-dimensional array? We have those!
